[Obstructive anuria secondary to left external iliac artery aneurysm. Case report].

OBJECTIVE: To report one case of obstructive anuria due to ureteral compression by an external iliac artery aneurysm in a patient with a single kidney. METHODS/RESULTS: We report the case of a 76-year-old male with a single kidney presenting at the emergency department with left lumbar pain and anuria for several days. Hydronephrosis of the solitary left kidney due to an aneurysmatic tumor of the external iliac artery was diagnosed after performing various tests (ultrasound, arteriography). Emergency percutaneous nephrostomy was performed with subsequent vascular repair of the aneurysm. The outcome was favourable. CONCLUSIONS: Aorto-iliac aneurysm constitutes a rare cause of obstructive anuria. Patients affected are usually males over 50 years of age, smokers, with a history of diabetes mellitus, arterial hypertension (AHT), chronic obstructive pulmonary disease (COPD), etc. Diagnosis is based on clinical symptoms, outstandingly lumboabdominal pain, and the finding of a beating abdominal tumor, as well as signs of a renal failure. Useful complementary studies for diagnosis include ultrasound, intravenous urography (IVU), arteriography and computerised axial tomography (CT). Surgical treatment of the aneurysm generally relieves the obstruction.

[Complete triple ureter. Case report].

OBJECTIVE: To report the case of a left complete triple ureter with ureteral pyelocalicial system draining independently into the bladder in a patient consulting for episodes of right renal colic. METHODS/RESULTS: 27-year-old female patient consulting for episodes of right renal colic. Several studies including intravenous urography and CT scan were performed revealing a right renal lithiasis and a double ureteral pyelocalicial system on the right side; the left kidney showed three pyelocalicial systems with three ureters, draining each of them separately into the bladder. CONCLUSIONS: The anomalies of ureter number are generally diagnosed by signs and symptoms of obstruction, infection, lithiasis, hematuria, pain, reflux, and ureterocele. Cases of triple ureter are generally are accompanied by other ureteral number anomalies of the opposite kidney. Intravenous urography is an effective diagnostic tool, although CT scan ultrasound may also help to clarify the diagnosis.

[Calcified uterine myoma. Presentation of 3 cases].

OBJECTIVES: To report three cases of uterine myoma as cause of pelvic calcification and to establish differential diagnosis with bladder stones. METHODS/RESULTS: Three asymptomatic female patients, ages between 54 years (one patient) and more than 70 years (two patients), were fortuitously found to have calcified uterine myomas by radiological studies made for suspicion of other pathologies. CONCLUSIONS: Discovering of calcified uterine myomas is not frequent. Diagnosis is made by radiological studies in postmenopausal female patients. The significance from the urological point of view is to do differential diagnosis with bladder stones.

[Lithiasis of soft appearance within a calyceal diverticulum in the right kidney. Report of one case and therapeutic management].

OBJECTIVES: To report the case of a 28-year-old female patient carrying a lithiasis of soft appearance located within a calyceal diverticulum in the right kidney which presented clinically during pregnancy, and to comment on therapeutic management, as well as the outcome one year after conservative treatment. METHODS AND RESULTS: 28-year-old female patient with history of renal colic during pregnancy, who presents at our clinics in the postpartum period with a recurrent abdominal and lumbar pain. Kidney-ureter-bladder (KUB) x-ray and intravenous urography (IVP) detected a lithiasis of soft appearance within a calyceal diverticulum in the right kidney. Treatment was conservative with potassium citrate/citric acid and follow-up controls with urine culture (every 3 months) and ultrasounds (every 8 months). Currently she is asymptomatic but the lithiasis persists on KUB and urine culture is positive (Escherichia coli) and receives treatment with cefuroxime 250 mg every 12 hours for 6 days and nitrofurantoin 100 mg every night for three months. CONCLUSIONS: Most urinary stones located within calyceal diverticula have an asymptomatic course, treatment not being necessary. The most frequent clinical presentations of these stones are flank pain, urinary infection demonstrated by positive urine culture, and incidental finding. IVU is an effective method for diagnosis. ESWL is not an effective treatment for them, being percutaneous techniques the most suitable for a single-surgical procedure resolution of both lithiasis and pyelocalyceal diverticulum.
