Applications of indocyanine green-enhanced fluorescence in laparoscopic colorectal resections

AbstractRecently, Indocyanine Green (ICG)-enhanced fluorescence has been introduced in laparoscopic colorectal surgery to provide detailed anatomical informations. The aim of our study is the application of ICG imaging during laparoscopic colorectal resections: to assess anastomotic perfusion to reduce the risk of anastomotic leak, to facilitate vascular dissection when vascular anatomy of tumor site is unclear, and to identify ureter to prevent iatrogenic injury. After the transection, 5  ml of ICG solution is intravenously injected. A Full HD IMAGE1S camera, switching to NIR mode, in few seconds provides a real-time angiography of colonic perfusion. After anastomosis, another bolus is injected to confirm the anastomotic perfusion. When the tumor is localized in difficult site, the fluorescence provides a real-time angiography of tumor area vascularization to perform the vascular dissection. When the tumor is tightly attached to the ureter, the ICG solution injection through the catheter allows ureter identification. From November 2016, 38 patients were enrolled: ten left col ectomies, 22 right colectomies, three transverse resections, and three splenic flexure resections. In five cases, intraoperative angiography led to the identification of vascular anatomy. In one case the surgical strategy was changed. In one procedure, ureter identification allowed to prevent injury . Three postoperative complications that required surgical reoperation occured, of which one anastom...

AbstractPurposeTo present our experience of laparoscopic and robotic ureteroplasty using onlay flap or graft for the management of long proximal or middle ureteral strictures and summarize our treatment strategies for these challenging scenarios.MethodsFrom March 2018 to January 2020, 53 patients with long proximal/middle ureteral strictures (2 –6 cm) who underwent laparoscopic or robotic onlay flap/graft ureteroplasty were retrospectively enrolled. Different reconstruction techniques were chosen based on our management strategy: pelvic flap (PF) was the first choice for proximal stricture if pelvic tissue was s...

This study found that diabetes, postoperative stone residuals, urinary leukocytes ≧ 100 cells/HP, positive urine culture results, ureteral stent indwelling time ≧ 8 weeks, and high S.T.O.N.E. score were independent of AP associated with ureteral stent after PCNL risk factors andEscherichia coli is the main pathogenic bacteria and shows drug resistance.

Damage-associated molecular patterns (DAMPs) are released from tubular and interstitial cells in the kidney after unilateral ureteral obstruction (UUO). DAMPs are recognized by pattern recognition receptors (PRRs), which mediate the initiation of an immune response and the release of inflammatory cytokines. The animal model of UUO is used for various purposes. UUO in adult mice serves as a model for accelerated renal fibrosis, which is a hallmark of progressive renal disease. UUO in adult mice enables to study cell death, inflammation, and extracellular matrix deposition in the kidney. Neonatal UUO is a model for congenita...

ConclusionMasturbation and tamsulosin increased the spontaneous passage of distal ureteral stones 5 –10 mm in size. Masturbating at least 3–4 times a week was as effective as tamsulosin. Masturbation and tamsulosin also reduced the need for ureterorenoscopic lithotripsy.

Abstract Renal injury leads to chronic kidney disease for which women are not only more likely to be diagnosed with than men but have poorer outcomes as well. We have previously shown that expression of Sprr2f, a member of the Small Proline Rich Region (Sprr) gene family, is increased several hundred-fold after renal injury using a unilateral ureteral obstruction (UUO) mouse model. To better understand the role of Sprr2f in renal injury, we generated a Sprr2f knockout (Sprr2f-KO) mouse model using CRISPR-Cas9 technology. Sprr2f-KO female mice showed greater renal damage after UUO compared to wild type (Sprr2f-WT) ...

Limited information is available regarding complications associated with kidney-sparing ureteroscopic management of low-grade upper tract urothelial carcinoma (UTUC). To identify the associated complications rates and contributing factors, we examined data from relevant clinical studies. Thirty-eight publications (7 prospective, 31 retrospective;>1100 total patients) were identified. Ureteral stricture was the most frequent complication (studies; rates) (26/38; 0-27%), with incidence associated with number of procedures and treatment method.
