PURPOSE OF REVIEW: To review and summarize the current literature of the implications of obesity on nononcological urological surgery. We conducted a comprehensive search of the current literature with emphasis on the published literature in the last 18 months. RECENT FINDINGS: Over time, obese patients have become a more common encounter in clinical practice. Obesity represents a considerable operative challenge and has been linked to a higher rate of postoperative complications...

We analyzed our stone-free rates of PNL with regard to stone burden and its ratio to the renal collecting system volume. Data of 164 patients who underwent PNL were analyzed retrospectively. Volume segmentation of renal collecting system and stones were done using 3D segmentation software with the images obtained from CT data. Analyzed stone volume (ASV) and renal collecting system volume (RCSV) were measured and the ASV-to-RCSV ratio was calculated after the creation of a 3D surface volume rendering of renal stones and the collecting system...

OBJECTIVES: To investigate the anatomical relations of the papillary, infundibular and pelvic approach to percutaneous nephrolithotomy (PCNL) and evaluate the amount of vascularization at the respective sites. MATERIALS: (99m)Tc-dimercaptosuccinic acid SPECT/CT renal scintigraphies or Computerized tomographies perfusion (CTP) were performed in 40 patients (prone n=20 or supine position n=20). The angle of approach (AoA) for access tracts the respective regions of interest (ROIs) to the mid-calyceal papilla and infundibulum as well as renal pelvis were designed and compared...

INTRODUCTION: Fluoroscopy is widely used during endourologic procedures and is associated with treatment required radiation exposure. Our objective was to estimate patient radiation exposure during fluoroscopy with either a fixed table or portable C-arm using a validated anthropomorphic adult male model. MATERIALS AND METHODS: A validated male anthropomorphic model was placed supine on both a cystoscopy operating room table and a fixed fluoroscopy table unit. Metal oxide semiconductor field effect transistor dosimeters were placed at 20 organ-specific locations in the model to measure organ specific dosages...

This study aimed to assess the role of pre-designed route on computer tomography urography (CTU) in the ultrasound-guided percutaneous nephrolithotomy (PCNL) for renal calculus.From August 2013 to May 2016, a total of 100 patients diagnosed with complex renal calculus in our hospital were randomly divided into CTU group and control group (without CTU assistance). CTU was used to design a rational route for puncturing in CTU group. Ultrasound was used in both groups to establish a working trace in the operation areas...

OBJECTIVES: Mini-PCNL is a potentially less invasive technique than standard percutaneous nephrolithotomy (PCNL). We present our experience and results comparing both approaches in large burden complex renal calculi. METHODS: Prospective non randomized study comparing PCNL (24/26F nephroscope; Group A) and Mini-PCNL (15/18F; Group B) perioperative and postoperative results, in 40 (20 each group) consecutive patients between 2013 and 2014. We analyze demographic data, hemoglobin drop, urine culture, stone characteristics, operative time, puncture, number and size of the tract, disintegration energy sources, nephrostomy placement, hospital stay, stone free rate and Clavien-Dindo complications...

OBJECTIVES: Shock wave lithotripsy (SWL) remains the only effective truly non-invasive treatment for nephrolithiasis. While single-treatment success rates may not equal those of ureteroscopy and percutaneous nephrolithotomy, it has an important role to play in the management of stones. In this paper, we outline the latest evidence-based recommendations for maximizing SWL outcomes, while minimizing complications. MATERIALS AND METHODS: A comprehensive review of the current literature was performed regarding maximizing SWL outcomes...

The purpose of the study was to present our experience of retaining encrusted ureteral stents (EUS) and discuss the effectiveness of 4.5/6.5F ureteroscope (URS) in the procedure. The data of patients with EUS in our center from January 2012 to December 2016 were retrospectively analyzed. The inclusion criterion was ureteral stents that required intervention above the ureteral orifice to retain and was proved to be encrusted. Impacted stents would be removed by ureteroscope lithotripsy (URL) via 8/9.8F or 4...

OBJECTIVES: To provide a systematic review and meta-analysis of studies comparing ureterolithotripsy (URS) with percutaneous nephrolithotripsy (PCNL) or laparoscopic ureterolithotomy (LU) techniques for the management of large proximal ureteral stones (diameter greater than 10 mm). METHODS: A literature search was performed using PubMed, EMBASE, EBSCO, Web of Science, and Cochrane Library to identify suitable studies until November 2016.

Percutaneous nephrolithotomy (PCNL) is a commonly used type of minimally invasive treatment in kidney stone surgeries. Surgical success is assessed according to residual stone amount after surgery. The purpose of this study is to compare the two methods' success and practicality that are applied after the fracture of the stone in the patients who applied PCNL and which enable the removal of the residual stones. Among 102 patients who underwent a single-session of PCNL at our department between June 2015 and November 2016 were evaluated...

INTRODUCTION: Access into the collecting system is considered to be the most critical step for Percutaneous Nephrolithotomy (PCNL). AIM: The present study provides a comparative view into antegrade air pyelography and retrograde air pyelography procedures for percutaneous renal access. MATERIALS AND METHODS: A cross-sectional study was conducted on 100 patients with radiopaque renal calculi indicated for PCNL procedure. These patients were randomly assigned to two groups namely antegrade air pyelogram group (Group I) and retrograde air pyelogram group (Group II)...

Standard treatment modalities of caliceal diverticular calculi range from extracorporal shockwave lithotripsy (SWL) over retrograde intrarenal surgery (RIRS), percutaneous nephrolithotomy (PNL) and laparoscopic stone removal. A 55-year-old woman presented with a history of pyelonephritis based on a caliceal diverticular calculus. Due to the narrow infundibulum and anterior location, a robot-assisted laparoscopic calicotomy with extraction of the calculi and fulguration of the diverticulum was performed, with no specific perioperative problems and good stone-free results...
