BACKGROUND: Shock Wave Lithotripsy (SWL) for distal ureteral stones can be performed in prone or supine position. Our aim is to demonstrate the advantage of the supine transgluteal SWL approach for distal ureteral stones treatment using a real times ultrasound (US) focusing and to show how the Computerized Tomography (CT) scan parameters may be related to the outcomes. METHODS: We performed 70 consecutive supine transgluteal SWL of distal ureteral stones. All patients had a pre-treatment CT scan...

A bifid ureter with a distal blind-ending branch is a rare congenital anomaly. Most patients are asymptomatic; only patients with complications, such as infection, vesicoureteral reflux, or stone formation, present symptoms. We describe the case of a patient with urinary stone located in the distal blind-ending branch of a bifid ureter diagnosed during transurethral lithotripsy. Preoperative noncontrast-enhanced computed tomography did not reveal a stone in the distal blind-ending branch of the bifid ureter, but a rigid ureteroscope did; however, it could not reach the stone...

INTRODUCTION: Non-contrast CT (NCT) is commonly used to evaluate flank pain (FP). We sought to evaluate incidence of ureteral calculi on NCT in patients with FP, and to determine if clinical variables are associated with higher detection rates. MATERIALS AND METHODS: Retrospective review identified 613 patients undergoing NCT for FP. Patient clinical data, NCT findings, and intervention were analyzed. Focus was placed on variables commonly associated with urolithiasis (Vstone), comprising hematuria, nausea/vomiting, and prior stone history...

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...

A 34 year-old woman was admitted to our hospital with left flank pain. A non-contrast enhanced computerized tomography (NCCT) revealed a 1.5x2cm left proximal ureter stone. Patient was scheduled for ureterorenoscopy (URS) and stone removal. She was submitted to retrograde intrarenal surgery (RIRS). At the postoperative 1st day, the patient began to suffer from left flank pain. A NCCT was taken, which revealed a subcapsular hematoma and perirenal fluid. The patient was managed conservatively with intravenous fluid, antibiotic and non-steroidal anti-inflammatory drug therapy and was discharged at the postoperative 6th day...

We evaluated the clinical value of flexible ureteroscopic lithotripsy for the treatment of upper urinary tract calculi in infants. Fifty-five infants with upper urinary tract calculi were included in this study: 41 males and 14 females. Retrograde intrarenal surgery was performed by an 8 Fr/30 cm flexible ureterorenoscope (POLY®) combined with a holmium laser. CT scanning or radiography of the kidneys, ureters, and bladder region was performed one month after the operation to confirm the clearance of calculi...

INTRODUCTION: The traditional procedure for the management of bilateral ureteric stones is staged ureteroscopic lithotripsy(URSL). However, in recent years particularly, some urologists advocate same-session bilateral URSL on the ground of success rates and minimal morbidity. This systematic review is to evaluate the efficacy and safety of same-session bilateral ureteroscopy for the treatment of ureteral calculi. MATERIAL AND METHODS: We conducted a bibliographic search using MEDLINE(1980 to August 2015), EMBASE(1980 to August 2015)...

BACKGROUND: Endourology is a widely used means by which to manage urolithiasis. Patient anatomy can oftentimes limit what can be accomplished with current technology. CASE PRESENTATION: This is a case of a patient with renal and ureteral stones within a transplant kidney. Her anatomy would not allow for a standard retrograde ureteroscopic approach. We describe a method by which to overcome this difficult scenario by using a rigid cystoscope as a platform by which a ureteroscope was passed to allow for stone removal...

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: Urinary stones disease is becoming more common not only in adults but also in children. Most cases are resolved with extracorporeal shock wave lithotripsy, but miniaturization of endoscopes has increased the use of ureteroscopy in resolving ureteral stones, most notably in children. CASE PRESENTATION: This presentation focuses on two cases of microureteroscopy. In both cases, the presence of lithiasis in the pelvic ureter was suspected to be the cause of ureter hydronephrosis, and a microureteroscopy was performed for treatment purposes...

Patients with severe skeletal deformities are a challenging group to treat. A female, white, 35-year-old presented with right kidney stones located in renal pelvis, lower calyx, and upper ureter. She was affected by severe spinal deformity with restrictive respiratory obstruction, caused by kyphoscoliosis. Percutaneous nephrolithotomy in supine position was performed, achieving complete removal of kidney stones. The treatment of renal stones in this patient was complex, so special attention to respiratory function was mandatory; this was a challenging but feasible situation...

Kidney stone imaging is an important diagnostic tool and initial step in deciding which therapeutic options to use for the management of kidney stones. Guidelines provided by the American College of Radiology, American Urological Association, and European Association of Urology differ regarding the optimal initial imaging modality to use to evaluate patients with suspected obstructive nephrolithiasis. Noncontrast CT of the abdomen and pelvis consistently provides the most accurate diagnosis but also exposes patients to ionizing radiation...

Double-J (DJ) stents are the main tools used in urological practice for prevention and treatment of obstruction. Stenting is also mandatory after complicated ureteroscopy or TUL (Transureteral Lithotripsy). Known complications are upper migration of DJ stents into the kidney and lower migration to the bladder. In a man with an impacted right lower ureteral stone, a DJ stent was placed because the ureteroscope was not passed from an intramural ureter. We reported a very rare complication of DJ ureteral stent placement with intravascular migration to the pulmonary arteries, which was removed percutaneously through the right femoral vein under fluoroscopic guidance...
