Three patients were reinspected by ureteroscopy after repeat ESWL. Ureteroscopy initially did not disclose an intraluminal stone and only visualized a severe inflammatory reaction of the ureteric wall and a boss of the ureter at the level of the fluoroscopically suspected stone location. An intact stone in all 3 cases was finally exposed by tactile contact at the top of the ureteroscope after p...

BACKGROUND In recent years, bladder stones are increasing in China. However, a giant bladder stone is rarely found nowadays. METHODS A case of a 54-year-old man who presented with a >9-year history of urinary frequency and urgency and macrohematuria for the past 3 days, was examined by ultrasound scan, kidney-ureter-bladder x-ray, and computed tomography. Then, the patient received a cystolit...

In order to promote stone passage in renal colic, we must first understand normal ureteral activity and how this is affected by the presence of a stone. Measuring normal ureteral activity in humans is difficult without the use of invasive methods or techniques which in themselves may affect peristalsis. Monitoring the activity during confirmed renal colic is even more difficult and virtually im...

We present a case of complete renal duplex with H-shaped double ureter opening into the bladder with 2 separate orifices. It is an extremely rare variety of renal duplex which was reported only once in the literature. Fifty-four-year-old male presented to our department with right renal pain. Noncontrast CT revealed stone midthird right ureter with duplex right kidney. Retrograde ureteropyelogr...

PURPOSE To evaluate the effects of a reverse thermosensitive polymer during ureteroscopy with laser lithotripsy in an in vivo porcine model. MATERIALS AND METHODS Six pigs underwent general anesthesia followed by bilateral ureteroscopy with laser lithotripsy of stone phantoms while measuring intrapelvic renal pressures through bilateral nephrostomy tubes. The procedures were performed in one ...

The effect of combining therapy with hydrochlorothiazide, allopurinol and systemic alkalization for urolithiasis with lower urinary pH was examined. A total of 90 patients were followed up for 1 to 3 years, the average follow up period being 18 months. The total stone disappearance rate was 60% (kidney stone), 74% (ureter stone) and 20% (bladder stone). Large amounts of thiazide diuretics, pota...

ABSTRACT Background: Holmium YAG (yttrium-aluminum-garnet) laser, a comparatively new technique, can clear all types and sizes of stones is only being used in two institutes Karachi, Pakistan. The study aimed to compare pneumatic lithoclast holmium evaluate stone-free rate (SFR), postoperative complications, operative duration, effectiveness. Methods: This cross-sectional research included 60 p...

BACKGROUND Pakistan lies in the Afro-Asia stone belt. Ureteric calculi are common occurrence and a major burden on health care facilities in Pakistan. The objective of this study was to assess the efficacy and safety of pneumatic lithoclast in the management of ureteric calculi. METHODS Case series study Department of Urology at Institute of Kidney Diseases Hayatabad Peshawar, from 1st Oct 20...

The conventional use of a basket involves a metallic wire section that is contained within a polythene sheath. The wire basket can be withdrawn or protruded from the sheath using a handle. The advantage of this system is that the basket can be kept shut or open at will within the ureter. Thus one can keep the basket closed in order to maneuver the basket past a stone before opening it above the...
