Benign prostatic hyperplasia presenting with renal failure--what is the role for transurethral resection of the prostate (TURP)?
The aim of the study was to determine the role of transurethralresection of prostate (TURP) in normalising renal function in men presenting with obstructive renal failure secondary to benign prostatic hyperplasia. We reviewed the cases of 14 men who presented in the last 5 years with renal impairment associated with symptoms of bladder outflow obstruction and radiological evidence of obstructive uropathy. The mean serum creatinine at presentation was 632 ng/mL (range 1299 - 225). The mean age at presentation was 68.2 years (range 50 - 83 years). Duration of symptoms prior to presentation ranged between 1 - 118 months (mean 21.5 months). Following catheter insertion, all patients underwent TURP. Six of the 14 patients required dialysis prior to surgery. Histology of the resected prostate confirmed benign prostatic hypertrophy and/or hyperplasia in all cases. Patients with carcinoma of the prostate were excluded from the study. Following TURP, 2 of the 14 men (14%) failed to void spontaneously following removal of catheter - one patient performs clean self intermittent catheterization (CSIC), the other man has an in-dwelling catheter in situ. One patient died 7 months following TURP due to a myocardial infarction. However, 8 patients, (57%) remained dialysis dependent following TURP. Two of these patients have since undergone successful renal transplantation. Of the remaining 6 patients, only 3 have normal renal function with the other 3 experiencing moderately elevated serum creatinine (range 236 - 344 ng/mL). In patients presenting with renal failure due to bladder outflow obstruction, TURP restores normal voiding pattern in many cases. However renal failure due to bladder outflow obstruction tends to be more refractory and only 3 of 14 patients experienced return to normal renal function post treatment.
