To evaluate the incidence of urinary tract infections (UTIs) after transurethral laser therapy of the prostate and the need for peri-operative antibiotics. One-hundred and sixteen patients (mean age 65 years, range 51-85) with benign prostatic enlargement (BPE) were treated with a Nd:YAG laser, using either the TULIP device, the Urolase fibre or the Ultraline fibre. The incidence of voiding complaints, UTIs and the need for catheterization after treatment were assessed. The first 43 patients (Group I) received no antibiotics perioperatively and the next 73 patients (Group II) received co-trimoxazole for 5 days. The patients treated using the TULIP device had more urinary complaints after treatment than those treated using the Ultraline and Urolase fibres. In Group I, 48% of the patients developed a UTI and in Group II the incidence of UTIs decreased to 30% after treatment. The incidence of UTIs was unrelated to the procedure performed. Although not statistically significant, peri-operative antibiotics tended to reduce the incidence of UTIs. Prolonged catheterization was correlated with the incidence of UTI. In Group I, patients who were treated using the Ultraline procedure had their catheter removed after a mean of 24 days, compared with 21 days for those treated with the Urolase and 19 days with the TULIP device. In Group II, the patients needed catheterization for a mean of 17 days following Ultraline treatment and 16 days following the Urolase procedure. Antibiotic prophylaxis tended to decrease the incidence of post-treatment UTIs. However, there was no clear association between the presentation and duration of complaints and the presence of UTIs.
