The functional result two years after a microsurgical penile replantation. Case report.

We describe the technique of microsurgical penile replantation and a case followed up after two years. The patient was a young man with decompensated schizophrenia who emasculated himself with a kitchen knife. A particularly good functional result was achieved including restoration of sensation in the penile shaft and in the glans, and return of erectile capacity.

Diverticular of the male anterior urethra symptoms, diagnosis and treatment. A report on 12 cases.

Ventral and dorsal midline wide-mouthed diverticula and Cowper's perforate syringoceles were diagnosed in 12 men with symptoms such as post-voiding dribbling, dysuria, urethral discomfort and haematuria. In all cases the diagnosis was made during urethroscopy and most patients were treated at the same time with transurethral incision of the diverticular wall, thereby marsupializing the diverticulum into the urethra. Diverticula of the male anterior urethra are more common than has been hitherto assumed.

The natural course of prostatic carcinoma in relation to initial cytological grade.

We investigated retrospectively 91 patients with prostatic carcinoma diagnosed cytologically between 1978 and 1979. Of the patients 57 had no metastases (M0) at presentation. The majority of the patients without metastases had well or moderately well differentiated carcinoma.

Parathyroid morphology in gerbils after thyroidectomy and calcium administration.

Morphological studies of the parathyroid glands from adult Mongolian gerbils in which hypercalcaemia had been induced by thyroidectomy and calcium injections for 2-19 days were carried out. The potassium pyro-antimonate technique and subsequent X-ray analysis of the precipitates were used for ultrastructural localization of cations. Ultrastructurally, most (suppressed) chief cells exhibited a dense cytoplasm, medium-sized or large mitochondria, glycogen particles, inconspicuous endoplasmic reticulum and Golgi complex, calcium-containing precipitates mainly in mitochondria and nuclei, and sometimes also lysosomal bodies and accumulations of secretory granules which occasionally seemed to be discharged into cytoplasmic vacuoles.

The parathyroid glands of the Mongolian gerbil (Meriones unguiculatus).

The parathyroid glands of adult Mongolian gerbils were studied under an operation microscope, as well as with the aid of conventional light microscopy, and transmission and scanning electron microscopy. The mean serum level of calcium was 5.1 mEq/1 and that of phosphorus was 4.

Renal morphology in pigs with experimental hyperparathyroidism. Ultrastructural findings.

Ultrastructural examinations were performed in three groups of pigs; one sham-operated control group, one group subjected to thyroidectomy, and another group injected with parathormone after thyroidectomy (TX + PTH). Attention was mainly paid to the localization and structural details of the calcium deposits which were found in the TX + PTH group 78 and 150 hours after the first PTH injection. Calcium deposits were found in the epithelial cells and lumina of the tubular system, especially in the proximal convoluted tubules.

Renal morphology in pigs with experimental hyperparathyroidism. Light-microscopic findings and some functional aspects.

Light-microscopic examinations were performed in three groups of pigs; one sham-operated control group, one group subjected to thyroidectomy (TX), and one group injected with parat-hormone (PTH) after thyroidectomy (TK + PTH). The kidneys of the sham-operated animals were normal, whereas slight to moderate dilatation of some tubules was seen in the TX group. The most prominent changes in the TX + PTH group were calcium deposition, tubular dilatation and degeneration, inflammation, and hyperaemia.

Dysplasia of the testis and epididymis.

Various congenital malformations of the testis and the seminal pathways are illustrated by 10 cases. Though these malformations are often free from symptoms, an increasing number of them are now being discovered in connection with investigations of male infertility. In cases of azoospermia where testicular biopsies show complete spermatogenesis, surgical exploration is indicated.
