urinary lithiasis

A Serrano, J Salinas, S López de Alda, F Parra, M Sánchez, M A Ruiz León, J Moreno
Double J stents are used in Urology in an important number of pathologies. These devices contribute to solve very prevalent pathologies such as upper urinary tract lithiasis. However, there are very frequent symptoms associated with double J catheters that may produce a very important constraint on the quality of life of patients. Although theses symptoms are not severe in most cases, they require medical treatment to be solved in certain patients. Several types of drugs such as analgesics, anti-inflammatories, antibiotics, anticholinergics and alpha-blockers have been used for this pathology, with variable results depending on the authors...

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others...

Fifty-four patients with infected renal lithiasis underwent complete metabolic evaluation searching for underlying factors contributing to stone formation including urine analysis and culture. Metabolic abnormalities were significantly more present in patients with mixed infected stones (struvite+/-apatite and calcium oxalate) than in patients with pure infected stones (struvite+/-carbonate apatite): hypercalciuria in 40%, hyperoxaluria in 34% and hyperuricosuria in 28% (p < 0.05). Urinary excretion of citrate was low in both groups without statistically significant difference (238+/-117 mg/24 h vs 214+/-104 mg/24/h, t = 0...

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...

A 74-year-old man presented with right flank pain and a palpable mass in the left flank. Blood pressure was normal. Contrastenhanced computed tomography (CT) showed a 17 × 16 × 12 cm retroperitoneal mass over the left kidney, solid and heterogeneous. There were also 3 retro aortic lymph nodes and bilateral renal lithiasis. Twenty four-hour urinary metanephrines and normetanephrines were normal. The patient underwent a resection of the mass with left adrenalectomy by a lumbar incision. Histological findings revealed an adrenal oncocytic neoplasm (AON) with uncertain malignant potential...

Encrusted uretero-pyelitis is a rare and serious disease, related to the presence of calcifications in the pelvicalyceal system and ureter, associated with chronic urinary tract infection. In most cases, the causal agent of this infection lithiasis is corynebacterium urealyticum. The specific aspect of calcifications on CT scan can help to suggest diagnosis. To avoid a delay in diagnosis (which is frequent), an accurate exploration by the bacteriologist is crucial. The combination of a glycopeptides antibiotherapy and urine acidification has proved its effectiveness, as described in the medical literature...

PURPOSE: To evaluate the role of multidetector computed tomography (MDCT) in recognizing the complications of extracorporeal shock wave lithotripsy (ESWL) and providing a prognostic grading system for the therapeutic approach. MATERIALS AND METHODS: A total of 43 patients who underwent ESWL because of urinary stone disease were assessed by 320-row MDCT examination before and after ESWL. Pre-ESWL CT unenhanced scans were performed for diagnosing stone disease. Post-ESWL CT scans were acquired before and after intravenous injection of contrast medium searching for peri-renal fluid collection or hyper-density, pyelic or ureteral wall thickening, blood clots in the urinary tract, peri- or intra-renal hematoma or abscess, active bleeding...

WHAT IS KNOWN AND OBJECTIVE: There are no clinical reports that have compared topiroxostat, a selective xanthine oxidase inhibitor, with allopurinol in serum urate-lowering efficacy. The aim of this study was to compare the efficacy and safety of topiroxostat and allopurinol in Japanese hyperuricemic patients with or without gout. METHODS: A phase 3, multicentre, randomized, double-blind, double-dummy, active-controlled, parallel-group study conducted in Japan. Patients who had inadequate serum urate levels (a gout patient: serum urate level ≥416·4 μmol/L; an asymptomatic hyperuricemic patient with specific complications (urinary lithiasis, hypertension, hyperlipidemia and/or diabetes): serum urate level ≥475·8 μmol/L; and an asymptomatic hyperuricemic patient with no specific complications: serum urate level ≥535·3 μmol/L) were randomized to topiroxostat 120 mg/day or allopurinol 200 mg/day, with an equal allocation ratio, for 16 weeks...

A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used...
