Acute urinary retention is one of the most frequent urologic emergencies. It occurs mostly in elderly males that suffer from prostate enlargement. Very rare in women, it is essentially caused by vaginal prolapse and neurologic disease. Patients with acute urinary retention suffer from lower abdominal pain and cannot void. Medical history is the cornerstone of diagnosis. Rarely palpable on abdominal examination, an overfilled bladder may be revealed by dullness on supra-pubic percussion. Acute urinary retention may lead to a decrease in kidney function, and on the long term to detrusor hypocontractility. The initial management is bladder drainage by urethral or suprapubic catheterization. Post obstructive diuresis and hematuria are possible complications. Subsequent evaluation is performed by the urologist on an ambulatory basis.

Water vapor thermal therapy for treatment of lower urinary tract symptoms due to large benign prostatic hyperplasia (≥ 80 g).
World J Urol

Department of Urology, AP-HM, North Hospital, Marseille, France.
Introduction: Water vapor thermal therapy (WVTT; REZUM™; Boston, USA) offers symptom relief with reduced risks of complications in patients with lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). WVTT therapy has been validated in the pivotal study in men with smaller prostates (< 80 cc). Yet, its feasibility for larger prostates (≥ 80 cc) remains underexplored.

Prostatic urethral lift (UroLift) is a budding minimally invasive technique that utilises mechanical manipulation of the prostate tissue so that the urethra is free from compression, thereby creating a channel for the outflow of urine. The aim of the audit was to assess the short- to medium-term outcomes in our centre in terms of improvement in symptoms, quality of life (QoL) and complication rates.

We report here a rare case of a concurrent occurrence of abscesses caused by in the prostate, seminal vesicles, and epididymis. A 71-year-old male presented to our hospital with urinary retention, and an indwelling urethral catheter was inserted. He remained afebrile until a revisit one month later when he developed a fever and left scrotal swelling.

Vaginal atresia is often accompanied by multiple organ malformations. The condition poses significant challenges in diagnosis and management, requiring a multidisciplinary approach.

Low Urin Tract Symptoms
January 2025
Allergan, an AbbVie Company, Marlow, UK.
Objectives: To evaluate possible predictors of elevated postvoid residual volume (PVR) following onabotulinumtoxinA administration in patients with idiopathic overactive bladder (OAB), a condition that may include urinary urgency, frequency, and nocturia, without any identifiable cause or underlying neurological or metabolic condition.
Methods: Adults who had been treated with 100-200 U onabotulinumtoxinA for OAB and had previous failure of other OAB treatments were identified by retrospective review of medical chart data from three urology clinics in the United States treating patients with a variety of urological conditions. A total of 211 patients were allocated to cohorts based on posttreatment PVR < 200 mL (n = 173) and ≥ 200 mL (n = 38).
