“…The detection of cytoskeletal intermediate filament protein vimentin, which is normally expressed in mesenchymal cells, along with lack of desmin and α-SMA in most cells, could prove the presence of fibroblasts in the developing connective tissue, which are needed for sustainable healing. The results of current study is partly similar to of Hodjati et al (2013), which showed the readiness of the renal capsule for being a platform for growth and proliferation of epithelial tissue [19]. Although it is not evolved to resist osmotic alterations of urine, the renal capsule flap in conjunction with a DJ stent…”

“…The proximal third of the ureter is more prone to injury than its middle and distal third [1]. Renal capsule has been previously used in repair and or reconstruction of the Achilles tendon [18] and inferior vena cava [19]. To our knowledge, the first documented attempt of employing the renal capsular flap was done by Thompson et al which dates back to 1963.…”

sis, urinoma [5] and kidney loss [6]. The repair of the damaged ureter through inosculating of the interrupted ends of the tube is sometimes not feasible, needing additional efforts to fix the lesion. Based on the type of injury, different restoration techniques such as appendiceal substitution of the ureter [7], Boari bladder flap [8], ureteroenterostomy [9], transureteroureterostomy [5], psoas bladder hitch [10], ureteroneocystostomy [11], buccal mucosa graft [12], abdominal wall muscle flaps [3] and reinforced collagen scaffolds [13] have been developed over the years. Herein, we report a practicable technique aimed at the reconstruction of the damaged proximal ureter using an autologous flap of the renal capsule.

“…One can easily use the renal capsule for AC in patients with non-functional native kidneys without the fear of damaging the renal parenchyma. Although Hodjati et al ( 20 ) showed no renal parenchymal damage after removing the capsule in canine models, and we also did not find any gross abnormality of the decapsulized kidneys during second exploration, there is still concern for its applicability in humans with normally functioning kidneys.…”

“…Thompson et al reported their clinical experience of flap pyeloplasty using renal capsule and their results were acceptable ( 19 ). Hodjati et al ( 20 ) applied the canine renal capsule as a venous patch graft for inferior vena cava repair and their entire specimens remained patent with endothelial regeneration over the surface of renal capsule 3 months after the operation. To the author's knowledge our study is the first experience of AC using renal capsule, which we introduce as capsule-cystoplasty.…”

Purpose:To evaluate effectiveness of canine renal capsule for augmentation cystoplasty.Materials and Methods:Ten adult dogs participated in this study. After induction of anesthesia each animal underwent bed side urodynamic study, bladder capacity and bladder pressure was recorded. Then via mid line incision abdominal cavity was entered, right kidney was identified and its capsule was dissected. Bladder augmentation was done by anastomosing the renal capsule to the bladder. After 6 months bed side urodynamic study was performed again and changes in bladder volume and pressure were recorded. Then the animals were sacrificed and the augmented bladders were sent for histopathology evaluation.Results:Mean maximum anatomic bladder capacity before cystoplasty was 334.00±11.40cc which increased to 488.00±14.83cc post-operatively (p=0.039). Mean anatomic bladder pressure before cystoplasty was 19.00±1.58cmH2O which decreased to 12.60±1.14cmH2O post-operatively (p=0.039). Histopathology evaluation revealed epithelialization of the renal capsule with urothelium without evidence of fibrosis, collagen deposits or contracture.Conclusions:Our data shows that renal capsule is a favorable biomaterial for bladder augmentation in a canine model.
