Summary
Men with elevated post-void residuals (PVRs) face acute urinary retention (AUR) risk. Increased prostate volume or PSA levels predict this risk, guiding early intervention decisions.
Area of Science:
- Urology
- Andrology
Background:
- Elevated post-void residuals (PVRs) are common in men.
- Predicting acute urinary retention (AUR) risk is crucial for timely intervention.
Purpose of the Study:
- To identify predictors of AUR in men with elevated PVRs.
- To evaluate the role of prostate volume and PSA in AUR development.
Main Methods:
- Retrospective analysis of 44 male patients with consecutive PVRs > 100 ml.
- Regression analysis of age, PVR volume, PSA, and prostate volume for AUR development over 24 months.
Main Results:
- Prostate volume was a significant predictor of AUR (p=0.003).
- PSA also predicted AUR (p=0.007) when prostate volume was excluded.
- A 1-SD increase in prostate volume (12 ml) increased AUR risk by 19.6%.
Conclusions:
- Transrectal ultrasound prostate volume and PSA can predict AUR risk in men with elevated PVRs.
- These findings may guide early surgical versus medical management decisions.

Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1.

AssessmentSubjective Data: Obtain a detailed health history, including any recent or chronic urinary tract infections, periods of immobilization, previous episodes of renal calculi, and medical conditions such as gout, benign prostatic hyperplasia, or hyperparathyroidism. Review the medication history for drugs that may influence stone formation, including allopurinol, analgesics, loop diuretics, or thiazide diuretics. Document the use of long-term indwelling catheters and any past surgical...

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
