Background The incidence of spina bifida (SB) is approx 1:1000, and risk of stone disease is substantially raised in SB. This is the unique published study of the outcome of patients with SB undergoing percutaneous nephrolithotomy (PCNL) compared to a neurologically intact historically matched control group at the same institution. Patients and Method A series of 96 PCNLs in 13 SB and 50 non-SB control patients was analysed. The following measurements were recorded: (1) Co-morbidities; (2) Pre-operative: (renal function, American Society of Anesthesiologists (ASA) score); (3) Intra-operative: (anaesthesia time, number of tracks, stone free rate) and (4) Post-operative: (sepsis, intensive therapy unit (ITU) and total length of stay, transfusion rate, stone composition, rate of stone disease-related nephrectomy)...

INTRODUCTION: Intrarenal inflammation has been implicated in the pathogenesis of nephrolithiasis, with prior work showing increased urine levels of IL-6, IL-8, and CCL-2 in stone patients. However, no studies have assessed for inflammation in the renal papillae. We sought to characterize novel papillary tip and urinary biomarkers in stone patients. METHODS: 92 patients with nephrolithiasis undergoing percutaneous nephrolithotomy were enrolled. Papillary tip biopsies, kidney urine, and bladder urine were collected, as well as voided urine from 8 healthy volunteers...

Purpose Nephrolithiasis is an increasingly common ailment in the United States. Ureteroscopic management has supplanted shockwave lithotripsy as the most common treatment of upper tract stone disease. Ureteral stricture is a rare but serious complication of stone disease and its management. The impact of new technologies and more widespread ureteroscopic management on stricture rates is unknown. We describe our experience in managing strictures incurred following ureteroscopy for upper tract stone disease. Materials and methods Records for patients managed at 4 tertiary care centers between December 2006 and October 2015 with the diagnosis of ureteral stricture following ureteroscopy for upper tract stone disease were retrospectively reviewed...

OBJECTIVE: Nephrostomy tubes (NT) inserted in emergency settings by interventional radiologists are frequently unsuitable for subsequent percutaneous nephrolithotomy (PCNL). We report a novel method of adjusting these NTs to be used as PCNL tracts and avoid renal re-puncture. PATIENTS AND METHODS: A retrospective search of 981 consecutive PCNLs performed in our institution between 2002-2017 identified all patients with preoperatively inserted NTs. The NTs unsuitable for PCNL were adjusted by a novel approach in which a 5-mm incision was made at the ideal puncture location (IPL) as indicated under fluoroscopic guidance...

We read with great interest the paper by York and colleagues [1] entitled "Randomized controlled trial comparing three different modalities of lithotrites for intracorporeal lithotripsy in PCNL". This study showed that the safety and efficacy of Cyberwand, Lithoclast Select, and the StoneBreaker lithotripters are similar and comparable. They stated that "the clearance rate of "hard" stones (defined as brushite, cystine, and uric acid stones) was comparable across the 3 groups). We would like to point out that this statement is one side of the coin...
