Objective This study was carried out to compare infectious complications between patients with and without a set protocol for prostate biopsy. Materials and methods Patients whom underwent prostate biopsy at our hospital from 2001 to 2012 were first identified. Two different groups of patients were then selected from 2 different years. The cut-off year in which we started to implement a standardized protocol for prostate biopsy was 2007. Data from the patient group without a set protocol were collected from January 2001 to December 2001. Data from the patient group with a set protocol were collected from January 2012 to December 2012. Results A total of 246 patients were selected from 2 different years. Ninety-two patients were collected from January to December 2001 (without set protocol). One hundred and fifty-four patients were collected from January to December 2012 (with set protocol). In the first group, the infectious complication rate was 10.75% (10/92), whereas in the second group, the infection rate was 1.3% (2/154). All minor complications (such as hematuria, hematospermia, dysuria, etc.) were self-resolving within 1 month. Most infectious complications were managed during outpatient department (OPD) hours with oral antibiotics. Only one patient required hospitalization (from 2001). None of the positive culture results revealed any resistant strain species. Conclusion The minor complications were similar in both groups and were all self-resolving. Infectious complications were more prevalent in the group without a set protocol. Adequate perioperative preparation and postoperative antibiotic regimens appear to be helpful in the prevention of infectious complications.

Background To assess the morbidities of tubeless percutaneous nephrolithotomy (PCNL) using supra-costal access and re-evaluate traditional concept of increased complications with supra-costal access. Methods From January 2010 to December 2014, a single surgeon performed 118 consecutive one-stage fluoroscopic guided PCNL’s for complex renal and upper ureteral stone. Our definition for complex renal stone is defined as partial or complete staghorn stone, multiple renal stones in more than 2 calyxes, obstructive uretero-pelvic stone > 2 cm, and a renal stone in single functional kidney. Inclusion criteria include: staghorn stones, renal calculi > 2 cm in diameter, upper ureteral stone > 1.5 cm in diameter. Exclusion criteria for tubeless PCNL include: significant bleeding or perforation of the collecting system, large residue stone, multiple PCNL tract and obstructive renal anatomy. Morbidity, operation time, analgesia requirement, length of hospital stay, stone- free rate, were analyzed. Results Of the 118 consecutive PCNL, eighty-six patients underwent tubeless PCNL (56 supra-costal and 30 sub-costal) and included in our prospective follow-up period. The mean age, operation side, stone locations were similar. The male to female ratio is higher in supra-costal than sub-costal. Large renal stones and staghorn stones makes up for most patients (supra-costal: 75%, sub-costal: 80%). The stone–free rate of supra-costal group was 59% (33/56) and in sub-costal group was 50% (15/30). The operative times, length of stay, post-op analgesic use, hematocrit change was similar in both groups. The overall complication rate is 6% [supra-costal (1/56), sub-costal (4/30)] with the majority being infectious complications. Conclusions Supra-costal access above 12th rib during tubeless PCNL is safe and effective procedure and is not associated with higher incidence of post-op complications in experience hands.

s / Urological Science 26 (2015) 294e300 295 (p< 0.02) which was poor performance in facets of overall QoL(0.046), enjoying of life(p1⁄4 0.001), meaning of life(p1⁄4 0.01), time for leisure activity(p1⁄4 0.002). However, log of PSA showed lack of impact in QoL. Conclusion: Our data demonstrated the PSA values and trend of PSA value play an important role in determining QoL in Taiwanese PC patients. Which could provide information for clinician in decision making. The underlying reason is worth to explore in future.

Objective This study was conducted to investigate the safety and feasibility of self-retaining barbed absorbable suture application in laparoscopic partial nephrectomy (LPN). Materials and methods From January 2010 to September 2014, 38 cases of LPN were performed at Changhua Christian Hospital, Changhua, Taiwan. The patients were divided into two groups: the nonself-retaining barbed suture (non-SRBS) group ( n = 21) and the SRBS group ( n = 17). There was no significant difference in age, RENAL (Radius, Exophytic/Endophytic properties, Nearness of the tumor to the collecting system or sinus, Anterior/Posterior, Location relative to polar lines) nephrometry score, and tumor type between the two groups. Clinical data and outcomes were analyzed retrospectively. Results All 38 cases of LPN were successfully performed, without conversion to open surgery or serious intraoperative complications. In the SRBS group, renorrhaphy time and length of hospital stay were significantly shorter than those of the non-SRBS group ( p = 0.015 and p = 0.009, respectively). Conclusions The application of SRBS in LPN could shorten renorrhaphy time and hospital stay with good safety and feasibility.
