Clinical comments on management of urosepsis in a general urological department.

Over a period of 6 years 192 cases of urosepsis have been recorded and managed in our urological department. In almost all cases (97%) the primary focus of infection was the urinary tract and the responsible microorganisms were Gram-negative rods, in order Enterobacter, B. Proteus, E. Coli, Klebsiella and others. Clinical features were dominated by symptoms related to failure or insufficiency of end organs (fever, hypotension, oliguria, mental disorders, respiratory distress etc.). Bacteremia was diagnosed with an incidence of 66%, septic shock 12% and MSOF 20%. Negative bacteriological tests do not rule out the diagnosis of systemic infection. Risk factors are considered advanced age, uremia, diabetes, malnutrition and extensive surgery.

Renal carcinoma with inferior vena cava malignant thrombosis.

During an 11-year period a total of 314 patients underwent surgery for renal carcinoma; 70 had venous extension of the tumour, 31 had extension to the main renal vein and were staged V1 and 39 had involvement of the inferior vena cava and were staged V2. Special attention was paid to the latter group, which was divided into 2 subgroups: V2a for caval extension without ingrowth and V2b for caval extension with infiltration of the caval wall. Thirty-eight patients with caval involvement underwent surgery, with a 13% post-operative mortality rate. Most of the patients with malignant caval ingrowth (V2b) had concomitant lymph node and distant metastases. However, some had negative lymph nodes and no metastases at the time of operation. Perifascial nephrectomy associated with caval tumour removal or lateral subhepatic caval resection for patients staged V2aNOMO significantly increased the survival rate when compared with that of patients with no surgery on the obstructed vena cava. Total resection of the completely obstructed subhepatic vena cava for patients staged V2bNOMO has limited indications but, in selected cases, may prolong survival. This retrospective study supports the reintroduction of indicator V in the TNM staging of renal carcinoma and suggests the splitting of stage V2 into V2a for patients with free-floating caval extension and V2b for caval thrombus with ingrowth and caval wall infiltration.

[Cervicoprostatic section, an endoscopic alternative in treating periurethral adenoma].

Uni- and bilateral endoscopic sectioning of the vesical collum and of the prostatic tissue has become an efficient therapeutic alternative for small and middle adenomas and cervicoprostatic scleroses. The authors recommend the use of bilateral cervicoprostatic endoscopic sectioning, with resection of the intermediary tissue (that adds important advantages), harvesting of prostatic tissue for anatomopathologic examination and removal of the remaining tissular isle that might later obstruct the urethra. This original therapeutic method was used in 38 cases (added to 25 patients treated only by uni- or bilateral cervico prostatic section). The good results obtained, without important complications, lasted in time on the dysectatic syndrome, in the patients with cervicoprostatic sclerosis and small and middle adenomas.

A new transperitoneal approach for retroperitoneal lymphadenectomy.

A new transperitoneal approach for retroperitoneal lymphadenectomy is presented. The abdominal incision resembles the letter omega, gives free access to both suprahilar renal areas and abdominal pelvis and provides solid repair of the abdominal wall. It may also be used for surgery on both kidneys and adrenals.

Cavernosography in the management of prostatic cancer.

Cavernosograms were used in the investigation of 22 patients with prostatic cancer to determine the incidence of venous invasion. There were 21 patients with T3/T4 category tumours and one with a T2 tumour. All but one, a T3 tumour, had the radiological features of periprostatic venous malignant thrombosis. An attempt was made to correlate these findings with lymphography and tumour grade but no correlations could be made and the clinical relevance of these findings remains uncertain.

An undeservedly neglected prostatectomy: Fabre's technique.

Fabre's prostatectomy technique was applied to 100 consecutive unselected patients with no mortality and minor complications. Three technical failures were recorded. No urethral catheter was used, the bladder being drained through a lateral hypogastric stabwound. The incidence of urinary infection was greatly reduced in this series.
