Purpose
To investigate the effect of detrusor underactivity on the efficacy of TURP in patients with benign prostate obstruction.
Methods
A retrospective study of 350 patients with benign prostate obstruction who underwent TURP was carried out. Different degrees of bladder outlet obstruction were grouped by the bladder outlet obstruction index. ROC curves were used to calculate the optimal cut-off point for the bladder contractility index used to divide the DU patients into mild DU and severe DU patients. The effect of DU on the efficacy of TURP in benign prostate obstruction patients was studied by comparing the subjective and objective parameters preoperatively and 3 months postoperatively between severe DU, mild DU and non-DU benign prostate obstruction patients in two obstruction groups (20 ≤ BOOI < 40 and BOOI ≥ 40).
Results
According to the ROC curve, the optimal cut-off point for the bladder contractility index was 82; thus, 69 patients were considered mild DU patients (82 ≤ BCI < 100), 67 patients were considered severe DU patients (BCI < 82), and 214 patients were considered non-DU patients (BCI ≥ 100). Both the postoperative subjective and objective parameters of the non-DU, mild DU and severe DU patients significantly improved in two obstruction groups. However, in the 20 ≤ BOOI < 40 group, the successful improvement rates for the IPSS, IPSS-S, IPSS-V, QoL and fQmax in the severe DU patients were only 38.2%, 38.2%, 44.1%, 41.2% and 38.2%, respectively.
Conclusion
Patients with varying degrees of benign prostate obstruction can benefit from TURP, but for patients with severe DU in the 20 ≤ BOOI < 40 group, TURP should be considered only after deliberation.
