Retroperitoneoscopic enucleation adrenalectomy: a viable surgical option for small nonsecreting adrenal tumors with low potential of malignancy.

Laparoscopic total adrenalectomy has become the standard treatment for adrenal mass. Meanwhile, there has been a growing trend toward laparoscopic adrenal-sparing surgery worldwide to avoid the risk and potential complications of adrenal insufficiency. The objectives of this study were to describe a retroperitoneoscopic adrenal tumor enucleation technique, to assess the clinical outcomes of this technique in the treatment of 20-40 mm nonsecreting adrenal tumor (NAT) with low potential of malignancy, and to provide a feasible choice for patients who have preference on resection.

Efficacy and feasibility of day surgery using transurethral seminal vesiculoscopy under caudal block anesthesia for intractable hemospermia.

Background: Transurethral seminal vesiculoscopy (TSV) is a safe and effective method for intractable hemospermia. It uses a natural cavity, is fast, involves little trauma, and boasts a low incidence of complications. Because uncontrollable penile erection during general anesthesia will severely influence the surgical operation or even damage the endoscope, spinal anesthesia was applied more on TSV.

Metallic ureteral stent in restoring kidney function: Nine case reports.

Background: Retroperitoneal fibrosis is an exceptionally rare disease characterized by proliferation of fibrous tissue and inflammation in the retroperitoneum. It features many symptoms in the kidneys and in other organs and usually leads to ureteral obstruction.

Case Summary: Here we present 9 consecutive cases of idiopathic retroperitoneal fibrosis (IRPF) in patients who presented to the Department of Nephrology or Department of Rheumatology, Xuanwu Hospital, Capital Medical University, Beijing, China, between January 2012 and June 2017 with ureteral obstruction due to external compression of the ureter that led to hydronephrosis and kidney dysfunction.

Nephron sparing endoscopic treatment for primary carcinoma of the renal calyx: A case report and literature review.

Primary carcinoma of the renal calyx is extremely rare. The present study reported nephron sparing endoscopic treatment for primary carcinoma of the renal calyx. An 81-year-old female presented with a 1-year history of intermittent painless gross hematuria.

Genetic Variations in Inflammatory Response Genes and Their Association with the Risk of Prostate Cancer.

Prostate cancer is a common cancer in men. Genetic variations in inflammatory response genes can potentially influence the risk of prostate cancer. We aimed to examine the association between PPARG Pro12Ala, NFKB1 -94 ins/del, NFKBIA -826C/T, COX-1 (50C>T), and COX-2 (-1195G>A) polymorphisms on prostate cancer risk.

Comparison between extracorporeal shock wave lithotripsy and ureteroscopic lithotripsy for treating large proximal ureteral stones: a meta-analysis.

Objective: To compare extracorporeal shock wave lithotripsy (ESWL) and ureteroscopic lithotripsy (URSL) in terms of efficacy, complications, and overall efficiency in the management of proximal ureteral calculi. ESWL and URSL are the 2 most common modalities for treating ureteral stones. Previous studies and meta-analyses suggest that for stones <10 mm, ESWL is safer and of comparable efficacy compared with URSL.

Histological and mechanical properties of autologous living tissue biotubes.

The aim of this study was to explore and evaluate biotubes consisting of autologous tissues. The biotubes were prepared by intra-abdominally embedding silicon rods as moulds. The specimens were analyzed by mechanical tests, histological observation and superficial study.

[Application of neoadjuvant hormonal therapy in (125)I permanent seed implantation for prostate cancer].

Objective: To explore the therapeutic response and toxicity of neoadjuvant hormonal therapy in (125)I permanent seed implantation for prostate cancer and validate the clinical efficacy of neoadjuvant hormonal therapy.

Methods: A total of 165 patients with T1c-T3b prostate cancer received transperineal ultrasound-guided (125)I permanent seed implantation and neo-adjuvant hormonal therapy (NHT). Their median age was 79 years (range: 65 - 88).

Thulium laser vaporesection versus standard transurethral resection of the prostate: a randomized trial with transpulmonary thermodilution hemodynamic monitoring.

Objectives: To characterize the hemodynamics comparing thulium laser vaporesection of the prostate with traditional transurethral resection of the prostate.

Methods: A total of 80 consecutive patients with benign prostatic hyperplasia were randomly assigned into the thulium laser vaporesection of the prostate group or transurethral resection of the prostate group. Transpulmonary thermodilution hemodynamic monitoring was used before and 1 h after surgery to assess patient hemodynamics.

Novel biologic model for percutaneous renal surgery learning and training in the laboratory.

Objectives: To improve the learning and training of percutaneous renal access and intrarenal procedures with a biologic porcine kidney model.

Methods: We set up a biologic bench model using a porcine kidney. The kidney was wrapped in a full-thickness skin flap with subcutaneous fascia and muscle and fixed to a wooden board with 2 long steel nails.

[Comparative study of laparoscopic partial nephrectomy and traditional open procedure: analysis of 26 cases].

Objective: To evaluate the feasibility and technique points of laparoscopic partial nephrectomy in the treatment of malignant renal tumor.

Methods: 26 patients with malignant renal tumor underwent partial nephrectomy over the past 5 years, including 11 cases treated with laparoscopic partial nephrectomy, with the mean tumor size of 2.4 cm (1.
