RESUMO
PURPOSE: The present study was designed to evaluate the incidence and characteristics of acquired cystic kidney disease (ACKD) in patients with end-stage renal disease who were treated by chronic hemodialysis, using renal ultrasonography. MATERIALS AND METHODS: We performed renal ultrasonography as a screening modality in 112 patients treated with long-term hemodialysis due to end-stage renal disease. We classified the patients years from one to six years. RESULTS: In our study, cystic lesions were noted in 41 patients (36.6%) and there was no sexual predilection of ACKD. Also, a prolonged period of hemodialysis increased the incidence of ACKD, especially for those treated more than 49 months. We encountered a case of renal cell cancer, evaluated it with CT, and then treated it by radical nephrectomy. CONCLUSIONS: With these results, renal ultrasonography can be used as a screening modality in patients treated with long-term hemodialysis more than 49 months due to end-stage renal disease. As complications occur, further evaluation will be needed.

Xanthogranulomatous pyelonephritis is an uncommon form of chronic pyelonephritis occurring usually in middle-aged women. This disease is characterized by destruction of the renal parenchyma which is then replaced by granulomatous tissue containing lipid-laden macrophages (foam cells). But this disease is hard to diagnose preoperatively since it resembles renal abscess, renal cell carcinoma, renal tuberculosis and so forth. Xanthogranulomatous pyelonephritis in children is rare. We report a case in a 30 month-old boy.

The Urachus lies between the peritoneum and transversalis fascia and extends from the anterior dome of the bladder toward the umbilicus. During the 4th and 5th months of gestation, the urachus narrows to a small-calibered epitherial tube. During fetal development, as the bladder descends into the pelvis, its apical portion narrows progressively into a fibromuscular strand of urachus. Recently, we reviewed three cases of urachal anomalies with literatures.
