Horseshoe kidney is the most common of all renal fusion anomalies, occurring in approximately 0.25% of the general population. Horseshoe kidney with only a single ureter is a rare anomaly. A 60-year-old man was admitted to hospital for routine health screening. His family history was negative for kidney diseases, and there was no abnormality in his physical examination. A computed tomography (CT) scan revealed an atypical horseshoe kidney with cysts and three-dimensional spiral CT reconstruction showed the presence of a single ureter. The patient has since been followed up for two years without any signs of clinical disease. We report a rare case of a patient with a horseshoe kidney with cysts and a single ureter that was diagnosed incidentally.

From 1978 to 1987, 139 children were treated for osteomyelitis at our institution, among them 6 with osteomyelitis of the clavicle. All six patients presented with a primary chronic osteomyelitis. Three children sustained a trauma anamnestically. Pathohistological examinations revealed a chronic, unspecific inflammation in all cases. Immobilisation was achieved by means of a DESAULT-cast or an abduction splint for 7 to 36 weeks, antibiotics (clindamycin) were given for 6 to 55 weeks, starting with intravenous administration for 1 weeks maximally. All patients were primarily operated on, mostly undergoing curettage of affected regions or partial resection. After 4 to 10 years, 4 children are well and without evidence of recurrence, 2 children are still under treatment for recurrences.

ResumoFístula arteriovenosa (FAV) é uma rara complicação pós-nefrolitotripsia percutâ-nea (NLP). Apresentamos o caso de um paciente de 70 anos, sexo masculino, que apresentou sangramento maciço após NLP, tratado por angioembolização renal superseletiva com implante de stent. Após a embolização, houve resolução do sangramento. FAV é uma complicação incomum da NLP, que pode ser tratada com sucesso com angioembolização.Palavras-chave: fístula arteriovenosa, nefrolitotomia percutânea, nefrolitotripsia percutânea. AbstRActArteriovenous fistula (AVF) is a rare complication of percutaneous nephrolithotomy (PNL). We report the case of a 70-year-old man, who had massive bleeding after PNL and underwent treatment with superselective renal angiographic embolization and stent implantation. Bleeding resolved after embolization. Arteriovenous fistula is an uncommon complication of PNL, which may be successfully treated with angiographic embolization.
