Case ReportsSuccessful repair of huge bladder diverticulum with a transurethral fulguration. Report of a case.
We present a 68-year-old man with a huge bladder diverticulum associated with benign prostate hypertrophy treated with transurethral fulguration of the diverticular mucosa in combination with transurethral resection of the prostate. The procedure was well tolerated by the patient and unfavorable symptoms faded after this procedure. Follow-up cystogram demonstrated remarkable reduction of the diverticulum.

Ultrasonic Doppler and duplex systems: possibilities and limitations.
In order to utilize Doppler modalities in an optimal manner, one should both be aware of their potential and respect their limitations. To this end, a variety of technical and physical factors affecting the performance of Doppler devices are discussed: (1) the velocity of propagation limiting the temporal resolution of pulsed systems; (2) intervening tissue that may weaken the echo considerably; (3) the size of the sample volume that could be too small to provide a transvascular mean velocity or too large to discriminate flow in adjacent vessels; (4) the principles of continuous wave mode lacking depth resolution, and pulsed mode being prone to aliasing; (5) the additional complexity of duplex/triplex systems; (6) the tight temporal restrictions of 2-dimensional color mappers which cause poor velocity resolution, and (7) the angle of incidence that needs to be assessed in order to measure absolute velocity and the cross-sectional area that must be measured additionally for the calculation of the volume flow rate. Based on this discussion, some hints on selecting instruments or instrument parameters are given.

Case ReportsSpontaneous rupture of adrenal pheochromocytoma: a case report.
A case of right adrenal pheochromocytoma was described which presented as an acute abdominal emergency and resulted in shock due to spontaneous rupture into the retroperitoneum. Spontaneous remission of clinical symptoms followed and the tumor was safely resected later. Scintigraphic imaging using 131I-metaiodobenzylguanidine clearly demonstrated the tumor when endocrinological examinations were within normal ranges.

Case ReportsPheochromocytoma presenting as shock and followed by spontaneous remission.
A case of pheochromocytoma presenting as an acute abdominal emergency with shock is described. Shock was followed by transient hypertensive crisis and thereafter by spontaneous remission of clinical symptoms. The surgically removed tumor showed extensive necrosis.

Case ReportsBlind-ending branch of bifid ureter. Report of 2 cases in children.
2 new cases of blind-ending branches of bifid ureters in children are reported. Clinical and diagnostic features as well as treatment of this pathology are presented. The authors emphasize the differential diagnosis of blind-ending ureteral diverticula, suggesting the possibility that the single congenital diverticulum is actually a dilated blind-ending ureter.
