Symptoms and Signs – Differential Diagnosis of Hematuria
Hematuria is an essential indicator of renal and urinary tract diseases, characterized by the undesired occurrence of blood in urine. More precisely, it refers to the presence of three or more red blood cells (RBCs) per high-power microscopic field in urine. A confirmation of microscopic hematuria is obtained by an occult blood test, although macroscopic hematuria is readily apparent. However, it is important to differentiate macroscopic hematuria from pseudohematuria. See Confirming Hematuria. Hematuria by macroscopic examination
May manifest as either continuous or intermittent, is often accompanied by pain, and can be worsened by extended periods of standing or walking.
Verification of Hematuria
To diagnose the patient with blood-tinged urine, ensure to exclude pseudohematuria, which is the presence of red or pink urine resulting from urinary pigments. Prioritise meticulous examination of the urine sample. The presence of crimson sediment almost certainly indicates real hematuria.
Furthermore, verify the patient's medical records for the administration of medications linked to pseudohematuria, such as rifampin, chlorzoxazone, phenazopyridine, phenothiazines, doxorubicin, phensuximide, phenytoin, daunomycin, and laxatives containing phenolphthalein.
Inquire about the patient's consumption of beets, berries, or foods containing red colored pigments that could potentially cause the urine to appear red. Notably, pseudohematuria can also be caused by porphyrinuria and excessive urate excretion.
Lastly, analyze the urine by means of a chemical reagent strip. This assay can definitively detect even minute hematuria and can also approximate the quantity of blood in the urine.
Hematuria can be categorized dependent on the specific stage of urination that it mostly impacts. Initial hematuria refers to bleeding at the beginning of urination, which often suggests urethral disease. Terminal hematuria refers to bleeding at the end of urination, which typically indicates disease of the bladder neck, posterior urethra, or prostate. Total hematuria refers to bleeding throughout urination, which typically indicates an underlying disease above the bladder neck.
Hematuria can occur due to two mechanisms: either the rupture or perforation of blood vessels in the renal system or urinary tract, or the decreased filtration of ROBCs into the urine caused by impaired glomerular function. The hue of the hematuric urine offers insight into the origin of the hemorrhage. In general, dark or brownish blood signifies bleeding in the kidneys or upper urinary tract, while bright red blood denotes bleeding in the lower urinary tract.
While hematuria is commonly associated with renal and urinary tract diseases, it can also arise from specific gastrointestinal, prostate, vaginal, or coagulation illnesses, as well as from the effects of certain medications. Hematuria can also be caused by invasive interventions and diagnostic investigations that require manipulative instrumentation of the renal and urologic systems. Fever and associated nonpathologic hematuria may occur.
States of hypercatabolism. After intense physical activity, transient hematuria may occur.
History and Physical Examination
Following the identification of hematuria, obtain a relevant medical history. In cases of macroscopic hematuria, inquire about the patient's initial observation of blood in their urine. Does its harshness differ between voidings? Does it exhibit more severity during the onset, middle, or conclusion of urination? Has this happened previously? Has the patient exhibited thrombotic events? Request information regarding bleeding hemorrhoids or the initiation of menstruation, if relevant, to exclude the possibility of artifactitious hematuria. Ask if there is any sensation of pain or burning during episodes of hematuria.
Inquire about any incidence of recent abdominal or flank trauma. Has the patient engaged in intense physical activity? Document any previous occurrences of renal, urinary, prostatic, or coagulation abnormalities. Then get a medication history, specifically mentioning anticoagulants or aspirin.
The physical examination should commence with the application of pressure and percussion to the abdomen and flanks. Next, apply pressure to the costovertebral angle (CVA) to evoke tenderness. Conduct a thorough examination of the urinary meatus for any signs of blood or irregularities. Utilise a chemical reagent strip to analyse a urine sample for protein content. Either a vaginal or digital rectal examination may be required.
Medical Causes
Bladder cancer
Bladder cancer, a leading cause of gross hematuria in males, can also bring about pain in the bladder, rectum, pelvis, flank, back, or leg. Additional typical symptoms include nocturia, dysuria, increased frequency and urgency of urination, vomiting, intestinal distress, and sleeplessness.
Bladder trauma
A distinctive feature of traumatic bladder rupture or perforation is the presence of gross hematuria. Commonly, hematuria is accompanied with lower abdomen pain and, in rare cases, anuria despite a strong urge to urinate. In addition, the patient may experience edema in the scrotum, buttocks, or perineum, as well as the manifestation of shock symptoms like rapid heart rate and low blood pressure.
Calculi
Hematuria produces by bladder and renal calculi may be accompanied by symptoms of a urinary tract infection (UTI), including dysuria and increased frequency and urgency of urination. Typically, bladder calculi result in gross hematuria, pain that radiates to the lower back, penile, or vulvar region, and, in certain cases, bladder distension.
Renal calculi can cause either microscopic or extensive hematuria. The primary indication, however, is the abrupt and intense pain that radiates from the central venous artery to the flank, suprapubic area, and external genitalia upon the passage of a calculus. The Pain can be absolutely agonizing at its maximum intensity. Additional indications and manifestations may encompass emesis, agitation, pyrexia, rigor, excessive abdominal distension, and, potentially, diminished gastrointestinal noises.
Cortical necrosis (acute)
In acute cortical necrosis, the presence of gross hematuria is accompanied with severe flank pain, urinary retention, increased white blood cell count, and fever.
Cystitis
Hematuria is a characteristic feature in all forms of cystitis. The typical presentation of bacterial cystitis is macroscopic hematuria accompanied by urine urgency and frequency, dysuria, nocturia, and tenesmus. The patient presents with perineal and lumbar pain, suprapubic discomfort, exhaustion, and intermittent episodes of low-grade fever.
Most prevalent in women, persistent interstitial cystitis sometimes results in visibly bloody hematuria. Characteristics commonly associated with this condition are increased frequency of urination, dysuria, nocturia, and tenesmus. In tubercular cystitis, microscopic and macroscopic hematuria might manifest, along with symptoms such as urine urgency and frequency, dysuria, tenesmus, flank discomfort, weariness, and anorexia. A typical presentation of viral cystitis is hematuria, urine urgency and frequency, dysuria, nocturia, tenesmus, and fever.
Diverticulitis
Should diverticulitis affect the bladder, it often results in microscopic hematuria, increased frequency and urgency of urination, dysuria, and Nocturia. Characteristic observations include pain in the lower left quadrant, tenderness in the abdomen, constipation or diarrhea, and occasionally a palpable, firm, fixed, and tender mass in the abdomen. In addition, the patient may experience slight nausea, flatulence, and a low-grade temperature.
Glomerulonephritis
Initial symptoms of acute glomerulonephritis often include gross hematuria, which gradually progresses to microscopic hematuria and red cell casts, and can last for several months. In addition, it can cause oliguria or anuria, proteinuria, a slight temperature, weariness, inflammation of the flank and abdomen, widespread swelling, elevated blood pressure, nausea, vomiting, and indications of lung congestion, such as crackles and a productive cough.
Primary manifestations of chronic glomerulonephritis can include microscopic hematuria, proteinuria, widespread edema, and elevated blood pressure. In severe stages of renal illness, signs and symptoms of uremia may also manifest.
Chronic interstitial nephritis
The usual manifestation of nephritis is microscopic hematuria. The patient suffering from acute interstitial nephritis may, however, experience gross hematuria. Additional features include pyrexia, a maculopapular eruption, and reduced urine output or absence of urine. In chronic interstitial nephritis, the patient presents with urine that is dilute, nearly colorless, and may be accompanied by excessive urination and elevated blood pressure.
Nephropathy (obstructive). Although microscopic or macroscopic hematuria may be caused by obstructive nephropathy, urine is seldom visibly colored with blood. The patient presents with colicky flank and abdominal pain, tenderness in the cerebrovascular accident (CVA), and alternating episodes of anuria or oliguria as well as polyuria.
Polycystic kidney disease
The inherited condition known as polycystic kidney disease can result in recurring microscopic or large hematuria. Predominantly asymptomatic until the age of 40, this condition can lead to elevated blood pressure, excessive urination, dull flank discomfort, and indications of a urinary tract infection, such as dysuria and urine frequency and urgency. In due course, the patient experiences an enlarged and sensitive belly, as well as lumbar discomfort that is worsened by physical activity and alleviated by reclining. Additionally, he may experience proteinuria and colicky abdominal pain caused by the presence of clots or stones in the ureteral canal.
Prostatitis
Prostatitis, whether acute or chronic, can result in visible blood in the urine, often detected at the end of urination. The condition may also cause increased frequency and urgency of urination, as well as dysuria accompanied by noticeable distension of the bladder. The clinical manifestations of acute prostatitis include fatigue, malaise, myalgia, polyarthralgia, fever accompanied by chills, nausea, vomiting, perineal and low back discomfort, and a reduced libido. Upon rectal probing, a painful, bloated, swampy, firm
prostate.
Typically, chronic prostatitis occurs after an acute inflammation. It can result in chronic urethral discharge, dull perineal soreness, ejaculatory symptoms, and reduced sexual desire.
Pyelonephritis (acute). One common manifestation of acute pyelonephritis is the development of microscopic or macroscopic hematuria, which then advances to severely bloody hematuria. Following the resolution of the illness, microscopic hematuria may continue for a few months. Associated indications and manifestations include a chronic elevated body temperature, pain in one or both flanks, sensitivity to cerebrovascular accidents (CVAs), tremors, debility, exhaustion, urinary retention, increased frequency and urgency of urination, night sweats, and heightened pulse rate. Furthermore, the patient may present with symptoms of nausea, anorexia, vomiting, and indications of paralytic ileus, such as reduced or nonexistent bowel sounds and abdominal distension.
Renal cancer
Typical symptoms include visibly crimson urine, chronic side pain, and a palpable lump or tumor in the either the side or abdomen. Passage of clots may be accompanied by colicky pain. Additional observations include pyrexia, constriction of the cerebral arteries, and elevated blood pressure. With severe disease, the patient may experience weight loss as well as nausea and vomiting.
Renal infarction
As a general rule, renal infarction results in gross hematuria. The patient may present with persistent, intense flank and upper abdomen discomfort accompanied by tenderness in the central venous artery, loss of appetite, and feelings of nausea and vomiting. Further observations include the presence of oliguria or anuria, proteinuria, hypoactive bowel sounds, and, within one to two days following the infarction, a fever and elevated blood pressure.
Renal papillary necrosis (acute)
An acute renal papillary necrosis often results in visibly bloody hematuria, followed by severe flank pain, discomfort in the carotid artery, abdominal stiffness and colicky pain, oliguria or anuria, pyuria, fever, chills, vomiting, and hypoactive bowel sounds. Prevalence of arthritis and hypertension is high.
Renal trauma
Approximately 80% of those who have experienced renal trauma have either microscopic or gross hematuria. Potential accompanying manifestations may encompass flank pain, a detectable mass on the flank, reduced urine output, hematoma or ecchymoses on the upper abdomen or flank, nausea and vomiting, and reduced bowel noises. Serious injury can trigger symptoms of shock, including rapid heart rate and low blood pressure.
Renal tuberculosis
First indication of renal TB is often gross hematuria. Concomitant symptoms include increased frequency of urination, difficulty urinating, excessive urination, muscle tension, painful abdomen, back discomfort, and presence of protein in the urine.
Renal vein thrombosis
Hematuria with gross bloodstained appearance often arises in cases of renal vein thrombosis. An abrupt venous blockage is characterized by the patient experiencing Persistent flank and lumbar pain, together with tenderness in the epigastric and CVA regions. Additional characteristics include pyrexia, pallor, proteinuria, peripheral edema, and, in cases of bilateral blockage, oliguria or anuria along with other uremic complications. The kidneys can be readily palpated. Progressing blockage of the veins leads to symptoms of nephrotic syndrome, proteinuria, and, in rare cases, peripheral edema.
Schistosomiasis
Schistosomiasis often results in sporadic hematuria occurring with urine. Complicating symptoms may include dysuria, colicky renal and bladder pain, and palpable lumps in the lower abdomen.
Sickle cell anemia
Sickle cell anemia is an inherited condition characterized by the presence of extensive hematuria occurring due to the congestion of the renal papillae. Common concomitant manifestations may encompass pallor, dehydration, persistent fatigue, polyarthralgia, leg ulcers, dyspnea, chest pain, hindered growth and development, hepatomegaly, and perhaps, jaundice. Auscultation detects rapid heart rate and murmurs of both systolic and diastolic contractions.
Systemic lupus erythematosus (SLE)
Gross hematuria and proteinuria may occur when SLE attacks the kidneys. The primary characteristics commonly linked with this condition are nondeforming joint pain and stiffness, a butterfly rash, sensitivity to light, Raynaud's phenomena, seizures or psychoses, a recurring fever, lymphadenopathy, oral or nasopharyngeal ulcers, anorexia, and weight loss.
Urethral trauma. Primary hematuria may manifest as blood in the urine meatus, accompanied by localised discomfort and ecchymoses in the penis or vulva.
Vasculitis often presents with microscopic hematuria. Common manifestations include fatigue, muscle soreness, pain in many joints, elevated body temperature, elevated blood pressure, paleness, and, sometimes, abnormal urine output. Additional symptoms, such as urticaria and purpura, probably indicate the cause of vasculitis.
Medical diagnostic testing. A renal biopsy is the diagnostic procedure most often linked to hematuria. A biopsy or manipulative instrumentation of the urinary system, such as in cystoscopy, may also cause this indication. Substance abuse. Pharmacological substances that frequently induce hematuria include anticoagulants, aspirin (with potential toxicity), analgesics, cyclophosphamide, metyrosine, phenylbutazone, oxyphenbutazone, penicillin, rifampin, and thiabendazole.
When used in conjunction with an anticoagulant, herbal treatments, such as garlic and
Administration of Ginkgo biloba may result in unfavourable responses, such as profuse bleeding and hematuria.
Therapeutic interventions. Therapeutic procedures that include the use of manipulative instruments to manipulate the urinary system, such as transurethral prostatectomy, have the potential to induce either microscopic or macroscopic hematuria. Following a kidney transplant, a patient may develop hematuria, with or without clots, necessitating the use of an indwelling urinary catheter for irrigation.
Points of Special Consideration
As hematuria might generate fear and distress in the patient, ensure to offer emotional support. Assess his vital signs at minimum every four hours and monitor fluid intake and output, including the volume and pattern of hematuria. Verify the patency of the indwelling urinary catheter in the patient and, if needed, irrigate it to eliminate any clots and tissue that could hinder urine outflow. Administer prescription analgesics and compel confinement to bed as necessary. Schedule the patient for diagnostic examinations, including blood and urine testing, cystoscopy, and renal X-rays or biopsies.
Therapeutic Counseling for Patients
Provide the patient with instructions on the three-glass approach for collecting sequence urine samples. Highlight the necessity of augmenting his consumption of fluids.
Guidelines for Pediatric Populations
A significant number of the factors outlined in this section also result in hematuria in children. Cyclophosphamide is somewhat more prone to induce hematuria in children than to adults.
Primary etiologies of hematuria in children include congenital abnormalities, such as obstructive uropathy and renal dysplasia; birth trauma; hematologic diseases, including vitamin K deficiency, hemophilia, and hemolytic-uremic syndrome; specific malignancies, such as Wilms tumor, bladder cancer, and rhabdomyosarcoma; allergies; and the presence of foreign agents in the urinary tract. Artifactual hematuria can occur as a consequence of surgical circumcision.
Geriatric Guidelines
Thorough assessment of hematuria in older people should involve a urine culture, excretory urography or sonography, and seeking advice from a urologist.
