Lower urinary tract symptoms and OAB are prevalent among Korean men and women and the prevalence increases with age. Storage LUTS is more prevalent than voiding or post-micturition LUTS and nocturia is the most common symptom.

PurposeUrologic injuries occur frequently during surgery in the pelvic cavity. Inadequate diagnosis and treatment may lead to severe complications and side effects. This investigation examined the clinical features of urologic complications following obstetric and gynecologic surgery.Materials and MethodsWe accumulated 47,318 obstetric and gynecologic surgery cases from 2007 to 2011. Ninety-seven patients with urological complications were enrolled. This study assessed the causative disease and surgical approach, type, and treatment method of the urologic injury.ResultsOf these 97 patients, 69 had bladder injury, 23 had ureteral injury, 2 had vesicovaginal fistula, 2 had ureterovaginal fistula, and 1 had renal injury. With respect to injury rate by specific surgery, laparoscopic-assisted radical vaginal hysterectomy was the highest with 3 of 98 cases, followed by radical abdominal hysterectomy with 15 of 539 cases. All 69 cases of bladder injury underwent primary suturing during surgery without complications. Of 14 cases with an early diagnosis of ureteral injury, 7 had a ureteral catheter inserted, 5 underwent ureteroureterostomy, and 2 underwent ureteroneocystostomy. Of nine cases with a delayed diagnosis of ureteral injury, ureteral catheter insertion was carried out in three cases, four cases underwent ureteroureterostomy, and two cases underwent ureteroneocystostomy.ConclusionsBladder injury was the most common urological injury during obstetric and gynecologic surgery, followed by ureteral injury. The variety of injured states, difficulty of diagnosis, and time to complete cure were much greater among patients with ureteral injuries. Early diagnosis and urologic intervention is important for better outcomes.

Recovery of testicular spermatozoa from non-obstructive azoospermic patients for intracytoplasmic sperm injection (ICSI) is a recent advance in the treatment of male infertility. The purpose of this study is to identify predictive factors for sperm recovery in non-obstructive azoospermic patients. A total of 178 men with non-obstructive azoospermia had multiple testicular sperm extraction (TESE) procedures to recover spermatozoa for intracytoplasmic sperm injection (ICSI) from June 1996 to February 1999. Testicular volume, serum follicle stimulating hormone (FSH) level and testicular histology were examined as positive predictive factors for sperm recovery. Testis biopsies were categorized as severe hypospermatogenesis, maturation arrest and Sertoli cell-only syndrome based on the most advanced pattern of spermatogenesis seen on histology. Sperm retrieval success rates for the patients in three histopathological categories were compared. Spermatozoa were successfully recovered in 94 of 178 (52.8%) men. Sperm were retrieved in 13 of 80 (16.3%) with Sertoli cell-only syndrome, 15 of 24 (62.5%) with maturation arrest, and 66 out of 74 (89.2%) with severe hypospermatogenesis. Spermatozoa recovery has no correlation with testicular volume or serum FSH level. When compared against Sertoli cell-only syndrome, the odds of sperm retrieval success rate was 44.3 times higher in severe hypospermatogenesis and 8.4 times in maturation arrest. These results demonstrate meaningful correlation between successful testicular sperm recovery and testis histopathology. Only testicular histopathology can be used as a predictor of successful sperm recovery.
