BACKGROUND: Patients with benign prostatic hyperplasia (BPH) suffering from hypocontractile detrusor were generally regarded unsuitable for surgery. This prospective study is to evaluate the efficacy of transurethral resection of the prostate (TURP) on BPH patients diagnosed detrusor hypocontractility on urodynamic study (UDs).
METHODS: Twenty patients were included in the study with mean age of 74.20 ± 7.93 years (range: 57-88). Outcomes were determined by patients' self-assessment questionnaires, International Prostate Symptom Score (IPSS) and Quality of Life (QoL), and UDs parameters including maximum uroflow rate (Qmax), postvoid urine volume (PVR), bladder compliance, maximal cystometric capacity (MCC), and maximum detrusor pressure (Pdetmax).
RESULTS: Median follow-up duration was 12 months (range: 10-16). After TURP, IPSS/QoL, Qmax, PVR, and Pdetmax were significantly improved and there were no significant differences with regard to bladder compliance and MCC.
CONCLUSION: UDs may play a very limited role in detecting bladder outlet obstruction (BOO) in BPH patients with hypocontractile detrusor. TURP may obtain a promising effect on such patients with unidentified BOO. These patients should not be arbitrarily excluded from surgical indications simply based on UDs findings.
