Ureterolithiasis

We evaluated the need for routine ureteral stenting after uncomplicated ureteroscopic lithotripsy (URSL) without dilation for lower ureteral stones larger than 1 cm. A total of 43 patients underwent URSL for lower ureteral stones larger than 10 mm. They were randomized into a stented (21) or an unstented (22) group. URSL was performed by using a semirigid ureteroscope and pneumatic lithotripter without ureteral dilation. Additional forceps application (AFA) was used to remove fragments > or =4 mm. Patients in each group were assessed for stone-free rate, stone size, operative time, AFA, hospitalization time, postoperative pain, irritative voiding symptoms, hematuria, re-hospitalization and stricture formation...

PURPOSE: To report our experience with the laparoscopic approach to managing ileal ureter substitution for extensive ureteral stenosis. PATIENTS AND METHODS: Two patients, one man and one woman, ages 38 and 51 years, respectively, underwent laparoscopic ileal substitution between March 2004 and December 2005 because of extensive ureteral stenosis after stone disease management. A three-port technique was used. The ileal segment was managed extracorporeally through a McBurney incision...

A 63-year-old woman presented with visual disturbance. A fever had been noted for 11 days. Right eye visual acuity was 20/50. Left eye visual acuity was 20/20. Inflammatory cclls wcrc present in the right aqueous and the vitreous humor. Tbc right retina was edematous. The left retina and left ocular humors were normal. Urinalysis showcd many white blood cells. Urine culture showed Candida albicans. KUB revealed many small ureteral calculi bilaterally. A diagnosis of fungal endophthalmitis due to pyeloncphritis caused by ureterolithiasis was rendered...

BACKGROUND: It is important to compare the cost and effectiveness of multidetector computed tomography (MDCT) and intravenous urography (IVU) to determine the most cost-effective alternative for the initial investigation of acute ureterolithiasis. PURPOSE: To analyze the task-specific variable costs combined with the diagnostic effect of MDCT and IVU for patients with acute flank pain, and to determine which is most cost effective. MATERIAL AND METHODS: 119 patients with acute flank pain suggestive of stone disease (ureterolithiasis) were examined by both MDCT and IVU...

Tumours of head and neck present 12.2% of the pernicious tumours' morbidity rate in Poland. Annually, the number of new cases is around 6500. The authors of this work present a case of a 65-year-old farmer who has been smoking for 40 years and occasionally abusing alcohol. The medical history of the patient includes: arterial hypertension, ureterolithiasis, obesity. The patient's brother suffered from knee cancer. In 1998 the patient underwent ablation of carcinoma (2x2 cm) from the left auricle. The result of histopathological examination was Carcinoma planoepitheliale keratodes...

To determine the clinical value of the real-time-ultrasound-guided minimally invasive percutaneous nephrolithotomy (m-PCNL) technique in the supine position, 92 patients suffering from renal or upper ureteral stones were treated by m-PCNL with a nephroscope/ureteroscope in the supine position. The ipsilateral flanks of the patients with different body sizes were elevated with a 1,000 or 3,000-ml water bag. Under cystoscopy, a ureteral catheter was inserted into the kidney. Normal saline was infused into the kidney via the ureteral catheter to dilate the entire urinary system...

OBJECTIVE: To identify 650 patients who underwent CT for renal colic, and review them for age and gender, in Saudi Arabia. METHODS: Scans were performed on a 16 multislice scanner. A total of 650 patients, with the clinical suspicion of ureteric colic were reviewed; 220 females (33.8%) and 430 males (66.2%), with a female to male ratio of 1:2. Exams were carried out from January 2005 to November 2006, at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia...

OBJECTIVE: Our purpose was to prospectively compare the reader compatibility and acceptability of a range of reduced-dose 16-MDCT images with standard-dose 16-MDCT images for the detection of nephroureterolithiasis using a dose reduction simulation technique. SUBJECTS AND METHODS: The study was HIPAA compliant and institutional review board approved. Fifty consecutive patients with suspected nephrolithiasis were recruited to undergo conventional renal stone unenhanced 16-MDCT with at least 160 mA...

A single-board certified urologist with training and experience in anesthesiology was assigned to treat 502 patients (185 with renal stones, 317 with ureteral stones) using the Dornier Compact Delta lithotripter under general or epidural anesthesia. Data were obtained regarding stone location, stone size, shockwave use, stone-free rate, and complications. In all, 502 stones were treated with the Dornier Compact Delta lithotripter. Among renal stones, 73% were in the renal pelvis. Among ureteral stones, 60% were in the upper, 10% in the middle, and 30% in the lower ureter...

A case of gossypiboma (retained surgical sponge) is described which caused ureteroappendiceal fistula 4 years after an open right ureterolithotomy operation. The patient was treated by removal of the retained sponges, appendectomy and ureteral stent insertion.

We report a rare case of ectopic ureter accompanied by a giant ureteral stone and pyonephrosis. A 19-year-old Japanese woman consulted our hospital due to low-grade fever and pain in the left flank. The patient had seeping urinary incontinence since childhood. Ultrasonography demonstrated left dysplastic lumbar kidney with hydronephrosis and plain kidney-ureter-bladder film showed a left giant ureteral stone. The left kidney showed no excretion of contrast medium on drip infusion pyelography. After further examination, a diagnosis of left simple ectopic ureter emptying into the vagina was made...

PURPOSE: We investigated the characteristics and diagnosis of primary asymptomatic ureteral calculi. MATERIALS AND METHODS: During a period of 12 years asymptomatic ureteral stones were prospectively investigated at the Urological Stone Center. We studied mode of diagnosis, stone size, localization, composition, hydronephrosis grade and patient characteristics. RESULTS: Between 1995 and 2006 a total of 40 patients with asymptomatic ureteral stones were identified among 3,711 patients with ureteral stones (1...

AIM: Urinary stone disease is a common condition affecting up to 12% of the population. Speedy elimination of ureterolithiasis in the lower part of ureters is reported with the alpha 1-blocker. This study was carried out to characterize the alpha 1 adrenoceptors (AR) subtype gene and protein expression in the proximal, medial, and distal regions of the human ureter with the aim of facilitating stone expulsion. METHODS: The study was carried out on 20 volunteers...

CONTEXT AND OBJECTIVE: Recent studies have shown noncontrast computed tomography (NCT) to be more effective than ultrasound (US) for imaging acute ureterolithiasis. However, to our knowledge, there are few studies directly comparing these techniques in an emergency teaching hospital setting. The objectives of this study were to compare the diagnostic accuracy of US and NCT performed by senior radiology residents for diagnosing acute ureterolithiasis; and to assess interobserver agreement on tomography interpretations by residents and experienced abdominal radiologists...
