RESUMO
Bowel intussusception is rare in adults and is usually driven by an underlying pathological process affecting the bowel. Renal cell carcinoma (RCC) is the most common type of kidney cancer and its disease course, depending on the initial histology and disease stage, can metastasize to adrenal glands, lungs, bones, brains and contralateral kidney that can be challenging to follow. We present the case of a patient with a history of radical left nephrectomy for RCC that developed an acute bowel obstruction, secondary to an ileal metastasis of RCC. In previous surgeries, small bowel obstruction (SBO) is usually found due to adhesions, nonetheless in a patient with a history of high-grade disease at diagnosis, one must keep in mind the possibility of disease relapse in the setting of SBO.
RESUMO
Placement of a percutaneous nephrostomy (PCN), to drain and preserve renal function, is a common urologic procedure in the setting of high urinary obstruction. Colonic perforation is a rare complication, with an incidence of 0.2-0.5%. In these situations, literature advises the withdrawal of the PCN into the colon, ureteral stenting, zero-diet, broad spectrum antibiotics and only to remove the catheter days after. Here we describe the case of a patient in whom a PCN was placed transversing the colon, in whom it was retrieved under endoscopic control, with use of endoclips to control the hemorrhage and close the perforation.
