“…Despite divergent observations by other authors, who found increased incrustations either with plain catgut [5,20,[22][23][24], with synthetic suture materials with PGS and polyglactin 910 [1,3,21,25] or with monofilic smooth, nonabsorbable polypropylene sutures [26][27][28], comparing these suture materials in the genitourinary tract, the present study -in concordance with others [5,6,29] only disclosed minor differences regarding incrustation due to various suture materials.…”

Five urinary bladder incisions were performed in 16 rabbits and the defects closed by plain catgut 4-0, chromic catgut 4-0, polypropylene 4-0, polyglactin 910 4-0 and polyglactin 910 8-0 in the form of an all-layer suture, thereby obtaining a total of 80 suture sites. The running sutures in 8 animals were reviewed by light microscopy after 1, 2, 7 and 15 weeks, and in 8 additional animals after 3 days, 1,2,7 and 15 weeks by scanning electron microscopy. Moreover, we analyzed and compared the autopsy findings on gross inspection, the urinary sediments and urinary cultures of the individual animals. Scanning electron-microscopic evaluations showed that epithelization of the intraluminal suture portions can be accomplished after 3 days already. Reduced suture strength and rapid absorption of the suture material prevent later postoperative incrustations. Light-microscopic inspection of the segments of the bladder wall bearing this suture material suggests that a minor inflammatory tissue response around the suture material – with polyglactin 910 8-0 in particular – is more likely to enhance regeneration of the tunica muscularis and to prevent formation of cysts than seen with a long-standing highly inflammatory tissue response around the suture site of catgut threads. In the animal experiment, the polyglactin 910 suture has shown sufficient firmness and proved to be superior to any other suture material as regards the reaction to foreign bodies and inclination to incrustation. A thinner thread used for sutures in the efferent urinary tract would thus have to be given preference over others. Plain catgut, chromic catgut and polyglactin 910 sutures, 4-0 in strength, were found to be disadvantageous in the animal model. The nonabsorbable propylene thread turned out to be inadequate in urinary bladder surgery.

“…Absorbable and nonabsorbable sutures used in the urinary tract have calculogenic potential. [27][28][29] In addition, a splinted uretero-ureterostomy with silastic catheters of appropriate caliber may result in specific complications such as upward gliding of the stent, clotting of the silicone tube, or possible perforation of the ureteric wall. 24 Also, the use of nylon tubes to ensure patency of the ureteral anastomosis may cause partial or total urinary tract obstruction, with uretero-pyeloectasia and consequent renal insufficiency.…”

Kidney transplantation procedures in rats: Assessments, complications, and management

Kidney transplantation in rats is an experimental model often used for the development of general microsurgical or transplantation techniques, for immunologic studies, and for analyzing transplant-associated long-term arterial blood-pressure changes. The aim of the present study was to analyze different surgical techniques of kidney transplantation in rats, with emphasis on minimizing surgical complications and establishing guidelines for their prevention and management. Complications were categorized into general (e.g., core body temperature drop, ischemic time) and surgically related vascular and urinary tract complications. In conclusion, a significant reduction of the complication rate in renal transplantation in rats can be achieved by placing the animal on a heating pad at an appropriate temperature. To reduce the risk of vascular thrombosis, ice-cold saline with heparin and careful flushing of the donor kidneys are recommended. Vascular complications can be avoided by performing "end-to-end" anastomosis techniques. The use of stents and cannulas in the urinary tract is associated with a high risk of urinary tract obstruction, and therefore is not recommended.

“…Studies on the lithogenic properties of various suture materials have shown that lithogenesis is proportional to the duration of absorption of the material. The highest incidence has been noted with nonabsorbable braided suture material; monofilament nonabsorbable sutures have similar problems, confirmed in experimental and clinical settings [ 2, 3, 8]. The use of both these types has been discontinued for bladder repair.…”

“…It is now accepted practice that only absorbable suture material should be used to repair bladder wall defects, although initial experimental evidence had suggested that polypropylene (a monofilament nonabsorbable suture) could be used in urological procedures [ 1–4]. Of the absorbable sutures, the earliest available and most frequently used until recently was chromic catgut.…”
