Purpose: To evaluate the relationship between predictive factors and urethral stricture (US) after transurethral resection of prostate (TUR-P).
Materials and Methods: We have retrospectively reviewed the data of 206 consecutive TUR-P cases by single experienced urologist. Eligible patients (n = 206) were grouped with respect to presence of US after TUR-P with cystoscopy confirmed 3 months after TURP; Group1: US positive (n = 29, 14.1%), and Group2: US negative (n = 177, 85.9%). Groups were compared with respect to descriptive data.
Results: Of 206 eligible patients, lower post-OP (maximal uroflow rate) UFRmax and lower pre-OP acute urine retention (AUR) were observed in US positive group (17.1±6.91 versus 11.37±6.50, p<0.01; 13.8% versus 35.0%, p=0.01, respectively). Other factors included age of the patient, operation time, catheter indwelling days and prostate specific antigen have no statistically significant relation to US after TUR-P.
Conclusions: Post-OP UFRmax and UFRmax deviation are predictors of post-OP urethral stricture. Pre-OP AUR is associated with post-OP urethral stricture. Our results should be supported by prospective studies including higher number of patients.
