Open radical prostatectomy reproducing robot-assisted radical prostatectomy: Involving antegrade nerve sparing and continuous anastomosis
<div><p>ABSTRACT Purpose: To present modified RRP using the same method as RALP and compare its surgical outcomes with RALP. Materials and Methods: Demographics, perioperative and functional outcomes of the 322 patients that underwent RRP (N=99) or RALP (N=223) at our institution from January 2011 through June 2013 were evaluated retrospectively. Postoperative incontinence and erectile dysfunction are involved functional outcomes. During the modified procedure, the bladder neck was dissected first as for RALP. After dissection of vas deference and seminal vesicle, the prostate was dissected in an antegrade fashion with bilateral nerve saving. Finally, the urethra was cut at the prostate apex. After a Rocco suture was applied, and then urethrovesical anastomosis was performed with continuous suture as for RALP. Results: Perioperative characteristics and complication rates were similar in the RRP and RALP groups except for mean estimated blood loss (p<0.001) and operative time (p<0.001). Incontinence rates at 3 and 12 months after RRP decreased from 67.6% to 10.1 and after RALP decreased from 53.4% to 5.4%. Positive surgical margin rates were non-significantly different in the RRP and RALP groups (30.3% and 37.2%, respectively). Overall postoperative potency rate at 12 months was not significant different in RRP and RALP groups (34.3% and 43.0%). Conclusions: RRP reproducing RALP was found to have surgical outcomes comparable to RALP. This technique might be adopted by experienced urologic surgeons as a standard procedure.</p></div

Biomimetic Porous PLGA Scaffolds Incorporating Decellularized Extracellular Matrix for Kidney Tissue Regeneration
Chronic kidney disease is now recognized
as a major health problem, but current therapies including dialysis
and renal replacement have many limitations. Consequently, biodegradable
scaffolds to help repairing injured tissue are emerging as a promising
approach in the field of kidney tissue engineering. Poly(lactic-<i>co</i>-glycolic acid) (PLGA) is a useful biomedical material,
but its insufficient biocompatibility caused a reduction in cell behavior
and function. In this work, we developed the kidney-derived extracellular
matrix (ECM) incorporated PLGA scaffolds as a cell supporting material
for kidney tissue regeneration. Biomimetic PLGA scaffolds (PLGA/ECM)
with different ECM concentrations were prepared by an ice particle
leaching method, and their physicochemical and mechanical properties
were characterized through various analyses. The proliferation of
renal cortical epithelial cells on the PLGA/ECM scaffolds increased
with an increase in ECM concentrations (0.2, 1, 5, and 10%) in scaffolds.
The PLGA scaffold containing 10% of ECM has been shown to be an effective
matrix for the repair and reconstitution of glomerulus and blood vessels
in partially nephrectomized mice in vivo, compared with only PLGA
control. These results suggest that not only can the tissue-engineering
techniques be an effective alternative method for treatment of kidney
diseases, but also the ECM incorporated PLGA scaffolds could be promising
materials for biomedical applications including tissue engineered
scaffolds and biodegradable implants
