Aneurisma calcificado de la arteria renal en paciente monorrena, una patología inusual / Renal artery calcified aneurysm in a solytary kidney woman patient, rare pathology

Los aneurismas de la arteria renal son infrecuentes. La prevalencia real de los mismos en la población general es desconocida, aunque se estima que es inferior al 0,4%. Con el uso cada vez mayor de la Angiografía y la Tomografía Computerizada (TC), así como por la mejora en las técnicas de imagen, cada vez se diagnostican con más frecuencia. Las causas más comunes son la displasia fibromuscular y la oclusión arteriosclerótica de la arteria renal. Generalmente no hay una clínica patognomónica de los aneurismas renales, produciendo síntomas inespecíficos como dolor en el costado, hematuria, hipertensión e hipotensión (sospecha de rotura). Presentamos el caso de una paciente monorrena con aneurisma calcificado en la arteria renal

Renal artery aneurysm are uncommon. The true prevalence of renal aneurysms in the general population is unknown (less than 0.4%). Because of more widespread use of Angiography and CT as well as improved imaging techniques, they are diagnosed more frecuently. Fibromuscular dysplasia and arteriosclerotic occlusion of the renal artery are believed to be the most frecuent causes. In general, there are no pathognomonic signs and symptoms of renal aneurysm. Nonspecific complaints include flank pain, hematuria, hypertension and hypotension (suspect rupture of aneurysm). We report a case of a woman with a renal artery calcified aneurysm in a solitary kidney

OBJECTIVE: Indinavir is a protease inhibitor used in the treatment of HIV with a lithogenic capacity as a urological side effect. The pathogenesis, diagnosis and treatment of indinavir urolithiasis are briefly reviewed. METHODS: A 37-year-old male, seropositive for HIV on treatment with indinavir, lamiduvine and zidovudine, consulted for colicky left lumbar pain, nausea, vomiting and dark urine for the past three days. RESULTS: Patient evaluation showed a nonfunctioning left kidney and ureterohydronephrosis of unknown origin. URS showed a yellowish, friable material with a mucinous appearance that occupied the entire lumen of the ureter. Fragmentation was achieved with the lithotriptor probe. Six months later the patient had fully recovered and was asymptomatic. CONCLUSIONS: The incidence of protease inhibitor-induced urolithiasis is increasing. This condition should be distinguished from uric acid calculi whose treatment will aggravate the indinavir urolithiasis.
