Complex, proximal, anteriorly located urethral diverticula present the reconstructive urologist with a uniquely challenging task for repair through a conventional transvaginal approach. Herein, we present the first report of urethral diverticulectomy to excise a large, anterior, horseshoe-shaped urethral diverticulum that resulted in bladder outlet obstruction, using a transabdominal robot-assi...

We report an unusual complication caused by urethral catheterization. During a routine urethral catheter change in a 38-yr-old woman, a 14-Fr Foley catheter was accidentally placed into the right ureter through the ureteral orifice. The position of the catheter was confirmed by retrograde urogram through urethral catheter. Percutaneous nephrostomy was performed with subsequent proper replacemen...

Feline urethral obstruction is a life-threatening condition that requires immediate treatment to relieve the obstruction. If medical dissolution not indicated, surgical intervention (e.g., open cystotomy, laparoscopic assisted percutaneous cystolithotomy) necessary remove uroliths, and minimally invasive surgery may offer some advantages. This case report describes successful management of usin...

PURPOSE Phosphodiesterase type 5 inhibitors were recently introduced as a new treatment option for men with lower urinary tract symptoms. Safety and clinical effectiveness are well documented but the mode of action is still unclear. We determined and compared the expression of phosphodiesterase type 5 in the spinal cord of normal (sham operated) rats and rats with partial urethral obstruction i...

OBJECTIVE To discuss clinical signs, diagnostic tools and therapeutics of anterior urethral valves, an obstructive anomaly of the urinary system in males. DESCRIPTION Signs of urinary tract obstruction were identified on pre-natal ultrasound in two male fetuses and the diagnosis of anterior urethral valves was made through post-natal evaluation. As an initial treatment, vesicostomy was perfor...
