We present a case of ureteropelvic junction obstruction secondary to aberrant crossing gonadal vessels in a symptomatic 11-year-old female with horseshoe kidney, treated with a robotic-assisted pyeloplasty.
The patient presented with intermittent right-sided flank pain and vomiting. Renal ultrasound showed right-sided hydronephrosis and an abnormal-shaped kidney. MAG-3 renal scan demonstrated decreased function of the right kidney and no drainage. A MR Urogram showed a horseshoe type kidney with malrotation and an anterior dilated renal pelvis.
The patient underwent a robotic-assisted dismembered pyeloplasty. Intraoperatively, the right kidney was confirmed to be malrotated with a large, anteriorly directed renal pelvis. A packet of aberrant crossing gonadal vessels was identified and dissected from the right ureter and surrounding tissue. The ureter was sharply divided at the level of the ureteropelvic junction and transposed above the crossing vessels. A tension free mucosal to mucosal water-tight anastomosis was performed starting at the apex of the incision. A double-J stent was introduced into the ureter. The remainder of the anastomosis was completed with interrupted sutures. There were no intraoperative or postoperative complications.
Robotic-assisted dismembered pyeloplasty is a safe and effective method for UPJO correction in symptomatic patients with complex renal anatomy.
Partial penectomy is the surgical standard of care for invasive tumors of the mid to distal penis, but is utilized in cases of distal penile calciphylaxis due to pain. Partial Penectomy is advantageous compared to a total penectomy, as the patient is able to urinate in the standing position.
A 51-year-old man on dialysis for end stage renal disease presented to the emergency department with pain that was increasing in severity for over a month at the glans of the penis. On examination, the glans of the penis was firm with gangrenous necrosis extending distal to the corona, and the urethral meatus was not identified due to the extensive scarring. A clinical diagnosis of penile calciphylaxis was determined and a Partial Penectomy was subsequently performed. Calciphylaxis is a rare life-threatening systemic disease in patients with end stage renal disease due to medial calcification and fibrosis of blood vessels leading to infection and gangrene. The prognosis for penile calciphylaxis tends to be poor with an overall mortality of 64% with a mean time to death of 2.5 months.
This video describes step by step a new surgical technique for performing “Open Anterograde Anatomic Radical Retropubic Prostatectomy” (R2PA2) for the treatment of prostate cancer in the same way as performed by the robot, without the need for using the robotic platform, video or any equipment other than those used in the conventional open surgery described by Patrick Walsh in 1983. This prospective and randomized study is registered in the ClinicalTrials.gov identifier number: NCT02687308, and the full description of this technique was published in: Fabricio et al., Surgery Curr Res 2017, 7:5

In this video, we demonstrate the set-up, port configuration, and key steps involved in performing a robotic-assisted retroperitoneoscopic partial nephrectomy.

Pelvic lymphadenectomy is part of most gynecologic malignancy staging procedures. Knowledge of the retroperitoneal anatomy is key to safely completing this procedure.
