Hakkı Uzun, Nezih Akça
Objectives: To compare the 7.5-9.5F ureteroscope (URS) with the 4.5-6.5F URS (Ultra-Thin) in terms of success and complication rates in adult patients with ureteric and renal pelvic stones. Patients and methods: In all, 41 patients treated with 7.5-9.5F semi-rigid URS (Group 1) and 33 patients treated with the Ultra-Thin (Group 2) were prospectively included in the study. All patients underwent holmium laser ureteroscopic lithotripsy. In each group, when the selected ureteroscopic intervention failed to reach or disintegrate the stone, the URS was replaced with the other one...

PURPOSE OF REVIEW: Established guidelines provide recommendations on the management of kidney stones to prevent recurrence. However, clear and clinically useful terminology for recurrence of kidney stones is needed. This review describes the various manifestations of kidney stone recurrence and the reported rates of kidney stone recurrence in various clinical settings. RECENT FINDINGS: Kidney stone recurrence has a wide range of symptomatic and radiographic presentations...

Introduction: Managing upper ureteral stones with shock wave lithotripsy (SWL) has been done for many years. However, no conclusive data have been found on the intervals required between repeated SWL sessions. Aim: To identify the most optimal intervals between SWL sessions. Material and methods: Between September 2015 and December 2016, 80 patients undergoing elective outpatient lithotripsy who required repeated SWL sessions for ureteral stones were evaluated...

Objective: While small non-obstructive stones in the adult population are usually observed with minimal follow-up, the same guidelines for management in the pediatric population have not been well-studied. We evaluate the clinical outcomes of small non-obstructing kidney stones in the pediatric population to better define the natural history of the disease. Methods: In this IRB-approved retrospective study, patients with a diagnosis of kidney stones from January 2011 to March 2017 were identified using ICD9 and ICD10 codes...

Here we define precision medicine approaches and discuss how these may be applied to renal stone-formers to optimise diagnosis and a management. Using the gene discovery of monogenic stone disorders as examples, we discuss the benefits of personalising therapies for renal stone-formers to provide improved prevention and treatment of these disorders.

Purpose To explore regional adoption of URS over SWL in the state of California (CA) and to identify factors associated with this adoption over time. Materials and Methods We used the California Office of Statewide Health Planning and Development (OSHPD) public data to identify URS and SWL procedures performed for renal and ureteral stones from 2005-2016. The level of analysis was the region wherein each procedure was performed, defined by the 19 California labor market regions. OSHPD data were supplemented with the Area Health Resource File to provide information on regional characteristics...

BACKGROUND: Urolithiasis is a worldwide problem  due to its high prevalence and  recurrence. Percutaneous nephrolithotomy is a minimally invasive surgical option for the treatment of large renal stone burden greater than 20mm, staghorn calculi and lower pole calyceal stone greater than 10 mm. The objective of this study was to evaluate the safety and  efficacy of percutaneous nephrolithotomy in the management of lower pole calyceal stones. METHODS: Seventy  patients who presented in between June 2013 and September 2017 with  lower pole calyceal stones and lower calyceal stones with pelvic extension  were included in the study...

BACKGROUND: The prevalence of urolithiasis is nearly 20% and patients with urolithiasis constitute an essential part of the patients referred to the urology clinic. Many parameters should be considered for the management of renal stones and authors recommend extracorporeal shockwave lithotripsy (SWL), retrograde intrarenal surgery (RIRS), and percutaneous nephrolithotripsy (PNL), as treatment options. Among these techniques, SWL does not require general anesthesia, has 89% success rate for renal pelvic stones: 83% for upper caliceal stones, 84% for middle caliceal stones, and 68% for lower caliceal stones...

PURPOSE: The miniaturization of instruments has had an impact on stone management. The aims of this study were to highlight surgeon preferences among Retrograde Intra Renal Surgery (RIRS), Regular, Mini-, UltraMini- and Micro- Percutaneous Nephrolithotomy (PCNL) for urolithiasis and to compare the effectiveness and safety of these techniques in a real-life setting. METHODS: A 12-item survey regarding endourological techniques was conducted through Survey Monkey among attendees of the 2013 European Association of Urology Section of Urolithiasis meeting...

22-year-old male patient with irrelevant medical history presented with bilateral renal stones; multiple stones in right renal pelvis measured 10, 11, and 11mm and another one on the left side measured 12mm. Extra corporeal shock wave lithotripsy (ESWL) was done first on the left side, but after 400 shocks and total energy of 20 Storez Medical Lithotripsy Index only, the stone wasn't visible. Then, the operator switched to the right side and a he completed the session. A day after, the patient presented with bilateral renal colic, gradual rising of renal function and imaging showed bilateral steinstrasse with bilateral hydroureteronephrosis...

Introduction: Defect in ureteral continuity can be due to various etiologies. The surgical options for management of complex long-segment ureteric defects are limited. Use of ileum is indicated in these cases; however, the technique is challenging and outcomes need to be assessed in detail. Material and Methods: It is an observational study conducted over 4 years. After preoperative optimization, ureteric reconstruction was performed using standard techniques of ileal interposition in cases of unilateral and bilateral long-segment ureteric defects...
