Background: Difficult voiding in men can largely be found in detrusor hypo-contractility or bladder outlet obstruction (BOO); still, physicians may miss that both can happen together when only UDs are considered. Initially, there is still no common agreement regarding the urodynamic criteria for diagnosing detrusor hypo-contractility. The purpose of was to evaluate the change in Qmax after treatment with transurethral surgery for benign prostatic hyperplasia.
Methods: A quasi-experimental study was conducted over six months (from May 4 to November 4) at the Department of Urology, SIMS, using a non-probability consecutive sampling technique. A total of 78 patients with BPH underwent TURP (transurethral resection of prostate). Urodynamic assessments measured bladder function using the DUET® LOGIC G2 system, with BCI <100 as the inclusion criterion. TURP was performed under spinal anesthesia, and postoperative Qmax changes were evaluated at three months. Data were analyzed using SPSS version 22, with statistical significance set at p ≤ 0.05. The study assessed TURP outcomes in patients with detrusor underactivity.
Results: The International Prostate Symptom Score (IPSS) was used to assess symptom severity. The mean IPSS (International Prostate Symptom Score) score before and after 3 months of procedure was 25.24 ± 1.95 and 9.91 ± 3.38, respectively (p < 0.001). The mean residual urine output before and 3 months of procedure was 104.21 ± 14.46 and 49.08 ± 17.57. The mean Q-max before and after 3 months of procedure was 7.08 ± 1.48 and 15.64 ± 3.52, respectively. The mean change in Q-max after 3 months was 8.56 ± 2.10.
Conclusion: The study concluded that men with an enlarged prostate and a weak detrusor muscle should consider TURP when medical treatment does not work well for them.
