OBJECTIVE To review our experience of PCNL in horse shoe kidneys. METHODS Between June 2001 and January 2005 we performed PCNL in 16 Horse shoe kidneys in 14 patients with calculi, 2 patients had bilateral calculi. Percutaneous puncture was made with patient in prone position. Their ages ranged between 4 to 52 years with a mean age of 26.3 years. Our mean stone burden was 820 mm2 (range 40-13...

Laparoscopically assisted percutaneous transperitoneal nephrolithotomy has been described to decrease the risk for the bowel injury.(3) There are serious limitations to PCNL. The Amplatz sheath is inserted dorsally near the iliac crest, which restricts free movement of the nephroscope and may damage retroperitoneal nerves. Alternatively, laparoscopic transperitoneal and retroperitoneal pyelolit...

introduction percutaneous nephrolithotomy (pcnl) is a standard, safe, and efficient method for removing large renal calculi. despite development of endourologic equipment, complications of the pcnl are still prevalent. even though therapeutic modalities such as mini-micro pcnl have been developed in recent years, the complications are a serious concern yet. the most important complication is he...

Introduction. Open surgical anatrophic nephrolithotomy (ANL) had been the standard treatment for large renal calculi prior to the development of endoscopic devices and endoscopic techniques. A previous report described the efficacy of ureteroscopy-assisted retrograde nephrostomy (UARN) and presented a case of renal calculi successfully treated with UARN during percutaneous nephrolithotomy (PCNL...

PURPOSE Although the worldwide percutaneous nephrolithotomy (PCNL) practice patterns determined via a survey sent to members of the Endourological Society have been published, differences in PCNL practice patterns among Latin American urologists based on endourological or lithiasis training have not been published. To determine the PCNL practice patterns among Latin American urologists with and...

Four years ago, a 9-year-old boy received percutaneous nephrolithotomy (PCNL) and a 5F DJS was placed thereafter. The DJS was neglected until it caused serious complications including encrustation involving the whole stent, a 5-cm-diameter vesical stone, fragmentation of DJS, and serious urinary tract infection. For this rare and complex case of pediatric lithotomy, we combined PCNL with the su...

The most important step of percutaneous nephrolithotomy (PCNL) is planning the puncture site. A well selected puncture will facilitate nephroscopic navigation and stone clearance. The traditional methods for planning the puncture are intravenous urogram or retrograde pyelogram. Either of these imaging tools is adequate, but new tools such as 3D reconstructed tomography should be more accurate. ...

Since the first successfully performed in 1976 [1], Percutaneous Nephrolithotomy (PCNL) has gradually become the major treatment option for renal stones. Four years later, with the application of Extracorporeal Shock Wave Lithotripsy (ESWL), it is preferred by many urologists and patients as a low morbidity outpatient procedure. However, with the decrease of incidence of large and complex renal...

A 77-year-old female presented with bilateral staghorn calculi. She underwent an uneventful left percutaneous nephrolithotomy (PCNL); the stone analysis revealed a 90% struvite and 10% calcium phosphate stone. Treatment of the right stone was postponed by the patient. During the next 9 months, her family physician gave her multiple courses of culture-directed antibiotics due to breakthrough uri...
