Objectives: To describe our preferred method of right laparoscopic live donor nephrectomy (LDN) using a retroperitoneoscopic approach to determine the indications for, and overall rate of, right LDN and to compare the donor and recipient early outcomes of right retroperitoneal LDN to those of left transperitoneal LDN in a consecutive single-institution series.
Methods: At our institution, LDN for allotransplantation was performed in 143 consecutive patients. The indications for right LDN (n = 29) included multiple left renal vessels (n = 18), early branching of the left renal artery (n = 1), left renal vein anomaly (n = 2), right renal arterial fibromuscular dysplasia (n = 2), right renal cyst (n = 3), mild right hydronephrosis with delay on renal scan (n = 1), or right nephrolithiasis (n = 2).
Results: Right LDN was performed in 29 (20.3%) of 143 patients using a retroperitoneal approach in all but the first case. Right retroperitoneal LDN was associated with decreased blood loss and operative time compared with left transperitoneal LDN. The hospital stay, analgesic use, and donor serum creatinine at discharge were similar in both groups. Despite a statistically significantly increased warm ischemia time and decreased renal vein length, right retroperitoneal LDN was associated with recipient functional outcomes at 5 and 30 days after transplant that were no different from those after left transperitoneal LDN.
Conclusions: Right retroperitoneal laparoscopic LDN provides similar donor and recipient outcomes when compared with the left transperitoneal approach and obviates most of the technical challenges encountered with a right transperitoneal approach.

Diaphragmatic pheochromocytoma: Two case reports and a review of the literature.
Medicine (Baltimore)
December 2024
Department of Urology, Gansu Provincial Hospital, Lanzhou, China.
Rationale: Pheochromocytomas typically arise in the adrenal medulla, whereas ectopic pheochromocytomas/paragangliomas commonly occur near the abdominal aorta, bladder, mediastinum, and head. Diaphragmatic pheochromocytomas are exceedingly rare, and there is limited surgical experience with their treatment.
Patient Concerns: In Case A, the subject is a 45-year-old male, while in Case B, the subject is a 59-year-old female.

Introduction & Objectives: The use of transperitoneal robotic-assisted procedures for ureterovesical junction (UVJ) anomalies in pediatric patients is increasing. However, the extra-peritoneal approach potentially less invasive, remains underexplored with robotic approach in pediatric patients. We present our experience of robot-assisted extra-vesical laparoscopic extra-peritoneal UVJ surgery.

Persistent Müllerian duct syndrome (PMDS) is a rare kind of internal male pseudohermaphroditism. The patient, who has a male karyotype and phenotypic characteristics, exhibits Müllerian duct derivatives such as the uterus, cervix, fallopian tubes, and upper two-thirds of the vagina. This article provides a comprehensive analysis of the CT and MRI characteristics of a case of PMDS in a 35-year-old male patient who sought medical attention at our clinic due to pain in the left inguinal region and the presence of undescended testes on both sides.

This retrospective study highlights the safety, efficacy, and feasibility of performing transperitoneal laparoscopic pyelolithotomy in cases of pelvic ectopic kidney. Methodology The 15 patients with ectopic pelvic kidneys and nephrolithiasis underwent laparoscopic pyelolithotomy.

Aim: A minimally invasive surgery (MIS) extraperitoneal (XP) approach to left-sided colorectal resection utilizing the laparoscopic approach has recently been shown to be safe and feasible and to have potential advantages over the transperitoneal approach, especially in high-risk surgical patients. The aim of this article is to provide a first cadaveric demonstration of the use of a single-port robotic platform in performing XP low anterior resection by MIS.
Method: A single-port robotic platform (DaVinci®SP™) was used to perform XP single-port low anterior resection in two cadavers with body mass indexes (BMIs) of 19 and 40 kg/m.
