Impact of Postoperative Pyuria on Treatment Outcomes After PVP

Does Postoperative Pyuria Influence Treatment Outcomes After Photoselective Vaporization of the Prostate (PVP)?: A Short-term Serial Follow-up Study

The aim of this study was to identify serial changes in the incidence of postoperative pyuria after the Photoselective Vaporization of the Prostate (PVP), to determine whether the presence of postoperative pyuria could be correlated with surgical outcomes after surgery and to identify predicting factors that influence on persistent pyuria after the PVP.

Inclusion Criteria:

• men who underwent photoselective vaporization (PVP) using 80 watt potassium-titanyl-phosphate (KTP) laser or 120 watt high-power-system (HPS) laser for benign prostatic hyperplasia refractory to medical treatment
• sterile urine on urinalysis and urine culture before surgery
• absence of indwelling urethral catheter before surgery

Exclusion Criteria:

• previous diagnosis of prostate carcinoma or bladder cancer
• co-existence of urinary stone
• any antibiotic treatment within 2-weeks before surgery
