BACKGROUND: The aim of this study was to evaluate the role of flexible cystoscopy in preventing malpositioning of the ureteral stent after laparoscopic ureterolithotomy in male patients. METHODS: From April 2009 to June 2015, 97 male patients with stones >1.8 cm in the upper ureter underwent intracorporeal double-J stenting of the ureter after laparoscopic ureterolithotomy performed by four different surgeons. In the last 50 patients who underwent laparoscopic ureterolithotomy flexible cystoscopy was performed through the urethral route to confirm the position of the double-J stent, while in the first 47 correct positioning of the stent was confirmed through postoperative KUB...

A duplex ureter constitutes about 1% of the renal tract anomalies.A 39-year-old man presented with a 4-week history of left loin pain and microscopic haematuria. Investigation with a non-contrast CT KUB revealed a 6 mm non-obstructing calculus in the left distal ureter.Left ureteroscopy and lithotripsy was planned. However, ureteroscopy failed to identify the calculus. A double J ureteric stent was left in situ and the procedure abandoned in favour of further assessment with a CT urogram. Imaging surprisingly showed a left duplex ureter with the calculus in the non-stented ureter...

BACKGROUND: Almost all endourologic procedures use fluoroscopic imaging in some steps, which exposes both the patient and the surgical team to considerable amounts of radiation. Primary reports on results of a simple direct visual endoscopic access sheath placement technique which does not use fluoroscopy at all are presented. MATERIAL AND METHODS: First a semi-rigid ureteroscopy was carried out up to the renal pelvis, then the access sheath (36 cm, 11/13 Fr) without the obturator was placed over a 7...

OBJECTIVES: To investigate the relationship between the upper urinary stone distribution and the "crossing point"; an area of relative fixation within the upper ureter at approximately the level where the ureter crosses the gonadal vein. METHODS: We reviewed 298 consecutive patients presenting with acute renal colic, identified upper ureteral stones in computed tomography. For stones located at "renal pelvis and upper ureter", we measured the vertebral level of each renal pelvis, crossing point, and stone...

Bladder stones are caused when minerals are built up in the bladder, especially if the bladder is incompletely emptied. These stones will pass while they are small. Otherwise, they get stuck to the bladder wall or ureter. If this happens, they gradually gather more mineral crystals, becoming larger over time. Primary hyperparathyroidism is usually caused by a tumor within the parathyroid gland, and elevated calcium levels can cause digestive symptoms, psychiatric abnormalities, bone disease and multiple kidney stones...

INTRODUCTION: Use of a ureteral access sheath (UAS) within flexible ureteroscopy (fURS) for the management of kidney and ureteral stones has shown improvements in its effectiveness, but it is also associated with increased risk of ureteral injury. Use of ureteral stent (US) after fURS is recommended by some authors, because of its role in reducing postoperative pain and preventing complications. Our objective is to determine if postoperative stenting is necessary in pre-stented patients that underwent fURS using UAS...

A 41-year-old male presented at Emergency Department (ED) with right flank pain associated with hematuria for 3 days. Patient had a previous history of nephrolithiasis. The physical examination and blood tests were normal. Urine analyses showed haematuria > 1.000.000/μL. After clinical evaluation, a computer tomography (CT) showed right ureteral dilata¬tion caused by a 5 mm proximal stone and a distal intraluminal mass of 8 cm in length. In this setting, an ureteroscopic biopsy was performed and revealed a large polypoid lesion histologically suggestive of fibroepithelial polyp...

INTRODUCTION: The treatment of large renal stones (≥1 cm) in paediatric patients is challenging. The usual treatment options include percutaneous nephrolithotomy (PCNL) or shockwave lithotripsy (SWL). There is a rise in the use of ureteroscopy and laser stone fragmentation (URSL) for paediatric stones; however, outcomes of treatment for large renal stones in this age group are still largely unknown. OBJECTIVE: To investigate the outcome of URSL for large paediatric renal stones ≥1 cm treated at the present institution over the last 5 years...
