Diagnostic and operative arthroscopy of the shoulder joint has gained considerable importance in traumatology and orthopedic surgery over the last years. Injuries of the limbus glenoidalis, in particular traumatic shoulder luxation, injuries of the rotator cuff, infection of the glenohumeral joint and unclear posttraumatic pain are indications for diagnostic and operative arthroscopy. Arthroscopy of the shoulder is a procedure, which offers exact diagnosis and the possibility of immediate surgery at the same time. The technique of the shoulder joint arthroscopy has to be carried out carefully and according to a standard protocol. The complication rate of around 5% of shoulder arthroscopy has not to be neglected.
Despite the wide use of the international classification of megaureters, there is a lack of clear concepts especially for congenital malformations. We performed a follow-up study in 132 children with 171 megaureters operated on during the past 13 years. In 24 additional cases reconstructive surgery was not feasible due to advanced damaging of the parenchyma. In 97% of 171 megaureters, resection of the distal stenosis and ureterocystoneostomy was successful. In 20%, additional ureteric tailoring was necessary. Only one patient had recurrent reflux, and reoperation for recurrent stenosis was indicated in less than 2.5%. Urographic studies revealed that postoperatively 38% of calices resumed a normal appearance, whereas 80% of the ureters were of normal caliber and had normal peristaltic activity. From this study it is concluded that ureteric stenosis should be treated operatively in refluxing and obstructive cases. As a rule, correction of bladder or urethral pathology does not obviate the need for ureter surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
