Extracorporeal shock wave lithotripsy as first line treatment alternative for urinary tract stones in children: A large scale retrospective analysis

Purpose: Management of urinary tract stones in children represents a challenging problem. In this study we retrospectively analyzed our experience with extracorporeal shock wave lithotripsy (SWL) in children

Tubeless percutaneous nephrolithotomy: Can be a choice, why not?

Percutaneous nephrolithotomy (PCNL) has been widely accepted and is commonly used to treat renal calculi. The optimal drainage of kidney after PCNL has not been clearly determined yet. Placement of an 18F to 24F nephrostomy tube at the end of the procedure is accepted as standard of care to date. The main advantages are adequate renal drainage, hemostatic tamponade and providing renal access for second look PCNL. However, based on the concept that the purpose of the tube is only to maintain adequate drainage of the kidney, a "tubeless" approach has been developed by placing a ureteral stent or catheter to provide drainage after PCNL instead of a nephrostomy tube. Tubeless PCNL is an effective and safe procedure for treatment of renal stones in selected cases. This procedure can even be chosen for patients with previous renal surgery, and hemorrhagic tendency. By using this method, less postoperative pain and a shorter hospital stay can be achieved, when compared with conventional PCNL. There is a controversy over ideal drainage system after PCNL in recent years. Herein, we made a systematic review for efficacy and safety of tubeless PCNL, totally tubeless PCNL, discussed different variations and compared the outcomes of this technique with standart PCNL. © Karadag et al.; Licensee Bentham Open

Calcified double J stent after sequential liver and renal transplantation associated to primary oxalosis: Case report

Hyperoxaluria type I (HPI) is a metabolic disorder secondary to liver alanine glyoxylate aminotransferase deficiency. Renal failure occurs due to the excessive production and precipitation of oxalate in the kidney. Combined liver-renal transplantation is the correct treatment for this condition when end-stage renal failure occurs since in renal transplantation alone the risk of recurrence of the same pathology in the transplanted kidney would be high. We determined the calcification surrounding the double J stent inserted to the transplant ureter in a short time in a 22-year-old patient who underwent sequential liver and renal transplantation with the diagnoses of oxalosis. In the literature we have not found papers on calcification of double J stent following combined or sequential transplantation. Although after the sequential transplantation the calcification, nephrocalcinosis, and renal stones were practically not of great concern, these patients should be followed up more carefully in terms of stent calcification during the early post-transplant period
