BARVANA LONG: Symmcora® Long-term Bidirectional Barbed Suture for Anastomosis in Patients Undergoing Robot Assisted Radical Prostatectomy
Study Details
Study Description
Brief Summary
The aim of this observational study is to show the superiority of the bidirectional barbed suture (Symmcora® Longterm) in terms of time to perform the vesicourethral anastomosis after robot assisted radical prostatectomy compared to the available literature data, without an increase in the complication rate.

Outcome Measures
Primary Outcome Measures
- Time to perform the vesicourethral anastomosis [intraoperatively]
Time to perform the vesicourethral anastomosis using a stopwatch. Time starts when the needle passes the first time the tissue and ends after completion of the anastomosis. Completion of the anastomosis is defined by the last cut of the thread.
Secondary Outcome Measures
- Anastomotic leak rate until 6 months postoperatively [up to 6 months after surgery]
Cumulative number of anastomotic leaks
- Amount of estimate blood loss (EBL) [intraoperatively]
Blood loss is estimated by the amount of intraoperatively needed transfusion
- Transfusion rate [at discharge from hospital (approximately 5-10 days after surgery)]
Amount of transfused blood, Calculated by multiplication of the number of bags needed and the volume in ml per bag
- Urinary retention [at 6 weeks postoperatively]
Urinary retention is an inability to completely empty the bladder
- Urinary fistula rate [until 6 months postoperatively]
A urogenital fistula is an abnormal tract that exists between the urinary tract and bladder, ureters, or urethra. A urogenital fistula can occur between any of the organs and structures of the pelvic region. A fistula allows urine to continually exit through and out the urogenital tract.
- Bladder neck contracture rate [until 6 months postoperatively]
Cumulative rate of patients with a complication related to the bladder neck contracture
- Urinary stone formation rate [until 6 months postoperatively]
Cumulative rate of patients with a complication related to urinary stone formation
- Rate of other complications [until 6 months postoperatively]
Cumulative rate of patients with any other complication (infection, embolization, peritonitis, ileus, etc.)
- Operation consola time [intraoperatively]
Time to perform the intervention from first cut to last cut of the last thread. The time is measured using a stopwatch.
- Time to perform the Rocco stitch [intraoperatively]
Time to perform the modified Rocco stitch: After prostate extirpation, the free edge of the Denonvillier fascia is approximated to the posterior rhabdosphincter/median raphe using a running suture. Then, the Denonvilliers' fascia is fixated to the posterior wall of the bladder, which reduces tension in the anastomosis and provides pelvic support to the bladder neck. The time is measured using a stopwatch.
- Length of postoperative stay [until discharge (approximately 5-10 days postoperatively)]
Number of days from surgery till patient is discharged from hospital
- Catheterization duration [until first follow-up (6 weeks postoperatively)]
Number of days from surgery till catheter was finally removed
- Early continence [6 weeks postoperatively]
Days after catheter was finally removed to complete continence
- Development of continence by 24-h pad test [at 3 months and 6 months postoperatively.]
The 24-hour pad test is used as an objective diagnostic method for the assessment of post prostatectomy stress urinary incontinence. Pads are weighed before and after use and the amount of urine is measured.
- Development of Erectile Function compared to baseline [Preoperatively (Baseline), 6 weeks, 3 months and 6 months postoperatively.]
Erectile Function measured by International Index of Erectile Function (IIEF-5). The International Index of Erectile Function-5 (IIEF-5) is an five-item Index developed to diagnose the presence and severity of erectile dysfunction (ED). The five items are based on ability to identify the presence or absence of ED and on adherence to the National Institute of Health's definition of ED. These items focus on erectile function and intercourse satisfaction. The items are rated on a scale from 1-5 (e.g., 1=Very low to 5=Very high; 1=Almost never/never to 5=Almost always/always; 1=Extremely difficult to 5=Not difficult). The IIEF-5 score is the sum of questions 1 to 5 (Scores range from 5-25). ED was classified into five severity levels, ranging from none (22-25) through severe (5-7).
- Development of International prostate symptom score (IPSS) compared to baseline [Preoperatively (Baseline), 6 weeks, 3 months and 6 months postoperatively.]
The International prostate symptom score (IPSS) questionnaire has seven questions, which are used to evaluate storage and voiding symptoms. The patient is given five options for the first seven questions and each option indicates severity of that symptom. The total score ranges from 0 to 35 and Lower Urinary Tract Symptoms (LUTS) are classified as mild to severe depending on the total score. Patients having a total score ≤7 are classified as having mild symptoms, scores from 8 to 19 are classified as moderate symptoms, and symptom scores ≥20 are classified as severe symptoms.
- Comparison of Prostate Specific Antigen (PSA) at screening and 6 weeks after surgery. [at screening and 6 weeks after surgery.]
PSA response will be measured as the change of serum PSA in ng/mL between preoperative / screening examination and at follow-up 6 weeks after surgery
Other Outcome Measures
- Assessment of the intraoperative handling of the Symmcora® Long bidirectional [after inclusion of the last patient]
Handling of the suture is assessed for every participating surgeon once after inclusion of the last patient. Handling is measured in 16 dimensions + overall impression with five evaluation levels (excellent, very good, good, satisfied, poor)
- Assessment of the intraoperative handling of the Symmcora® Mid Unidirectional [after inclusion of the last patient]
Handling of the suture is assessed for every participating surgeon once after inclusion of the last patient. Handling is measured in 13 dimensions + overall impression with five evaluation levels (excellent, very good, good, satisfied, poor)
