Bladder outflow after radical prostatectomy.

Postoperative bladder outflow was assessed in 150 patients subjected to radical retropubic prostatectomy for clinically localized prostate cancer. The overall mean (+/- S.E.M.) postoperative peak flow rates and residual urine volumes were 16.9 +/- 1.3 ml/s and 11.4 +/- 2.1 ml. According to flow nomograms, 22% of the patients were still obstructed postoperatively due to stricture of either the anastomosis or the urethra (12%), or to partial bladder denervation (10%). Scoring of subjective symptoms was not reliable in detecting postoperative outflow obstruction, while uroflowmetry with flow nomograms identified all obstructed cases. Radical retropubic prostatectomy can induce both mechanical and functional alterations of the distal urinary tract and a strict assessment of postoperative bladder outflow is recommended.

[Use of ultrasonography in morphofunctional evaluation of orthotopic neo-bladder].

Seventeen patients submitted to radical cystectomy and orthotopic bladder replacement according to Reddy's technique were studied at the 1, 3, 6 and 12-month, then annually follow-up by physical examination, intravenous pyelogram, cystourethrography, suprapubic and transrectal ultrasonography and complete urodynamics. Sixteen patients (94%) reported day-time urinary continence and twelve patients (70%) day-time and nocturnal continence. Cysto-manometry showed a mean bladder capacity of 450 cc with a maximal endocavitary pressure of 40 cm. H2O and satisfactory peak flow rate. Vesico-ureteral reflux was never detected at roentgenography. Ultrasonography may be useful in the study of a possible reflux or stenosis of the neovesico-ureteral junction by detecting renal scars or dilatation of the renal cavities. Sovrapubic ultrasonography can quantify the capacity of the neo-bladder (300-600 cc), study its shape, walls and contractions that do not cause the involuntary opening of the neo-bladder neck. Transrectal ultrasonography studies the bladder neck shape and its dynamic function. Residual urine volume never exceeded 50 cc. Ultrasonography demonstrated its effectiveness and reliability and limited the application of more invasive roentgenographic procedures.

[Conservative elective surgery in kidney neoplasms].

After the good results of "necessary" conservative surgery in the treatment of kidney neoplasms (bilateral neoplasms, congenital, acquired or functional solitary kidney), conservative surgery itself has been employed as elective treatment in selected cases presenting without the overmentioned problems. The authors report two cases of elective conservative surgery in kidney neoplasm with good results after 18 and 24 months.

[Preliminary clinico-urodynamic study of diabetic uropathy of the bladder].

Twenty-eight diabetic patients of type one have been evaluated in a preliminary study starting from the conclusions of a previous work of the Authors, where the existence of four types of autonomic bladder neuropathies was demonstrated, in opposition to the classic theory of diabetic cistopathy. The examined cases confirm on the basis of clinical trials (HBA1C, cardiovascular autonomic neuropathy tests) and urodynamic tests (urofluxometric test, cistomanometric test, urethral pressure profile) the pleiomorphism of this syndrome and its relations with diabetic disease. On the total amount of the examined cases, 16 patients (57%) showed high values of HBA1C and 17 (60.7%) positive tests for autonomic neuropathy. Distribution of different types of cistopathy confirmed furthermore, beside the higher incidence of the sensitive form (14 pts.), an important percentage of sensitive motory types (4 pts.) and hyperreflexic ones (3 pts.). On the basis of the reported data, a correct and precocious differential diagnostics is recommended in order to face in a better way the serious consequences which may tardily affect the urinary apparatus.

[Anatomical and surgical considerations on the internal spermatic venous system].

The surgical anatomy of the spermatic venous system is described. Thereafter an experimental evaluation performed on cadavers by the vascular mould technique using plastic materials is reported. The resulting data point out the complex variability of the spermatic venous circulation, stressing the value of preoperative phlebography in the surgical approach to varicocele.
