OBJECTIVE: To assess urinary flow rate/uroflowmetry in patients undergoing transurethral
resection of the prostate (TURP) for benign prostatic hyperplasia (BPH), during three postoperative
STUDY DESIGN: Prospective observational study.
MATERIALS AND METHODS: This study was conducted at Department of Urological Surgery
and Transplantation, Jinnah Postgraduate Medical Centre (JPMC) Karachi-Pakistan, between
March 2002 and March 2005. Fifty consecutive clinically diagnosed cases of BPH who never
went in retention of urine and underwent TURP were included in this study. Preoperative urinary
flow rate was measured. Uroflowmetry was postoperatively carried out after every month for
three months period and observations were analysed.
RESULTS: Mean±SD age of the subjects was 63.62±6.75 years. Preoperatively mean±SD values
were maximum flow rate 7.60±2.41 ml/sec, average flow rate 4.44±1.28 ml/sec and voided volume
165.54±49.60 ml. Post-TURP mean±SD values after three months were maximum flow rate
27.24±5.11 ml/sec, average flow rate 13.48±2.08 ml/sec and voided volume 240.32±49.91 ml. The
variation in means of uroflowmetry parameters from first to third post-TURP month found statistically
BPH, uroflowmetry, TURP.
