BACKGROUND: Percutaneous nephrolithotomy (PCNL) is recommended for treating staghorn stones or stones measuring > 20 mm. Extracorporeal shockwave lithotripsy (ESWL) or flexible ureteroscopy (URS) may be used as a complement. However, PCNL can cause trauma to the kidney parenchyma, and patients may find a noninvasive procedure, such as ESWL, to be more attractive. OBJECTIVES: The aim of this study was to evaluate the clinical efficiency of MiniJFil® stenting associated with ESWL or second-line URS for the treatment of medium-to-large kidney stones...

Significant literature has an impact on the reader. Reading the novella Heart of Darkness by Joseph Conrad as a young boy rose emotions comparable to those I felt when losing a patient after percutaneous nephrolithotomy (PCNL) as a grown up. The case of a 37-year-old woman with bilateral staghorn and a fatal outcome after PCNL is presented and alternatives are discussed.

The objective of the study is to identify factors predicting development of pyonephrosis in patients of renal calculus disease (RCD), as this knowledge is largely unknown. Patients of RCD without pyonephrosis (Group 1) or with pyonephrosis (Group 2) presenting between December 2013 and November 2015 were evaluated. All patients of RCD who had undergone either percutaneous nephrostomy (PCN) or surgical management (percutaneous nephrolithotomy/pyelolithotomy/nephrectomy) were included. Patients treated conservatively, by extracorporeal shock-wave lithotripsy and patients of bilateral RCD were excluded...

Hemangiopericytomas are soft tissue tumors composed of pericytic cells that are characterized by their "staghorn" vascular branching and their variable clinical presentation. Fifteen to 25% of all HPC occur in the head and neck, with only 5% found in the nose or paranasal sinuses. Sinonasal hemangiopericytoma (SNHPC) is considered distinct from its soft tissue counterpart - the former showing a more uniform cellular organization, has convincing pericytic differentiation and is associated with a far better prognosis...

Background: Percutaneous nephrostolithotomy is an important approach for removing kidney stones. Puncturing and dilatation are two mandatory steps in percutaneous nephrolithotomy (PCNL). Uncommonly, during dilatation, the dilators can cause direct injury to the main renal vein or to their tributaries. Case Presentation: A 75-year-old female underwent PCNL for partial staghorn stone in the left kidney. During puncturing and dilatation, renal vein tributary was injured, and the nephroscope entered the renal vein and inferior vena cava, which was clearly recognized...

Objectives: Percutaneous nephrolithotomy on staghorn calculi is challenging for urologists because it is difficult to remove all of the stones. The purpose of this study was to evaluate the associated factors of stone-free rate after primary percutaneous nephrolithotomy on staghorn calculi in a large series of patients at a single, tertiary referral, endourologic stone center. Methods: We collected data from medical record between January 2000 and December 2015. A total of 345 primary percutaneous nephrolithotomy procedures were performed for patients with staghorn calculi...

To assess the outcomes of percutaneous nephrolithotomy (PCNL) in bilateral staghorn calculi in pediatric patients, we have performed a retrospective analysis. Staghorn calculus is defined as stone that fills a greater part of the pelvic-caliceal system. Still, in developing countries, patients may present with staghorn calculus. PCNL is the preferred treatment modality for staghorn calculus both in adult and children. Our study included fifty-one pediatric patients (<15 years) of bilateral staghorn calculi from 2004 to 2015...

INTRODUCTION: Nephrolithiasis is a complex disease affecting all age groups globally. As the causative factors for nephrolithiasis rises significantly, its incidence, prevalence and recurrence continues to baffle clinicians and patients. AIM: To study the prevalence of different types of renal stones extracted by Percutaneous Nephrolithotomy (PCNL) and open surgical procedures. MATERIALS AND METHODS: Renal stones from 50 patients were retrieved by Percutaneous Nephrolithotomy (PCNL), Ureterorenoscopy (URS) and open surgical techniques for qualitative tests for detection of calcium, oxalate, uric acid, phosphate, ammonium ion, carbonate, cystine and xanthine...

INTRODUCTION: Paraplegic patients are at greater risk of developing complications following ureteroscopic lithotripsy because of urine infection associated with neuropathic bladder, difficulties in access due to altered anatomy of urinary bladder and urethra, spinal curvature, spasticity, and contractures. We report the occurrence of large subcapsular hematoma following ureteroscopy and discuss lessons we learn from this case. CASE REPORT: A 48-year-old male patient with spina bifida underwent ureteroscopy with laser lithotripsy and ureteric stenting for left ureteric stone and staghorn calculus with hydronephrosis; laser lithotripsy was repeated after 3 months; both procedures were performed by a senior urologist and did not result in any complications...

Pleural effusions due to pleural injury following supracostal percutaneous nephrolithotomy (PCNL) occur in upwards of 15% of patients; however, these effusions are invariably diagnosed immediately postoperative or during the hospital stay. Herein, we report our initial experience with a delayed nephropleural fistula. A 52-year-old female underwent an uneventful supracostal right PCNL staghorn stone procedure and was discharged on postoperative day 1. She presented to the emergency department 8 days after her original procedure and one day after ureteral stent removal in the office, with right pleural effusion, concomitant contralateral renal colic secondary to migration of a left pelvic stone into her left proximal ureter, and acute renal failure/oliguria...

BACKGROUND: Staghorn calculi are well-established risk factors for recurrent urinary tract infections (UTIs) and subsequent renal deterioration. Less commonly, long-term urothelial irritation from a calculus may also pose a risk of malignant transformation. CASE PRESENTATION: A 77-year-old male with multiple medical comorbidities presented with a chronic right renal pelvic staghorn calculus and findings concerning for emphysematous pyelonephritis. He was subsequently taken to the operating room for a planned laparoscopic right nephrectomy...

BACKGROUND: Recently endoscopic combined intrarenal surgery (ECIRS) has been introduced as an innovative approach for the treatment of complex single, multiple, and staghorn urolithiasis, which reveals to be a viable alternative to standard percutaneous nephrolithotomy. Although considered to be a versatile, safe, and efficient endoscopic procedure, it is not free from complications. We would like to report two rare cases of hydroperitoneum that occurred during ECIRS and their management...

Myopericytoma are uncommon, slow-growing benign perivascular neoplasms that show hemangiopericytoma-like vascular pattern. We report a 52-year-male patient with a painless palpable nodule in the left thumb for the past 9 months. The mass, on the thenar aspect, was 15x12mm in size. X-ray revealed a soft tissue swelling with no bony association. The excised nodule was a non-capsulated, well-circumscribed vascular neoplasm composed of proliferating spindle to ovoid bland cells with eosinophilic cytoplasm. A concentric perivascular arrangement of the cells was seen interspersed by thin-walled, branching, staghorn blood vessels...

PURPOSE: Scoring systems have been devised to predict outcomes of percutaneous nephrolithotomy (PCNL). CROES nephrolithometry nomogram (CNN) is the latest tool devised to predict stone-free rate (SFR). We aim to compare predictive accuracy of CNN against Guy stone score (GSS) for SFR and postoperative outcomes. MATERIALS AND METHODS: Between January 2013 and December 2015, 313 patients undergoing PCNL were analyzed for predictive accuracy of GSS, CNN, and stone burden (SB) for SFR, complications, operation time (OT), and length of hospitalization (LOH)...
