Prostatic Diseases and Male Voiding DysfunctionDoes Postoperative Leukocyturia Influence Treatment Outcomes After Photoselective Vaporization of the Prostate (PVP)? A Prospective Short-Term Serial Follow-Up Study
Section snippets
Patients and Methods
This study was approved by the Institutional Review Board of our hospital. A total of 102 eligible men, who underwent PVP using an 80 W potassium–titanyl-phosphate (KTP) laser (n = 90) or a 120 W high-performance system (HPS) laser (n = 12) for LUTS and/or BPH refractory to medical treatment between March 2010 and January 2014, were included in this prospective study. The inclusion criteria were: (1) no leukocyturia on baseline urinalysis and (2) sterile urine culture before surgery. Patients
Results
The baseline characteristics of the patients are shown in Table 1. Total IPSS, subtotal voiding symptom score, and the QOL index decreased significantly beginning 1 week after surgery compared with those at baseline, whereas the subtotal storage symptom score and total OABSS score decreased significantly beginning 3 months after surgery (Fig. 1). Maximum flow rate, PVR, and BVE improved significantly beginning 1 week after surgery, compared with those values at baseline (Fig. 1). The mean
Comment
Postoperative leukocyturia is a relatively common finding during the early postoperative period after transurethral BPH surgery. Some patients complain of bothersome LUTS, including dysuria and storage symptoms after PVP. Cho et al suggested that the duration of leukocyturia after TURP is significantly associated with the duration of postoperative LUTS, such as dysuria or storage symptoms.2 It has been presumed that leukocyturia after TURP is associated with exudation of inflammatory cells from
Conclusions
Postoperative leukocyturia is observed in all patients immediately after PVP, but its incidence decreases with time. However, the postoperative leukocyturia and the related dysuria may have an adverse effect on treatment outcome during the early postoperative period after PVP. Also, our data suggest that preoperative older age, higher serum PSA level, larger prostate size, and a greater amount of energy utilized may be risk factors of persistent leukocyturia at 3 months after PVP.
