Surgical treatment of the static perineal modifications in spinal cord or cauda equina lesions.

Severe dysuria, due to insufficiency of the perineal floor associated during micturition with a posterior tilting of the prostate-bladder block in lower or in associated upper and lower motor neuron lesions, can be treated surgically by a prostato cytso pexy. Since 1971, eight patients with post-traumatic conus and/or cauda equina lesions have been treated by this intervention. On the follow-up the satisfactory results appear to remain stable.

[The silent kidney. Evolving ultrasonic picture of emphysematous pyelonephritis: the vanishing kidney. Apropos of a case].

The authors report the progressive disappearing of the sonographical image of a previously visualized kidney in a case of emphysematous pyelonephritis. They have called the sonographic vanishing kidney "the sign of the Deaf Kidney". The non-visualisation of a kidney with advanced emphysematous pyelonephritis is due to the infiltration of the perirenal environment by a gas envelope and the filling of the excretory cavities by gas.

[Invasive cancer of the prostate. Reconstruction of the lower urinary tract by prostatic resection and ureteral reimplantation into the bladder vault].

Some prostatic cancers (T4) spread out along the ureters to the kidneys. Patients, usually arrive with terminal renal failure and bladder retention and have often fast-advancing cancer with massive nodes invading. T.

[Renal obstruction during pregnancy. Internal drainage using the JJ ureteral probe].

The advantage of using JJ ureteral stent during pregnancy in case of ureteral obstruction is shown two clinical observations. We use ultrasonography to control the site of this catheter during the operation and for the follow-up of the patients.
