Purpose
A modified version of the Clavien system has been recently suggested to allow a standardized assessment of complications associated with transurethral resection of the prostate (TURP). Aim of this multicentre study was to validate the use of this assessment tool in a contemporary cohort of patients undergoing monopolar or bipolar TURP.
Methods
Consecutive patients undergoing TURP in five Italian institutions from April 2011 to March 2012 were prospectively included in this study. Complications occurring within first postoperative month were recorded and graded according to the modified Clavien system. Univariate and binary logistic regression analysis were used for statistical analysis.
Results
Two hundred and ninety-five patients were included in the study. Overall, 47 complications were recorded in 44 patients. There was no difference in terms of postoperative complications between those who underwent monopolar TURP (27 pts; 9.2 %) versus those who underwent bipolar TURP (17 pts; 5.2 %, p = 0.142). Overall perioperative morbidity rate was 15.5 %. Most of the complications were Clavien type I (37 cases; 78 %) and II (6 cases; 12 %). High-grade complications were few as follows: Clavien type IIIb in two cases (4 %) and IV in two cases (4 %). No TURP-related deaths were reported. In the monopolar TURP group, a longer-operative time (OR 1.024; 95 % CI 1.007–1.040, p = 0.004) is an independent predictors of postoperative complications.
Conclusions
A modified Clavien system can be considered a practical and easily applicable tool in grading postoperative complications in patients undergoing TURP. Our findings confirm that TURP is a safe procedure associated with minimal perioperative morbidity.
