Symptoms and Signs – Differential Diagnosis of Bladder distension
The abnormal enlargement of the bladder known as bladder distention is caused by the inability to effectively eliminate urine, leading to its accumulation. A mechanical or anatomical blockage, neuromuscular dysfunction, or the use of specific medications can all result in distention. Although prevalent in individuals of all age groups and genders, it is most prevalent in elderly males with prostate diseases that result in urinary retention.
Distention typically progresses gradually, however it may sometimes manifest suddenly. Typically, gradual distension does not cause any symptoms until the bladder is stretched and gives rise to discomfort. Acute distention presents with suprapubic enlargement, pressure, and discomfort. Without timely correction of significant distension with catheterization or massage, the bladder will ascend within the abdomen, its walls will weaken, and renal function may be compromised.
The consumption of caffeine, alcohol, excessive fluid intake, and diuretics exacerbates bladder distention.
Benign prostatic hyperplasia (BPH)
With benign prostatic hyperplasia (BPH), bladder distension occurs gradually as the prostate gland grows larger. At times, its onset exhibits acute characteristics. Initially, the patient presents with urinary difficulty, straining, and frequency; decreased force and inability to halt the urine stream; nocturia; and dribbling after voiding. As the condition advances, it causes hypertrophy of the prostate, feelings of fullness above the pubic bone and partial emptying of the bladder, pain in the perineum, constipation, and the presence of blood in the urine.
Bladder calculi
While bladder calculi can cause bladder distention, they often only cause pain as the primary symptom. The pain is often localized to the apex of the penis, the vulva region, the dorsal aspect of the back, or the plantar aspect of the heel. Pain exacerbates during ambulation or physical activity and alleviates when the patient assumes a supine position. Additionally, it may be accompanied by increased frequency and urgency of urination, terminal hematuria, and dysuria. The pain is often most intense when micturition stops.
Bladder cancer. The obstruction of the urethral opening by neoplasms might result in bladder distension. Associated signs and symptoms include hematuria (most prevalent indication), increased frequency and urgency of urination, nocturia, dysuria, pyuria, bladder, rectal, pelvic, flank, back, or leg discomfort, vomiting, diarrhea, and insomnia. On bimanual examination, a palpable lump may be detected.
Multiple sclerosis
Disruption of upper motor neuron regulation of the bladder in multiple sclerosis leads to a neuromuscular condition characterized by urine retention and bladder distention. Optic neuritis, paresthesia, impaired position and vibratory senses, diplopia, nystagmus, dizziness, abnormal reflexes, dysarthria, muscle weakness, emotional lability, Lhermitte’s sign (transient, electric-like shocks that propagate down the body when the head is flexed), Babinski’s sign, and ataxia are among the associated signs and symptoms.
Prostate carcinoma
An estimated 25% of men with prostate cancer ultimately develop bladder distension. Common manifestations include urine retention, increased frequency and urgency of urination, nocturnal nocturia, loss of body weight, exhaustion, pain in the perineum, constipation, and hardening of the prostate or an inflexible, irregular prostate during digital rectal examination. For some patients, the sole indications are urine retention and bladder distension.
Prostatitis
. With acute prostatitis, bladder distention occurs rapidly along with perineal discomfort and suprapubic fullness. Other signs and symptoms include perineal pain; a tense, boggy, tender, and warm enlarged prostate; decreased libido; impotence; decreased force of the urine stream; dysuria; hematuria; and urinary frequency and urgency. Additional signs and symptoms include fatigue, malaise, myalgia, fever, chills, nausea, and vomiting.
With chronic prostatitis, bladder distention is rare. However, it may be accompanied by sensations of perineal discomfort and suprapubic fullness, prostatic tenderness, decreased libido, urinary frequency and urgency, dysuria, pyuria, hematuria, persistent urethral discharge, ejaculatory pain, and a dull pain radiating to the lower back, buttocks, penis, or perineum.
Spinal neoplasms.
Disrupting the regulation of the bladder by higher neurons, spinal neoplasms lead to neurogenic bladder and subsequent distension. The characteristic indications and symptoms include a feeling of fullness in the pelvis, persistent dribbling overflow, back pain that usually resembles sciatica pain, constipation, sensitive spinal processes, sensory impairments, and muscle weakness, flaccidity, and atrophy. Common manifestations of urinary tract infection include dysuria, increased frequency and urgency of urination, nocturia, tenesmus, hematuria, and weakness.
Urethral calculi.
The presence of urethral calculi results in bladder distension due to urethral blockage. The patient presents with postural dysuria. Pain resulting from the blockage radiates to the penis or vulva and is referred to the perineum or rectum. It may also result in the formation of a palpable stone and urethral discharge.
Urethral stricture.
Urinary retention and bladder distension with chronic urethral discharge are the most prevalent symptoms of urethral stricture.
Other typical symptoms include frequency, dysuria, urgency, reduced force and width of the urine stream, and pyuria. As well, urinoma and urosepsis may occur.
Catheterization
The use of an indwelling urinary catheter might lead to the retention of urine and distension of the bladder space. Insufficient drainage caused by kinked tubing or an obstructed lumen while the catheter is in position might result in renal retention. Moreover, a misplaced urinary catheter or irritation during catheter removal can lead to swelling or spasms of the detrusor muscle and the external urethral sphincter, therefore obstructing the outlet of urine.
Substance abuse
Retention of urine and distension of the bladder can be caused by parasympatholytics, anticholinergics, ganglionic blockers, sedatives, anesthetics, and opiates.
Key Factors to Consider
Assess the patient's vital signs and measure the degree of bladder distension. Prompt the patient to alter their postures in order to relieve painful sensations. The patient may need an analgesic.
Book the patient for diagnostic procedures, including endoscopy and radiologic scans, to ascertain the underlying reason of bladder distension. If treatments prove ineffective in alleviating bladder distention and blockage hinders catheterization, it may be necessary to make him ready for surgery.
Therapeutic Counseling for Patients
Provide instruction to the patient on the utilization of Valsalva's maneuver or Credé's technique for bladder emptying. Provide instructions on how to induce voiding.
Guidelines for Pediatric Populations
Monitor for urine retention and bladder distension in newborns who do not empty their bladders adequately. Infants produce around 60 mL of urine within the first 48 hours of life, and their daily pee output increases to over 300 mL throughout the following week. Obstruction of the posterior urethral valves, meatal stenosis, phimosis, spinal cord abnormalities, bladder diverticula, and other congenital abnormalities in males can lead to urine retention and subsequent bladder distension.
