ENDOLUMINAL-ULTRASOUND IN DIAGNOSIS THE FUNCTION OF THE MALE RHABDOSPHINCTER IN PATIENTS UNDERGOING RADICAL PROSTATECTOMY Gernot Helweg, Ferdinand Frauscher. Hannes Strasser,
Objectives: To compare the value (IUUS) in incontinent female with
of intraurethral ultrasound urodynamic studies.
Methods: 31 patients (age 24-76 years) with incontinence were examined by means of IUUS. 19/31 had stress-, 6/31 urge- and 6/31 combined stress-urge-incontinence. The operating frequency of the flexible ultrasound catheters (9-F) was 12.5 MHz. All consecutive urodynamic studies were obtained by a Dantec UD 5500 System. Results: The IUUS examination showed a muscle thickness of 0.31cm (kO.06) in stress incontinence grade I and 0.29cm (iO.05) in grade II and 0.18cm (+0.06) in grade Ill, A contaction of the sphincter muscle was revealed in grade I and II, grade Ill demonstrated no contractility. In case of urge incontinence a muscle thickness of 0.33cm (_+0.07) was found with good sphincter contractility. Urethral closure pressures were decreased in all patients. Conclusions: incontinence visualization new aspects
IUUS is a helpful tool in the diagnosis of stress and correlated well with urodynamic studies. Direct of the rhabdosphincter and its contractility may offer for therapy.

the function of the male rhabdosphincter in cases of prostatic cancer.
Methods: 81 patients suffering from prostatic cancer were studied before radical prostatectomy. 43/81 patients within month after radical prostatectomy. Ultrasound examinations performed by transurethral sonography (IVUS. 12.5 MHz transducer. 9-F catheter). All patients were correlated by urodynamic studies.

Results:ln the 43 postoperative follow-up studies a mean increase in muscle thickness of 0.8 +O.O3mm was detected. The urodynamic studies showed a decrease of the functional length of 3.07cm. 39/43 patients were continent within 3 month ar .!r radical prostatectomy. Conclusions: Even though radical prostatectomy causes a decrease of the functional length of the urethra, increased muscle thickness achieved by postoperative training, could be revealed by endoluminal ultrasound, indicating continence. Endoluminal ultrasound proved to be an exellent tool to estimate the functional capabilities to the rhabdosphincter.

THREE-DIMENSIONAL RECONSTRUCTIONS OF ENDOLUMINAL UROLOGICAL FINDINGS W. Recheis, Ft. Eder, F. Frauscher, K. Colliselli, G. Helweg, A. Klauser, D. zur Nedden Department of Radiology II and Urology, University of Innsbruck, Austria Objectives: To calculate threedimensional reconstructions for preoperativ planning. Methods: 3 patients with urethral diverticula were investigated. An intraurethral ultrasound unit (IVUS, Diasonics) with 9-F flexible ultrasound catheters was used as the image source. The x and y dimensions were scaled to a standard grid of the ultrasound unit. To get the information of a z-axis the ultrasound head was mounted on a mechanically driven puller. The puller was moved lmmlsec. The images were tranferred to an external workstation via a frame grabber. The segmentation process was done using semiautomatic algorithms. The threedimensional reconstruction were calculated using commercially available software packages. Results: All diverticula could be well reconstructed. The anatomical location of the diverticula relative to the external sphincter of the urethra could be determined clearly. Especially the ductus of the diverticulum was visualized. Conclusions: This technique seems to be very helpful in preoperative planning in different fields of urological surgery and was superior to axial ultrasound scans.

Objective: Establishing of ultrasound characteristics and evalution of possibility of urinary bladder wall infiltration degree. Material and methods: A group of 69 patients (18 women and 51 men) have been examined by transabdominal real-time ultrasound. Urinary bladder tumours have been diagnosed in all patients. Ultrasound findings have been compared with computed tomography (CT), intraoperative, and pathohistological findings. Results: Based on the ultrasound characteristics. urinary bladder tumours have been classified as: proliferative (46.7%). infiltrative (14.4%) and mixed form (38.9%). US reliability in determining of urinary bladder tumour and its infiltration degree into the perivesical space has been established at 73%. Conclusion: US represents a significant diagnostic procedure in finding and determining of tumour morphology, as well as the evaluation of urinary bladder wall infiltration.
