Results: In a cohort of 88 patients (57 male and, 31 female) PCNL was performed for renal stone treatment. The mean age was 33.5 (9 – 65) years. The mean operative time was 85 (60 – 180) minutes and the mean stone size was 3.2 cm range (2.5-4.8) cm. There were 37 staghorn and 51 non staghorn stone. PCNL via a single access tract was accomplished in 86% (76/88) of procedures, with upper pole cal...

PURPOSE Tubeless percutaneous nephrolithotomy (PNL) remains a challenging technique for the surgical treatment of staghorn renal calculi. Our study was designed to compare surgical outcomes between conventional and tubeless PNL. MATERIALS AND METHODS We retrospectively enrolled consecutive patients who underwent conventional or tubeless PNL under general anesthesia performed by a single surge...

Introduction: Urolithiasis is rare in developed countries. Staghorn calculi are a type of upper urinary tract stone that involves the renal pelvis and extends into at least two calyces. Although all types of urinary stones can potentially form staghorn calculi, approximately 75% are composed of a struvite matrix and are generally associated with urinary tract infection caused by urea -splitting...

results in group 1, the mean largest and cumulative stone diameters, respectively, were 18.7 ± 5.7 mm and 45.0 ± 12.0 mm. in group 2, the mean volume was 6,288.4 ± 2,733.0 mm3. the overall sf was 96.4% (100% for group 1 and 75% for group 2). the mean number of sessions of eswl and urs, respectively, was 1.4 ± 0.7 and 0.8 ± 0.9 in group 1 and 4.0 ± 2.0 and 1.5 ± 1.3 in group 2. the mean times to...

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...

BACKGROUND Kidney stones in patients with autosomal dominant polycystic kidney disease are common, regarded as the consequence of the combination of anatomic abnormality and metabolic risk factors. However, complete staghorn calculus is rare in polycystic kidney disease and predicts a gloomy prognosis of kidney. For general population, recent data showed metabolic factors were the dominant caus...

OBJECTIVES To assess the feasibility of performing percutaneous nephrolithotomy (PCNL) with the patient supine. Although PCNL with the patient prone is the standard technique for treating large (>2 cm) renal stones including staghorn stones, we evaluated the safety and efficacy of supine PCNL for managing large renal stones, with special attention to evaluating the complications. PATIENTS AND...

OBJECTIVES To review reports focusing on the surgical treatment of staghorn stones in children, as despite all the improvements in the surgical treatment of paediatric urolithiasis the management of staghorn calculi still represents a challenging problem in urology practice. METHODS To evaluate current knowledge about treating staghorn calculi in children, we searched PubMed for relevant arti...

Objective: To access the safety and efficacy of tubeless percutaneous nephrolithotomy (PCNL). Materials and methods: Since January 2001, 1000 consecutive tubeless PCNLs performed at our hospital were enrolled into this retrospective chart review. The average age of the patients (659 males and 341 females) was 54.4 ± 12.6 years, and 55 patients were 75 years old or older. The stone characteristi...

OBJECTIVE To present the results of percutaneous nephrolithotomy (PCNL) for treating staghorn stones. PATIENTS AND METHODS A database was compiled from the computerised files of patients who underwent PCNL for staghorn stones between 1999 and 2009. The study included 238 patients (128 males and 110 females) with a mean (SD) age of 48.9 (14) years, who underwent 242 PCNLs, and included staghor...
