“…In the BNP and DULP group V-Loc™ was used in most cases, while in the group without BNP and DULP Van Velthoven sutures were was used in more than 30% of patients. The Van Velthoven suture was shown to be more time-consuming [16]. The other possible explanation for the longer anastomotic time in the group without BNP and DULP is the larger diameter of BN and more needle-passes needed for VUA.…”

Introduction: Radical prostatectomy (RP) is the standard surgical treatment for localized prostate cancer (PCa), with excellent oncologic outcomes; however, complications such as post-prostatectomy incontinence could significantly affect quality of life. Aim: To provide data on long-term urinary functional outcomes of bladder neck preservation (BNP) combined with distal urethral length preservation (DULP) in patients treated with videolaparoscopic prostatectomy. Material and methods: In this retrospective study, data were analysed from 619 consecutive patients who underwent laparoscopic radical prostatectomy (LRP) due to localized prostate cancer between November 2014 and December 2018 in a single tertiary care centre in Poland. Of these patients, 227 had BNP and DULP during the procedure. Urinary continence status was assessed in patients at 3, 6, 12, and 18 months after LRP. Cancer resection was assessed by surgical margin status. Results: In the group with BNP and DULP, urinary continence recurred earlier than it did in the control group up to 3 months after surgery: 204 (89.8%) patients in this group were fully continent compared with 283 (72.2%) in the control group (p < 0.001). The difference was also significant after 6 months (95.1% vs. 80.6%, respectively; p < 0.001). Despite these early promising results, there was no difference in urinary continence recovery after 12 and 18 months. There was also no difference between the 2 groups regarding surgical margin status of the resected tissue. Conclusions: Our study showed that BNP combined with DULP is a safe procedure that helps to improve early urinary continence rates after surgery without altering the risk of positive surgical margin.

“…The diameter of the distal urethra and bladder neck were mostly similar. The tension-free VUA was performed by using 3 different types of sutures [16]. After both ends of the suture were tied, the watertightness of the anastomosis was assessed by filling the bladder with 100-200 ml of sterile physiological saline.…”

“…The number of stitches placed with 2D and 3D cameras was not different. It is difficult to achieve a water-tight anastomosis in human patients since a urinary catheter and an abdominal drain are maintained from several days to weeks to limit the risk of uroabdomen while waiting for the VUA to seal [10,[25][26][27][28][29][30][31]. Special clips are commonly used in human patients to maintain tension on the continuous line of suture and provide a better seal [11,24,32].…”

Objective To describe the technique of laparoscopic radical prostatectomy in canine cadavers. Study design Cadaveric study. Animals 8 canine cadavers. Methods Specimens were randomly divided into a 2D or 3D group. The vesicourethral anastomosis (VUA) was performed with 5 mm laparoscopic needle holders. A unidirectional barbed suture was used to complete the VUA with two simple continuous suture patterns. The number of stitches placed, the patency of the anastomosis, and the distance between the VUA and the ureters were recorded. Results Four dogs were entered into each group. The prostatectomy was completed in each dog following the same technique. VUA were completed with nine stitches (range: 8–10 stitches) for the 2D group and ten stitches (range: 9–11 stitches) for the 3D group (p<0.176). All the stitches were placed full thickness. The VUA was patent in each case. The left ureter was 1.05 cm (range: 0.5 to 1.1cm) from the VUA in the 2D group and 1.8 cm (range: 1.3–1.8 cm) for the 3D group (p< 0.025). The right ureter was 1.5 cm (range: 1 to 2 cm) from the VUA in the 2D group and 1.75 cm (range: 1.3–2 cm) for the 3D group (p< 0.55). Conclusion Laparoscopic radical prostatectomy can be performed with a 2D or a 3D camera in canine cadavers. The 3D camera results in more accurate placement of the sutures since they were placed further away from the left ureter. Clinical significance Radical prostatectomy with laparoscopy should be considered for dogs.

Objective: To compare leakage pressures of vesicourethral anastomosis (VUA) performed with conventional and unidirectional barbed sutures in canine cadaveric tissue.Study design: Experimental, ex-vivo, randomized study.Animals: A total of 24 male canine bladders with the urethra. Methods: Specimens after prostatectomy were randomly divided into a unidirectional barbed suture (UBS) or a conventional suture (C) group. For the UBS group, the VUA was performed with 4-0 unidirectional barbed sutures. For the C group, the VUA was performed with 4-0 monofilament absorbable suture. The VUA was completed with two simple continuous sutures. Surgical time, leakage pressure, site of leakage, and the number of suture bites were recorded. Results: The median suturing time was 12.70 minutes (range: 7.50-16.10 min) for the UBS group and 17.30 minutes (range: 14.00-21.30 min) for the C group (p < .0002). The median leakage pressure was 8.60 mmHg (range: 5.00-17.20 mmHg) for the UBS group and 11.70 mmHg (range: 6.00-18.50 mmHg) for the C group (p = .236). The median number of suture bites was 14 (range:11-27) for the UBS group and 19 (range:17-28) for the C group (p = .012). Conclusion:Unidirectional barbed suture does not statistically affect the acute leakage pressure of VUA in normal cadaveric specimen. It resulted in a shorter surgical time and fewer suture bite placements. Clinical significance: A urinary catheter will still be required when a unidirectional barbed suture is used to complete a VUA in dogs to prevent extravasation of urine in the postoperative period.
