OBJECTIVE: Percutaneous nephrolithotomy is a well-established procedure for the management of urinary calculi and can be performed intercostally or subcostally. Favoring one approach versus the other is still debatable and literature has been inconclusive regarding the efficacy and safety of both approaches. Hence, this study aims to assess the safety and efficacy of direct non-angled intercostal technique performed under full expiration and to compare it to the subcostal approach. METHODS: PCNL was conducted among 361 patients during 2010-2015 at Saint George Hospital University Medical Center in Beirut, Lebanon...

Wayland J Wu, Zeph Okeke
Percutaneous nephrolithotomy has become the preferred treatment modality for patients with large renal calculi. The technique provides excellent stone clearance, but complication rates are higher than those of minimally invasive techniques, such as ureteroscopy and shockwave lithotripsy. Guy's stone score, S.T.O.N.E. nephrolithometry, the CROES nomogram, and S-ReSC are contemporary scoring systems introduced to provide standardized grading of stone complexity and outcomes of percutaneous stone surgery. Guy's stone score is easy to apply and has been validated in multiple studies...

While the effects of percutaneous nephrolithotomy (PCNL) on patients with normal functioning kidneys have been widely studied, the outcomes of PCNL in populations with renal insufficiency remains under reported. We aimed to examine the literature and evaluate the efficacy and safety of PCNL in this non-indexed patient group. A systematic search was performed in accordance with Cochrane guidelines. This served to identify original studies investigating PCNL carried out in the adult population with chronic kidney disease published over the past 20 years (since 1997)...

We report 3 different cases in which ultrasound-guided percutaneous cryoneurolysis was performed to treat acute pain: 1 patient with refractory incisional pain after percutaneous nephrolithotomy; 1 patient with burns to the foot; and 1 patient with pain from iliac crest grafting. Acute pain associated with surgery or injury is a challenge to treat with local anesthetic-based regional anesthesia techniques when the anticipated pain duration exceeds a few days. Cryoneurolysis is an alternative analgesic method that utilizes extremely cold temperatures to reversibly ablate peripheral nerves and is potentially a novel method for acute pain management...

OBJECTIVE: The objective of this study is to evaluate our methods for management of renal caliceal diverticular stones (CDS). MATERIALS AND METHODS: We conducted a retrospective study from January 2005 to July 2015 and included patients who were treated for renal CDS. Patients were evaluated for treatment modality, puncture site (in case percutaneous nephrolithotomy [PCNL] attempted), operative time, stone clearance rate, and complications. During PCNL, if the infundibulum was found to connect the diverticulum to the calyx, then a double J stent was placed...

Silicate urolithiasis is rare in humans (0.2%) but common in herbivorous animals. We report a previously unreported instance in India where a pediatric patient with renal pelvic calculus who underwent percutaneous nephrolithotomy was found to have silicate urolithiasis on stone analysis. Retrospective analysis did not reveal any risk factors associated with silicate stone formation.

Background: A rare percutaneous nephrolithotomy (PCNL) complication and its management is reported. Case Presentation: A male patient, 43 years of age, underwent PCNL for a large left pyelocaliceal stone. Surgery was performed in the Valdivia-Galdakao supine position. The percutaneous tract was established by combined radiologic and sonographic guidance. The tract was dilated by balloon and a 24F Amplatz sheath was located. As complete clearance was not achieved because of a residual lower pole caliceal stone, a ureteral Double-J and a 20F nephrostomy were located for a second-look PCNL through the same tract after 7 days...

INTRODUCTION: Miniaturization of instruments has changed the paradigms of percutaneous nephrolithotomy (PCNL). To date, however, few studies have analyzed the possible renal trauma generated by PCNL tract dilation. The purpose of this study is to evaluate and compare systematically the renal injury of all PNCL dilation techniques in pork kidneys (PK) and cadaveric kidney models (CK). MATERIAL AND METHODS: Twelve dilation devices were tested (from 4.8 to 30 French (Fr)) including micro- and mini- PCNL kits, the Alken dilation set, 20 and 30 ATM balloons and the Amplatz set...

INTRODUCTION AND OBJECTIVES: Although extracorporeal shock wave lithotripsy (ESWL) is the first choice for pediatric renal calculi <2 cm, the success rate after the first session is low. This is in contrast to other minimally invasive procedures like percutanous nephrolithotomy (PCNL) and retrograde intrarenal surgery (RIRS), which have higher rates of success. Therefore, the present study sought to identify predictors of success after one session of ESWL. PATIENTS AND METHODS: A prospective study including 100 children with renal stone burden <2 cm who underwent ESWL at the present institution...
