Solitary fibrous tumors are well described in the pleura, but rare extra-pleural neoplasms have been reported. We describe a patient with a solitary left renal fibrous tumor who after undergoing a nephrectomy, presented 8 years later with a contralateral metachronous solitary fibrous tumor. Malignant metastatic extra-pleural solitary fibrous tumors are extremely rare, and to our knowledge, this is the first case of contralateral recurrence of solitary renal fibrous tumor. The patient underwent a robotic assisted partial nephrectomy of the right renal mass. Both tumors showed overlapping histopathology.

Ureteral obstruction secondary to an inguinal hernia with transplant ureteral component is an extremely rare entity with only several case reports found in literature. In all previously reported cases, management of the obstruction involved temporary drainage with ureteral stenting or nephrostomy tube placements followed by delayed definitive repair. We present two case reports, here one being the first one managed by immediate definitive repair via ureteral reimplant and herniorrhaphy and a second case by delayed definitive repair after percutaneous nephrostomy tube placement. Both patients continued to do well postoperatively with normalization of renal function on follow-up.
