Abstract:
Objective To explore the availability and safety of conducting low-pressure TURP assisted by a home-made cystometry and warning system.Methods 167 benign prostatic hyperplasia (BPH) patients admitted from Jan 2014 to Jan 2016 were randomly assigned into cystostomy group (group A) and non-cystostomy group (group B). In group A (n = 85), 42 patients (group A1) were performed percutaneous cystostomy + TURP, and 43 (group A2) were performed continuous flushing sheath TURP. In group B (n = 82), 42 patients (group B1) were received percutaneous cystostomy + TURP, and 40 (group B2) were received continuous lfushing sheath TURP. In group A, bladder pressure was monitored in real time with a cystometry and was monitored by bladder puncture using a home-made siphon, ensuring low bladder pressure throughout TURP. Serum Na+ levels were measured before and after operation in all four groups. The operation time, the intraoperative bleeding, the weight of resected prostates and the time before which urine turned clear were recorded. The IPSS, maximum lfow rate (Qmax), postvoid residual volume (PVR) and life quality score (QOL) were evaluated.Results While no significant differences were found between group A1 and A2, there were significant differences between group B1 and B2, indicating cystostomy group was safer than non-cystostomy group. When compared group A1 with B1, or group A2 with B2, it showed that the safe operation time to perform prostate tissue resection was longer in cystostomy group; the weight of the resected prostates was heavier; the time before which urine turned clear were shorter; and the IPSS improvement was better. These findings presented better therapeutic effects in cystostomy group than in non-cystostomy group.Conclusions This home-made cystometry and warning system could timely detect high bladder pressure state during TURP, making it possible to avoid of high pressure, ensuring low bladder pressure lfushing during the operation, lengthening the safe operation time, increasing tissue resection ratio, reducing transurethral resection syndrome, thus helping TURP to be safer.
