Epithelioid hemangioendothelioma is a distinct vascular tumor with low malignant biologic behavior that is very rare in the kidney. Only 3 adult patients have been reported to date in English-language reports. We report the case of a 9-year-old boy who presented with painless gross hematuria. Magnetic resonance imaging and positron emission tomography-computed tomography demonstrated a primary mass...
To assess the feasibility, safety, and efficacy of transperitoneal laparoscopic excision of primary seminal vesicle benign tumors (SVBTs) and summarize our experience with surgical techniques and follow-up outcomes of this rare condition.This study included 6 patients who underwent transperitoneal laparoscopic excision of primary SVBTs between June 2005 and April 2011. A 5-port transperitoneal approach...
To determine the spinal innervation and neuronal connections is important for studying renal metabolic responses. In this study, the spinal cords of 10 adult male C57BL/6J strain mice were mapped retrograde using injections of pseudorabies virus (PRV)-614. The virus, injected into the kidney, was specifically transported to the spinal cord. At 5 days after injection of the PRV-614, PRV-614–positive...
Primary tumors of the seminal vesicle are very rare. We reported a 35-year-old man with a rare primary diffuse large B-cell lymphoma of the seminal vesicles. By transrectal ultrasound (TRUS) imaging, ultrasonic elastography (UE), and computed tomography (CT) imaging, the tumor was defined to locate in seminal vesicles. By TRUS-guided biopsy and histopathological examinations, the patient was diagnosed...
To introduce our experience in using anatomic retroperitoneoscopic adrenalectomy (ARA) for adrenal tumors >5 cm and evaluate this procedure's safety and efficiency.Of the 1400 ARAs performed in the past 8 years, 110 were performed on patients who had adrenal tumors with a diameter >5 cm. The perioperative indexes of these patients were retrospectively collected and analyzed.The mean tumor size...
To present our surgical techniques and experience with retroperitoneal laparoscopic upper pole nephroureterectomy for a duplex kidney in adult patients without vesicoureteral reflux.A total of 32 adult patients with a duplex kidney underwent laparoscopic upper pole nephroureterectomy. A 3-port, finger- and balloon-dissecting, retroperitoneal approach was used. The upper pole renal parenchyma was divided...
To describe the technique of laparoscopic-assisted partial nephrectomy melded with open procedure in resection of postero-medial renal tumors.Six patients with postero-medial renal tumors were admitted between July 2008 and March 2009. They included 4 diagnosed renal cell carcinomas and 2 renal angiomyolipomas on preoperative imaging, and their tumors ranged from 2.5-4.3 cm in diameter. They underwent...
To present our surgical techniques and experience with retroperitoneal laparoscopic ureteroureterostomy in 10 patients with retrocaval ureter and review the data on the laparoscopic management of retrocaval ureter published in English.A total of 10 patients with retrocaval ureter underwent laparoscopic ureteroureterostomy. A 3-port, finger and balloon-dissecting, retroperitoneal approach was used...
Hypertension often persists after adrenalectomy for primary aldosteronism. Traditional factors associated with postoperative hypertension were evaluated, but whether genetic determinants were involved remains poorly understood. The aim of this study was to investigate the association of DNA polymorphisms within steroid synthesis genes (CYP11B2, CYP11B1) and the postoperative resolution of hypertension...
To compare the safety and efficacy of the 2-μm continuous wave (cw) laser vaporesection of the prostate with transurethral resection of prostate (TURP) in patients with symptomatic benign prostatic hyperplasia (BPH).In this prospective study, 100 patients with a prostate weight of < 80 g underwent 2-μm cw laser vaporesection (n = 58) or TURP (n = 42). Efficacy follow-up included measurement of...
To develop a staged laparoscopic training program for beginners to perform laparoscopic adrenalectomy (LA) and to determine its safety and feasibility.From January 2002 to October 2007, 5 beginners (postgraduate years 1-5) without previous experience in open adrenalectomy were selected randomly to receive the staged laparoscopic training, including box-trainer, animal model, and mentor-initiated clinical...
To investigate a novel and effective method to occlude the inferior vena cava (IVC) during surgical management of a renal tumor with a tumor thrombus extension into the IVC.We retrospectively reviewed the records of 10 patients with renal cell carcinoma or renal angiomyolipoma with tumor thrombus extending into the IVC who had undergone surgical intervention at our institute from May 2005 to May 2006...
To evaluate the effectiveness and safety of retroperitoneal laparoscopic adrenalectomy for pheochromocytoma and report our experience in adrenalectomy without previous control of the adrenal vein.From January 2000 to December 2005, 56 patients underwent 58 retroperitoneal laparoscopic adrenalectomy procedures for the treatment of pheochromocytoma. Adequate preoperative antihypertensive preparation...
To report our techniques and experience with retroperitoneal laparoscopic dismembered pyeloplasty for ureteropelvic junction (UPJ) obstruction. From May 2000 to September 2004, 50 patients with UPJ obstruction underwent laparoscopic dismembered pyeloplasty. A three-port, balloon-dissecting, retroperitoneal approach was used. All anastomoses were completed with free-hand intracorporeal suture techniques...
To evaluate the feasibility and clinical efficacy of retroperitoneal laparoscopic nephron-sparing surgery for renal tumors. Between June 2002 and February 2004, 11 cases of renal benign tumor and 21 cases of renal malignant tumor underwent enucleation of the tumor and wedge resection of the tumor through retroperitoneal laparoscopy, respectively. Tumor resection and hemostasis were mainly achieved...
