The Safety and Efficacy of Addition of Gentamicin on Irrigation Fluid in Prevention of Post-Transurethral Resection of the Prostate Infectious Complications.

220 patients scheduled for TURP for the management of urinary retention or LUTS will be included and divided into two groups; "Group A" includes 110 patients who will undergo TURP with addition of one ampoule of gentamicin 80 mg (2ml) /3L of irrigation solution (the first 9 Liters during resection and the first 6 Liters during post-operative irrigation) and "Group B" includes 110 patients who will undergo TURP with addition of normal saline (2 ml) as a placebo on the irrigation solution. Determination of Gentamicin in human serum using HPLC/UV after Chemical Derivatization will be done using the method of Barends et al (Barends, Brouwers, \& Hulshoff, 1987). Both groups will be compared as regards the demographic data, post-operative pyuria and bacteruria (1 week after removal of urethral catheter), fever, and/or sepsis.
