Feasibility of Simultaneous Bilateral Endoscopic Surgery in Prone Split-Leg Position for Bilateral Upper Urinary Tract Calculi: A Pilot Study.

Introduction: We explored the viability of simultaneous bilateral endoscopic surgery (SBES) in the prone split-leg position for managing bilateral calculi.

Methods: We retrospectively reviewed 72 patients who underwent SBES, with procedures involving ureteroscopy (URS) and contralateral percutaneous nephrolithotomy (PNL) simultaneously, in prone split-leg position.

Results: Operative times averaged 109.

Current Trends in Percutaneous Nephrolithotomy in China: A Spot Survey.

Objective: To describe trends in the procedure of percutaneous nephrolithotomy (PCNL) in China to identify training needs.

Methods: A spot survey with 36 questions, which revealed demographic data, patterns of PCNL practice, and opinions regarding specific clinical cases, was administered to Chinese urologists during the 17 National Urological Urolithiasis Symposium held in Dandong in 2018.

Results: Out of 400 participants, 221 responses to the survey were received.

Microperc with Self-Assembled Fr 4.85 Visual Needle and Ureteral Access Sheath.

Background: Micropercutaneous nephrolithotomy (microperc) is the least invasive among percutaneous nephrolithotripsy (PCNL) procedures. Although microperc has a high stone-free rate and certain advantages over other methods, modifications may be needed to improve the technique. We describe our experience performing microperc using a self-assembled visual needle and ureteral access sheath (UAS).

Urinary fractalkine is a marker of acute rejection.

Chemokines and their receptors play an important role in the development of allograft rejection through directing mononuclear cell invasion of the graft. To study whether chemokine assays in the urine could prove to be predictive of acute rejection, we measured the urinary excretion of several chemokines, including fractalkine, chemokine monokine induced by interferon-gamma, interferon-gamma-inducible protein 10, macrophage inflammatory protein-3 alpha, granzyme B, and perforin in 215 allograft recipients and in 80 healthy control subjects. The 67 patients with acute rejection had significantly higher levels of all urinary chemokines compared to the healthy controls or patients having chronic allograft nephropathy but with stable renal function.

Acute renal allograft rejection is associated with increased levels of vascular endothelial growth factor in the urine.

Aim: The purpose of this study was to assess whether measurement of urinary vascular endothelial growth factor (VEGF) could be adopted as a new non-invasive diagnostic tool for acute rejection following renal transplantation.

Methods: Urinary concentration of VEGF was determined by an enzyme-linked immunosorbent assay technique in 215 renal allograft recipients and 80 healthy controls.

Results: Subjects with acute rejection (n=67) excreted urinary VEGF at a significantly higher level (28.

[Changes of gap junction in penile cavernous smooth muscle cells of hypertensive rats].

Objective: To compare the changes of the intercellular conjunction in penile cavernous tissues between spontaneously hypertensive rats (SHR) and normotensive ones, and to study the relation of blood pressure with erectile function.

Methods: After apomorphine (APO) injection, we observed penile erections in SHR (SHR group, n=5) and Wistar-Kyoto rats (WKY group, n=5), studied the ultrastructure of the cell-to-cell conjunction between the penile cavernous smooth muscle cells with a transmission electrical microscope, and examined the expression of mRNA and Connexin 43 protein by RT-PCR and immunohistochemistry.

Results: The erectile frequency in the SHR group was significantly lower than in the WKY group.

[Testicular tumor in Mongolian men (report of 35 cases)].

Objective: To improve the diagnosis, therapy and prognosis of testicular tumor in Mongolian men.

Methods: A retrospective review of 35 cases of testicular tumors in Mongolian men from seven medical centers dated from 1990 to 2004 was performed.

Results: The usual presentation of a testicular tumor was a nodular or painless swelling of one gonad.
