Purpose. We reviewed our 20 years of experience and the current literature regarding the long-term outcome of endoscopic treatment of vesicoureteric reflux (VUR) using the different tissue bulking substances with a special emphasis on the long-term efficacy. Material and Methods. Our own experience and the current literature on the long-term results after(More)
Purpose. In recent years, endoscopic injection became the procedure of choice for the correction of vesicoureteral reflux in the majority of the centers. Unfortunately, endoscopic treatment is not always successful and sometimes requires more than one trial to achieve similar results to that of an open reimplantation surgery. Our aim of this study is to(More)
PURPOSE To review the evolution of the technique of hypospadias repair. METHODS A search of Pubmed, Medline and the Journal of Pediatric Urology was performed, and papers dealing with surgical techniques for hypospadias repair were critally reviewed. Special emphasis was given to papers on the effects in the long term of hypospadias repair on voiding and(More)
AIMS The morphology and functional importance of the autonomic nervous system in the upper urinary tract is still not completely understood. Previous histological studies investigating the innervation of the urinary tract have mainly used conventional sections in which the three-dimensional structure of the intramural innervation is difficult to achieve. In(More)
The role of the autonomic innervation of the upper urinary tract for pyeloureteral motility is not completely understood. It is still debatable if the autonomic nervous system might play a modulating role on the ureteral peristalsis. The aim of this study was to investigate the distribution and regional variation of the intramural innervation using(More)
To investigate the distribution of nitrergic and cholinergic innervation in rabbit, pig, and human upper urinary tract, (UUT) whole-mount preparations and frozen sections were stained with nicotinamide adenine dinucleotide phosphate (NADPH)-diaphorase and acetylcholinesterase (AChE) histochemistry. NADPH-diaphorase and AChE staining demonstrated two(More)
