Correlation between detrusor pressure and transurethral resection of prostate outcome / 中华泌尿外科杂志

ABSTRACT

Objective To assess the long-term outcome of transurethral resection of the prostate (TURP) in men with different maximum detrusor pressure (Pdet.max).Methods 113 neurologically intact men diagnosed with BPH and undergone surgical intervention in our department were enrolled between Feb.2009 and May 2012.All patients had completed the International Prostate Symptom Score (IPSS) and quality-of-life (QOL) questionnaires and had undergone a full urodynamic analysis before surgery.The outcomes were assessed at 24 months postoperatively using the IPSS score,QOL score,and maximum urinary flow rate (Qmax).Results After 24 months follow-up,3 cases in the poor symptom improvement group could not void.The average Pdet.max of these three patients was (15.7±5.1) cmH2O,which was statistically significantly lower than that of the other three groups [(102.7±39.3),(95.9±42.8),(77.0±27.4) cmH2O] (P＜0.05).Nine cases in the poor functional improvement group whose average Pdet.was (32.5± 16.6) cmH2O,which was statistically significantly lower than that of the other three groups [(115.2±36.3),(87.5±28.7),(75.5±46.9) cmH2O] (P＜0.05).Conclusions Urodynamic analysis plays an important role in judging the efficacy of TURP.Patients with a Pdet.max less than 32.5 cmH2O may not have an objectively successful result from surgery treatment.
