TRANSURETHRAL INCISION/RESECTION OF THE PROSTATE (TUIP/TURP) IN OPERATIVE TREATMENT OF REPEATED BLADDER OUTLET OBSTRUCTION EARLY AFTER KIDNEY TRANSPLANTATION

The aim of the study was to assess the incidence and etiology of repeated bladder outlet obstruction (BOO) after kidney transplantation and to analyze the results of transurethral incision of the prostate/transurethral resection of the prostate (TUIP/TURP) in the early period after kidney transplantation. The study included 24 male patients having undergone renal transplantation and early transurethral surgery for BOO in our institution between 2005 and 2011. TUIP or TURP was performed depending on the etiology of BOO. The indications for transurethral surgery were repeated urinary retention despite therapeutic attempts with alpha-receptor antagonists, or repeated residual urine with renal transplant dysfunction and/or consequent urinary tract infection. Preoperative assessment included past medical history, clinical examination, PSA, volume of residual urine estimated with ultrasound, and urinary culture. Among 345 male patients having undergone renal transplantation, repeated BOO was noted in 24 patients. TUIP was performed in 19 and TURP in five patients. The mean age of our patients was 52 (range, 33-73) years and the mean time on dialysis 7.43),ears (range, 4 months to 25 years). The procedure was performed on the mean of day 16 (range, 14-29) after transplantation and urethral catheter was removed on the mean of day 3.3 (range, 2-9) after the procedure. The etiology of BOO was bladder neck contracture in nine and benign prostatic hyperplasia in 15 patients. In all patients, surgical procedures were performed without any complication. Restoration of urinary bladder function was complete in all patients. In conclusion, early transurethral treatment of repeated BOO is a safe procedure with excellent results following renal transplantation.
