Abstract

Renal cryotherapy has been described as a minimally invasive procedure that represents an alternative for selected patients with small renal tumors. Our preliminary experience with this procedure is reported. [corrected] Eighteen patients with 21 tumors with a mean tumor size of 2.2 cm (1-4) in the preoperative CT scan underwent renal cryotherapy using a double freeze-thaw cycle. The group consisted of 14 males (64%) and 4 females (18% with a mean age of 68 years (32-84). All patients had undergone prior surgery for renal tumor in the treated or the opposite kidney. A transperitoneal laparoscopic approach was used in all patients. Mean operating time was 196 minutes (120-140), and no patient received transfusions during or after surgery. No complications occurred in 14 patients (64%). Perirenal abscess, splenic laceration, ureteral lesion, and polar artery lesion occurred in one patient each. Peroperative biopsy was performed in 5 patients (22.7%) and was positive for renal cancer in two cases, while material was insufficient in three patients. Mean hospital stay was 6 days (2-16). Creatinine levels were 106 mg% (48-230) before surgery and 123 mg/% (52-270) 6 months after surgery. A CT scan was performed in all patients one and...Continue Reading
