IMMEDIATE UROFLOWMETRY AFTER TRANSURETHRAL RESECTION OF PROSTATE: DOES IT HELP IN PREDICTING OUTCOME OF SURGERY.

Introduction and Objective: To evaluate the role of immediate uroflowmetry in patients of benign prostatic hyperplasia following transurethral resection of prostate.Methods:100 patients were included in our study who underwent TURP at our centre. Complete preoperative evaluation was done which included usg prostate, uroflometry and IPSS scoring. Uroflometry was done immediately at the time of catheter removal and after one and three month of surgery. Qmax, IPSS scoring were compared before and after TURP. Result: The mean patient age in study was 64.52 years. Mean Qmax, AFR and prostate weight were 8.30 ? 3.26 ml/sec, 4.82 ? 1.72ml/sec and 46.62 ? 31.10 gms respectively. Of the 100 patients, 75% patients were having immediate Qmax >15ml/sec and 25% were having <15 ml/sec. On comparing the mean value of different parameters between these two groups it was found that the difference between parameters were not statistically significant. Sensitivity and specificity of immediate uroflowmetry (Immediate Qmax ) were 91.3% and 61.3 % respectively. Positive predictive value of this test was 84% and the negative predictive value was 76%. Conclusion: Based on our experience, we conclude that immediate uroflowmetry after TURP can be used as a tool to predict the outcome of TURP up to three months after surgery with good accuracy but can these results be reciprocated on longer follow up need to be evaluated and can immediate uroflowmetry be used as a tool to differentiate those patients which are more likely to get re operated in the future need to be studied. For answering these questions further studies in the same direction with longer follow up period needed to be done.
