Extracorporeal shockwave lithotripsy of ureteral stone in a patient with en bloc kidney transplantation: a case report.

We report a case of ureterolithiasis in a patient with an en bloc kidney transplantation, using extracorporeal shockwave lithotripsy (ESWL). The patient presented with asymptomatic macrohematuria. Computed tomography revealed a ureteral calculus just below the pyeloureteral junction with hydronephrosis of the medially positioned kidney. Took two sessions of ESWL were required for complete disintegration of the stone. At 3 years after successful treatment, the patient has an excellent functioning and stone-free graft.

Vascular complications after 725 kidney transplantations during 3 decades.

Among 725 renal transplantations, the most common vascular complication was arterial stenosis, which was observed in 23 patients (3.17%). The majority of 20 (6.49%) arterial stenoses appeared in our initial experiences when we routinely used end-to-end renal graft to internal iliac artery anastomoses. A significant reduction in this incidence (0.72%) was achieved by introducing end-to-side anastomoses of the renal graft artery to the external or common iliac arteries. Intractable hypertension or impaired renal function in 14 patients (60.87%) with arterial stenosis demanded treatment. Patch angioplasty was more successful than other methods. The limited possibilities of conservative treatment of arterial hypertension at that time were the main reason for this frequent surgical repair. Among other vascular complications, the most serious were 12 episodes of arterial bleeding in 10 patients. Five kidneys were lost because of ruptured arterial anastomoses. In 6 patients, the common or external iliac artery was ligated as to achieve hemostasis with acute arterial insufficiency of the lower extremity in 4 patients. One patient required leg amputation, whereas 2 underwent extra-anatomic bypass procedures and 1 died because of hepatic failure. The majority of vascular complications occurred in the initial period of our transplantation practice. However, in spite of progress in diagnostic and treatment options, vascular complications may cause considerable clinical problems.

[Lethal rupture of an echinococcal cyst of the liver]. / Perforation eines Leberechinokokkus mit Todesfolge.

A 50-year-old man is admitted to the hospital emergency service because of a 24-hour history of right abdominal pain. Ultrasound examination and laboratory tests suggest the perforation of an Echinococcal cyst situated in the subcapsular area of the right hepatic lobe. The patient and his family refuse the recommended hospitalisation and operation and leave the hospital on their own responsibility. 60 hours later the patient dies. Post-mortem examination confirms the diagnosis of a perforated hydatid cyst of the right hepatic lobe. The cause of death was a partly fibrino-purulent, partly nodular peritonitis including the area of liver rupture.

The analysis of population structure based on morphometric dimensions of metacarpal bones (the Island of Krk, Croatia).

The aim of this study was to investigate: 1) a possibility of using the morphometric dimensions of metacarpal bones for approximation of biological distances, and 2) a relationship of biological matrices, based on the morphometric dimensions of metacarpal bones to other biological (dermatoglyphic, genetic), bio-cultural (migration) and geographic variables. The morphometry of the metacarpal bones was performed according to Barnett and Nordin procedure and biological distances were estimated using Mahalanobis D2 method. Population structure was assessed through Mantel's permutation test using E2 genetic distances for classical serogenetic markers, DA genetic distances for HLA, DSW genetic distances for STRs, geographic distances expressed in kilometres, and migration kinship matrix estimated according to the method proposed by Malécot and modified by Morton. This study clearly indicated the need for applying factorial analytical approach to study the factor structure of morphometric variables that may be measured on six metacarpal bones as well as the need for conducting complex family and segregation analyses to address not only the intriguing issue of genetic vs. ecological impact onto the bone mineral turnover, but also to test the hypothesis of major gene control in determining bone mineral density.

Morphometric dimensions of metacarpal bones in the population structure analysis (island of Krk, Croatia).

The population structure analysis by means of the osteometric dimensions of metacarpal bones in the population groups of the northern Adriatic island of Krk, Croatia was performed. The sample consisted of randomly sampled adult islanders (94 males and 79 females) aged from 18 to 85 years from six villages of the island of Krk. "Biological distances" were estimated by the Mahalanobis D2 analysis for bone length (L), total diaphysis width (T) and medullary canal width (M) dimensions of the second left metacarpal bone. Analysis of the osteometric dimensions of metacarpal bones as a measure of biological distance between population groups of the island of Krk indicated bio-cultural and socio-cultural events, rather than geographical distances, to be the primary determinants of anthropogenetic structure of today's population groups of the island.
