Topographic anatomy of the male perineal structures with special reference to perineal approaches for radical prostatectomy

Aim: Although perineal approaches for radical prostatectomy have recently gained renewed attention as excellent methods for minimally invasive surgery, the most commonly used techniques, Belts and Youngs approaches, have inadequacies regarding the topographical relationship between the rectourethral and levator ani muscles.

Impact of radical perineal prostatectomy on urinary continence and quality of life: A longitudinal study of Japanese patients

Aim: We used self‐completed questionnaires to obtain a longitudinal assessment of urinary continence and urinary, bowel, and sexual domain‐related quality of life (QOL) in Japanese patients undergoing radical perineal prostatectomy (RPP).

Overactive bladder in children should be strictly differentiated from monosymptomatic nocturnal enuresis.

Introduction: To elucidate the prevalence of concomitant overactive bladder in children with a chief compliant of primary enuresis, and to evaluate the pathogenetic difference between monosymptomatic and non-monosymptomatic enuresis. Materials and Methods: All patients had evidence of primary enuresis. Neurogenic bladder was excluded. Urinary symptoms were evaluated by taking a history from the affected children and parents, and using a questionnaire and bladder diary. Voiding cystourethrography was performed for non-responders to exclude urinary abnormalities. Results: Eighty-eight patients (9.8 ± 3.1 years old) were enrolled. Initial assessment demonstrated that 24% had undervalued overactive bladders and 9% had constipation. Voiding cystourethrography was performed in 25%, demonstrating mechanical urethral obstructions in 8% and vesicoureteral reflux in 4.5%. Constipation, a history of urinary tract infections, mechanical obstructions and vesicoureteral reflux were strongly associated with non-monosymptomatic enuresis. Conclusions: Patients with non-monosymptomatic enuresis had a different clinical background, therapeutic response and pathogenetic abnormalities. In children an overactive bladder should be strictly differentiated from monosymptomatic enuresis.
