Bilateral Laparoscopic Partial Nephrectomies: A Case Report

Although laparoscopy is a recognized operative approach to the management of renal masses, there is currently no standardized approach to manage bilateral synchronous renal masses. We present a case of synchronous bilateral renal masses, identified during work-up for flank pain, and managed simultaneously with laparoscopic partial nephrectomies. The patient is a 42-year-old Caucasian male found to have bilateral renal masses during evaluation for left flank pain. Cross-sectional imaging studies showed a 7.0???7.3???5.2?cm anterior, mid-to-lower pole mass on the left kidney and a 1.5???1.9???1.6?cm medial lower pole mass on the right kidney. He underwent bilateral laparoscopic partial nephrectomy at the same setting, with an uncomplicated postoperative course. Pathology report revealed clear cell renal-cell carcinoma (ccRCC) on both sides. He had normal renal function and no evidence of recurrence in the first 6 months of follow-up. This case demonstrates the possibility and safety of performing bilateral laparoscopic partial nephrectomies in one operative session. Our review of the literature supports the role of genetic counseling and the need for long-term surveillance in young patients having RCC.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/140344/1/cren.2015.0007.pd

Clinical, Pathologic, and Functional Outcomes After Nephron-Sparing Surgery in Patients with a Solitary Kidney: A Multicenter Experience

Abstract Background and Purpose: Surgical management of a renal neoplasm in a solitary kidney is a balance between oncologic control and preservation of renal function. We analyzed patients with a renal mass in a solitary kidney undergoing nephron-sparing procedures to determine perioperative, oncologic, and renal functional outcomes. Patients and Methods: A multicenter study was performed from 12 institutions. All patients with a functional or anatomic solitary kidney who underwent nephron-sparing surgery for one or more renal masses were included. Tumor size, complications, and recurrence rates were recorded. Renal function was assessed with serum creatinine level and estimated glomerular filtration rate. Results: Ninety-eight patients underwent 105 ablations, and 100 patients underwent partial nephrectomy (PN). Preoperative estimated glomerular filtration rate (eGFR) was similar between the groups. Tumors managed with PN were significantly larger than those managed with ablation (P<0.001). Ablations were associated with a lower overall complication rate (9.5% vs 24%, P=0.01) and higher local recurrence rate (6.7% vs 3%, P=0.04). Eighty-four patients had a preoperative eGFR ≥60?mL/min/1.73?m2. Among these patients, 19 (23%) fell below this threshold after 3 months and 15 (18%) at 12 months. Postoperatively, there was no significant difference in eGFR between the groups. Conclusions: Extirpation and ablation are both reasonable options for treatment. Ablation is more minimally invasive, albeit with higher recurrence rates compared with PN. Postoperative renal function is similar in both groups and is not affected by surgical approach.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98449/1/end%2E2012%2E0114.pd

Past, present, and future of laparoscopic renal surgery

Although laparoscopic renal surgery dates to almost 30 years ago, in which the first laparoscopic nephrectomy was performed in 1990, the history of laparoscopy extends back over 100 years, when laparoscopy was first performed on dogs. Over the last 30 years, laparoscopic renal surgery has seen many advancements in technology and technique. With the introduction of robotics and new instruments, renal surgery is becoming increasingly less invasive, and patients are having improved operative outcomes. As new technology develops, the envelope will continue to be pushed by urologists with the hope of improvement of patient outcomes and satisfaction
