Abstract
PURPOSE: We aimed to evaluate the outcome of transurethral resection of the prostate (TURP) in patients with benign prostatic hyperplasia (BPH) and diagnosed to have weak detrusor contractility by urodynamic study. METHODS: A prospective study of 32 male patients had BPH candidate for TURP diagnosed to have impaired detrusor contractility by preoperative urodynamic study. We studied the postoperative outcome after TURP regarding international prostate symptoms score (IPSS), maximum flow rate (Qmax), post-voiding residual urine (PVR), the patients need for catheter, and urodynamic pressure flow study (PFS) parameters (maximum detrusor contractility, bladder contractility index (BCI), maximum bladder capacity and compliance) after 6 month follow-up. RESULTS: Twenty-one cases presented with urethral catheter because of chronic or refractory retention. Twenty patients voided preoperatively during PFS with mean detrusor pressure (Pdet) at Qmax 23.97 ± 25.54 cmH2O and the mean BCI was 51.04 ± 23.86, while twelve patients did not void with mean maximum Pdet 21.75 ± 7.34. After 6 month follow-up, there was significant improvement in IPSS, Qmax, and detrusor contractility (Pdet at Qmax and BCI) postoperatively in all patients, and there was no significant postoperative improvement of post-voiding residual urine (p value 0.92). Finally, 11 patients voided normally without RU, 7 patients needed timed triple voiding with crede maneuver and small RU, and 14 patients needed CIC. CONCLUSIONS: There were significant improvements in IPSS, detrusor contractility, and urine flow after TURP in patients with BPH and weak bladder contractility, although the risk of postoperative urine retention in approximately 43% of cases and needed CIC.
