Detrusor Underactivity

The aim of this clinical trial is to evaluate the effect of detrusor underactivity on the functional and symptomatic outcomes following transurethral resection of the prostate (TURP) in benign prostatic hyperplasia patients presenting with chronic urinary retention. The main questions it aims to answer are: Will they restore spontaneous voiding? They will be divided into 2 comparative groups (each group 45 patients) based on detrusor contractility. * Group (A) consists of patients with normal detrusor (bladder contractility index more than 100). * Group (B) consists of patients with underactive detrusor (bladder contractility index less than 100).

The aim of this project is to create und evaluate a multicentral, retro-/prospective database for patients with urodynamically proven detrusor underactivity (DU) or acontractility (DA) secondary to a non-neurogenic aetiology, who undergo endoscopic, anatomic enucleation of the prostate (EEP).
