Introduction: TURP complications significantly contribute for morbidity and hospital stay. Our objective was to prepare a score which can predict this complications preoperatively and help to take measures to reduce them. Methods: A Prospective observational study was conducted.In the study variables used were- age, associated co morbidity (calculated by ASA–PS criteria), prostate size on USG, duration of treatment with 5-? reductase inhibitors, serum PSA.Outcome variables measured were peri-operative bleeding, failed post catheter free trial, post operative electrolyte abnormality, long hospital stay and transient stress urinary incontinence. Each of study variables, based on their distribution were divided in to tertiles. The minimum value of the score being 5 and maximum 15. Based on the above findings we developed a scoring system as shown in Table.1 and an individual score was developed for each patients. Table 1: Variables SCORE 1 SCORE 2 SCORE 3 Age 58-64 65-73 =74 PSA =2.59 2.60-4.59 =4.6 Prostate size in (cc) 35-47.99 48.00-60.99 =61 5a Reductase inhibitor (in weeks) 0-1 2-4 =5 ASA 1 2 3 Results: We analyze 110 patients. Complications were bleeding in 11(10.2%), electrolyte imbalance in 31 (29.5%),failure of catheter free trial in 5(4.8%), longer hospital stay in (26)25.7% and transient sress urinary incontinence in 6(5.7%) patients were present. Factors and complications showed significant relation.The factors significantly associated with complications in Bivariate analysis were PSA value (p- 0.008), age (p-0.049),prostate size (p- 0.001),5alpha reductase (p- 0.042) and not significant was ASA (p-0.431).Based on these findings we categorize patients in to three categories as CAT I with score of 5-7, CAT II with score of 8-11 and CAT III with a score of 12-15.The categorization predict the peri-opeartive complications according to groups so that effective measures can be taken before hand of the procedures. The sensitivity and specificity of the scoring system is as shown in below table. Table 2: CATEGORY Sensitivity Specificity CAT I (5-7) 89 23 CAT II (8-12) 17 97.6 CAT III (12-15) Very low ?100% Conclusions: Our proposed scoring system based on the common pre operative parameters to predict the peri operative complication rate is easy to use which can reduce the morbidity of the patients.
