Laparoscopic ureterolysis with omental wrap for idiopathic retroperitoneal fibrosis

This is the case of a 60-year-old man who underwent a bipolar transurethral resection of the prostate (TURP) two years earlier. The patient developed a bladder neck sclerosis with a serious urinary obstruction and failure which was treated with two endoscopic procedures. Cystoscopy revealed a normal urethra right up to the bladder union. It was decided to perform an anterior reconstruction using a buccal mucosa graft in a transvesical laparoscopic technique.

Aim: This video aims to present the laparoscopic technique for right radical nephrectomy in detail. 

Case presentation: A 62-year-old man presented to our department with a one-week history of painless macroscopic hematuria. A preoperative abdominal CT-scan revealed a 6cm solid mass in the upper right kidney, originating from the renal cortex and extending into the renal pelvis. The patient was scheduled for a laparoscopic right radical nephrectomy. 

Discussion: The laparoscopic approach for kidney surgery has been well described in the literature, both for total and partial nephrectomies. The indications for the laparoscopic approach in kidney surgery has expanded to include grossly advanced tumors even with renal vein thrombosis. Several key steps are crucial for a smooth intraoperative progression and for optimal postoperative outcomes. 

Conclusions: The laparoscopic approach exhibits equivalent oncological outcomes, as well as a superior postoperative morbidity profile and should be the standard approach offered to all patients, especially with early carcinomas.

Adrenocortical carcinoma (ACC) is a rare disease in which malignant cancer cells form in the outer layer of the adrenal gland. The worldwide incidence of ACC is 0.5 to 2 per 1 million people annually (1). Adrenocortical carcinoma is also called cancer of the adrenal cortex. A tumor of the adrenal cortex may be functioning (i.e., makes more hormones than normal) or nonfunctioning (i.e., does not make more hormones than normal). Most adrenocortical tumors are functioning. The hormones produced by functioning tumors may cause certain signs or symptoms of disease (2). ACC can have protean clinical manifestations, including symptoms and signs of hormone excess and nonspecific symptoms as a mass effect of local tumor growth (3). However, an increasing number of ACC are identified in asymptomatic patients, as an incidental finding on imaging performed for other reasons (i.e., adrenal incidentalomas). The main treatment in non-metastatic cases is surgery (4). 

In this video, the authors present the case of a 58-year-old woman with a tumor identified in an adrenal topography as an incidental finding. The patient was oligosymptomatic since she presented with hypertension only. She also had undergone a robotic radical adrenalectomy using the Versius surgical robotic system (manufactured by CMR Surgical). Pathological findings revealed a massive lesion measuring 8.7 x 7.5 x 5.5cm, showing neoplasia of the adrenal cortex and suggesting a carcinoma with myxoid areas.

Robotic left adrenalectomy in a patient with adrenocortical carcinoma using the Versius robotic surgical system

Prostate cancer surgeons are commonly faced by a technically challenging situation dealing with prostate cancer having large median lobes. Patients with large median lobes often have larger prostates, which makes it difficult to visualize anatomical planes during robot-assisted radical prostatectomy (RARP) (1). The general consensus in the literature is that robotic assisted radical prostatectomy (RARP) for patients with a protruded median lobe (PML) poses a true technical challenge (2). A PML causes various degrees of distortion for bladder neck anatomy. Bladder neck resection in large median lobes involves a higher risk of ureteral orifice injury being too close to the bladder neck edge (3). PML has been associated with a longer operative time and hospital stay, and more blood loss. Additionally, poor recovery of urinary continence and higher positive surgical margins (PSMs) have been reported with PML (4). 

In this video, we present the case of a 59-year-old patient with an enlarged prostate and a protruded median lobe. The authors describe the steps and good results obtained from this challenging approach with the recent Versius surgical robotic system (manufactured by CMR surgical).
