Since October, 1980, we have used transurethral fulguration of the diverticular mucosa and incision of the diverticular neck in combination with electrohydraulic lithotripsy of bladder stones and transurethral prostatic resection to treat all aspects of diverticula in 11 patients. In comparing the results with those of open diverticulectomy, we found the transurethral procedure to be equally effective while being safer, faster, and less expensive.

Ureteral obstruction by an extrinsic object is rare. We herein report a case of renal colic caused by a shotgun pellet lodged in the ureter seven years after the injury. Computerized tomography scan and antegrade pyelogram demonstration were obtained.

Comparative Study
Sources of fibrinogen for coagulum pyelolithotomy, without thrombin. A comparative study.
Coagulum pyelolithotomy without the use of thrombin is simplified by using single donor plasma, fresh frozen plasma, and "maxi-cryoprecipitate" (expanded cryoprecipitate) as sources of fibrinogen. The physical properties, including generation time, breaking point, and tensile strength were compared for different coagula. An illustrative case is presented for each fibrinogen source. ⋯ The preferred source of fibrinogen is cryoprecipitate followed by maxi-cryoprecipitate and fresh frozen plasma in that order. Twenty parts of fibrinogen to one part of 10 per cent calcium chloride provided the shortest generation time and the greatest tensile strength in each of the experiments, and is used exclusively by the authors at present. Single donor plasma is not recommended as a source of fibrinogen for coagulum generation clinically.

Traumatic dislocation of the testis is a rare disorder with only 46 cases having been reported. We herein add 3 cases. ⋯ Its mechanism, classification, diagnosis and pathology are discussed. Early closed reduction or surgical orchiopexy is recommended.
