Optimal patient position for percutaneous nephrolithotomy in horseshoe kidneys: Traditional prone or supine?

OBJECTIVE: Although it was stated that supine percutaneous nephrolithotomy (PCNL) was associated with relatively shorter surgical times and comparable success and complication rates, there is no consensus in the current literature concerning the safety and efficacy of supine PCNL in patients with horseshoe kidneys. We aimed to compare supine and prone PCNL regarding safety and efficacy in patients with horseshoe kidneys. METHODS: Data of the patients with horseshoe kidneys who underwent PCNL for renal stones larger than 2 cm between January 2010 and May 2021 were retrospectively reviewed. The study patients were categorized as Group 1 (i.e., supine PCNL-SPCNL) and Group 2 (i.e., prone PCNL-PPCNL). Both groups were compared regarding demographic, clinical, and surgical data. RESULTS: Sixty-five patients were included. Among these patients, 31 (47.7%) were in Group 1, while 34 (52.3%) were in Group 2. Both groups were statistically similar in terms of demographic data, stone characteristics, perioperative parameters, and complication rates (p > 0.05). There was no statistical difference in terms of additional treatment rates, stone-free rates in the postoperative second-day and third-month evaluations (p > 0.05). Mean surgical time was significantly longer in Group 2 (113 ±â€¯17.1 min) than in Group 1 (90.6 ±â€¯11.3 min) (p = 0.000). CONCLUSION: Although it is traditionally performed in the prone position, the supine approach is as safe and effective as the prone approach. In addition, the supine approach is associated with significantly shorter surgical times.

Does time elapsed between urine culture and retrograde intrarenal surgery affect the rate of systemic inflammatory response syndrome?

OBJECTIVE: To identify the preoperative and intraoperative factors that might cause systemic inflammatory response syndrome (SIRS) after retrograde intrarenal surgery (RIRS), and to investigate the effect of time elapsed between the date of performing preoperative bladder urine culture (PBUC) and surgery date on postoperative SIRS. MATERIALS AND METHODS: Four hundred sixty-seven patients who had RIRS between January 2013 and June 2020 constituted the target population of this study. PBUC were obtained from all patients before undergoing surgery. Postoperatively, patients were closely monitored for fever and other signs of SIRS. Univariate and multivariate logistic regression analysis were performed to reveal the predictive factors for SIRS after RIRS. RESULTS: The entire study cohort consisted of 467 patients. The rate of SIRS was 5.6%. In univariate analysis, the rate of DM, recurrent urinary tract infection (UTI) history, surgical time, and stone burden were significant predictive factors for SIRS. In multivariate analysis, the rate of recurrent UTI history, surgical time and stone burden were observed to be statistically significant predictive factors. Time elapsed between the date of performing PBUC and surgery date was not different between the SIRS group and the normal group. CONCLUSION: We conclude that the time between the date of performing PBUC and surgery date is not an influential factor for SIRS. Clarifying this issue with prospective studies may be useful, as endourologists frequently encounter this situation in daily practice.

Testicular torsion in spinal cord injury: a case report.

STUDY DESIGN: Case report. OBJECTIVE: To describe a case of testicular torsion in spinal cord injury (SCI). SETTING: Physical Medicine Rehabilitation Training and Research Hospital in Turkey. METHODS: We present the first case of testicular torsion in SCI along with its clinical presentation and follow-up results. RESULTS: Testicular torsion is a rare condition. No case was reported in people with SCI so far. The main difficulty in the diagnosis is that the nociceptive pain is below the injury level and the acute condition could be overlooked. CONCLUSION: Testicular torsion is an acute condition for which early diagnosis is critical in the treatment. The case we describe adds new pitfalls in the diagnosis of this rare condition in people with SCI from the perspective of nociceptive pain below the injury level.
