Short- and long-term outcomes of kidney transplants with kidneys lavaged by retrograde perfusion technique.
Chronic Dis Transl Med
September 2015
Objective: To evaluate the clinical safety and efficacy of the retrograde perfusion technique in kidney transplantation.
Methods: Between January 2001 and June 2011, 24 cases of kidney transplantation with kidneys perfused using the retrograde perfusion technique due to renal artery variations or injury were selected as the observation group (retrograde perfussion group, RP group). Twenty-two cases of kidney transplantation via conventional perfusion were chosen as the control group (antegrade perfussion group, AP group).
Purpose: To present our surgical techniques and experiences of retroperitoneal laparoscopic nephroureterectomy for the treatment of tuberculous nonfunctioning kidneys.
Materials And Methods: From March 2005 to March 2013, a total of 51 patients with tuberculous nonfunctioning kidney underwent retroperitoneal laparoscopic nephroureterectomy at our medical center. The techniques included early control of renal vessels and dissection of the diseased kidney along the underlying layer outside the Gerato's fascia.
Sarcomatoid carcinoma is a high-grade malignant neoplasm which exhibits morphological and/or immunohistochemical evidence of bidirectional epithelial and mesenchymal differentiation. Sarcomatoid carcinoma occurring in the upper urinary tract is rare. The present study reports a case of primary sarcomatoid carcinoma of the renal pelvis.
View Article and Find Full Text PDFObjective: To assess the mid-long-term efficacies of orthotopic urinary diversion in women.
Methods: From February 2003 to August 2012, 28 female patients with bladder cancer underwent radical cystectomy and orthotopic ileal neobladder.Open (n = 18) and laparoscopic (n = 9) procedures were performed.
Background: Laparoendoscopic single-site (LESS) surgery through the retroperitoneal approach has been seldom reported. We aimed to evaluate the outcomes of LESS and conventional laparoscopic surgery via the retroperitoneal approach in the management of large, impacted ureteral calculi.
Methods: Between November 2011 and July 2013, retroperitoneal LESS ureterolithotomy was performed in 12 patients using a homemade single-port device comprising a surgical glove and several strips of tape.
Purpose: To present our surgical techniques for retroperitoneal laparoendoscopic single-site (LESS) pyelopyelostomy for retrocaval ureter and our initial experience with this method in 4 patients.
Methods: From June 2010 to May 2011, 4 patients with retrocaval ureter underwent retroperitoneal LESS pyelopyelostomy with a homemade single-port device and standard straight laparoscopic instruments. The single-port device was made with a surgical glove and Foley catheter and allowed the introduction of three trocars.
[A novel technique of ureterointestinal anastomosis for urinary diversion].
Zhonghua Yi Xue Za Zhi
January 2012
Objective: To introduce a novel technique of ureterointestinal anastomosis for urinary diversion and report the preliminary clinical data.
Methods: Between June 2007 and June 2011, a total of 50 patients underwent radical cystectomy and ileal neobladder for invasive bladder carcinoma or carcinoma in situ. A novel, separate and direct end-to-end technique for ureteral reimplantation to the entrance of a segment of ileum was applied.
Objective: To evaluate the value of intraoperative laparoscopic ultrasonography (ILUS) in retrolaparoscopic nephron-sparing surgery.
Methods: A total of 81 cases were studied during a 5-year period: 38 patients with a benign renal tumor who underwent enucleation of the tumor and 43 patients with a suspected malignant renal tumor who underwent wedge resection of the tumor. ILUS was used to evaluate renal perfusion, locate the tumor, precisely delineate the tumor border, characterize the tumor, and look for any suspected satellite renal masses.
Objective: To summarize the preliminary experiences of 13 cases of laparoscopic radical cystectomy and construction of orthotopic T pouch ileal neobladder and evaluate the oncological and functional outcomes of this procedure.
Methods: From August 2005 through July 2009, 13 patients underwent radical cystectomy and standard lymphadenectomy followed by construction of orthotopic T pouch ileal neobladder via mini-laparotomy for muscular invasive bladder cancer. The data were analyzed according to procedure time, blood loss volume, transfusion volume, number of dissected lymph nodes, peri-operative complications, morphology and function of upper urinary tract and status of urinary continence.
Objective: To evaluate the urodynamics and functions of upper urinary tract in a substitute of orthotopic T pouch ileal bladder.
Methods: From June 2004 through September 2009, 90 patients underwent the construction of an orthotopic T pouch ileal neobladder after radical cystectomy for muscle-invasive bladder cancer. The radiographic or ultrasound evaluation of upper urinary tract, determination of renal functions and urodynamic evaluation of T pouch ileal neobladder were performed by data analysis.
Objective: To investigate the clinical efficacy and safety of combining pneumatic and ultrasonic power during PCNL.
Methods: From Sep 2003 to Aug 2005, we treated 486 patients (509 kidneys) by combining pneumatic and ultrasonic power during percutaneous nephrolithotomy. Clinical data were analyzed retrospectively.
Objective: To evaluate the efficacy and safety of management of renal stone in non-dilated collecting system by percutaneous nephrolithotripsy (PCNL) under ultrasound guidance.
Method: From September 2003 to April 2005, 132 cases of renal stone in non-dilated collecting system were performed by percutaneous nephrolithotripsy. A stent was first inserted into the pelvis through cystoscope, and saline was instilled to dilate collecting system.
