“…Seven patients required reduced diameter devices (AMS 700 CXM™), while two received standard sizes (AMS 700 CX™). Mean length of excised fibrotic corporal segments was 5.2 cm (range 4-7), and mean PP cylinder length was 13.8 cm (range [12][13][14][15][16]. No patient required grafting, and all patients reported limited thrusting with intercourse, presumably due to inadequate functional penile length.…”

Introduction Penile corporal fibrosis represents a challenging clinical scenario for surgeons placing penile prostheses (PP). Because of its rarity, a small number of series with limited follow-up have reported outcomes in this cohort. Aim The aim of this study was to perform a critical appraisal of the corporal excavation technique, discuss its relevance to contemporary practice, and review alternative surgical methods and outcomes. Methods A critical review was performed of the 2006 article by Montague and Angermeier, “Corporeal excavation: new technique for penile prosthesis implantation in men with severe corporeal fibrosis.” Notable inclusions and omissions were described, with emphasis placed on methodology and outcomes. A PubMed search from 1990 to June 2015 was then performed to review and summarize the literature on managing corporal fibrosis during PP surgery. Main Outcome Measures The main outcome measures used were the major contributions and limitations of the 2006 article describing outcomes of the corporal excavation technique. Results Corporal excavation is a relevant surgical technique for managing severe corporal fibrosis. Compared with alternatives, excavation achieves successful placement of PP without need for grafting and with few complications. The article was limited by several notable omissions including relevant patient demographic and disease characteristics, patient selection, and minimal descriptions of complications and outcomes. Alternative techniques include use of specialized dilators, counter incisions, reconstruction with graft placement, minimal scar tissue excision, and endoscopic resection. Because of limited data, no specific algorithm for managing corporal fibrosis can be prescribed. Conclusions Corporal fibrosis is a challenging clinical scenario and requires surgical experience and specialized techniques to manage appropriately. Corporal excavation represents one of several viable techniques, which may be chosen based on surgeon’s preference and clinical factors.

“…Since the outcome of interest in this review was the result of pericardial grafts in reconstructive urologic surgeries, we also entered case reports in our review. Seven hundred fifteen patients underwent surgical reconstruction using pericardial grafts and had completed follow-up evaluations; 8 of these patients were published as case reports [8,10,11,31,37,40,47,48]. In addition, urologic reconstructive surgeries using pericardial grafts were performed on 139 animals comprising 45 rats [27,[54][55][56], 57 dogs [52,53,57,58], 31 rabbits [24,25,51], and 6 pigs [23].…”

“…Of those, there were 16 studies on patients with Peyronie's disease and/or penile straightening [9, 26, 30, 32-36, 39, 43-47, 49, 50], 3 reports on penile prosthesis complications [10,38,41], and 1 case of congenital chordee of the penis [40]. There were 2 reports of urethral reconstruction with successful outcomes and no complications [37,42].…”

“…Four hundred fifty-six patients underwent penile reconstruction with BP grafts [32-34, 38, 39, 43, 45, 50]; approximately 91% (range 75-100%) of those patients were satisfied with the outcomes of surgery at last follow-up, and the mean of the success rate was approximately 98.6% (range 93.3-100%). There was a single case of penile reconstruction with a BP graft, during which the BP was used as a lining for a complicated penile prosthesis [10]. There were 2 failed procedures after penile reconstruction, consisting of the repair of congenital chordee [40], the development of an inclusion cyst, and the contraction of the HCP graft in Peyronie's disease [47].…”

“…The pericardium tissue, either human or animal type, is composed of collagen, elastin fibers, and extracellular matrix [60]. Not only is BP inexpensive, but also it possesses such features as elasticity, lack of transmission of diseases, low rate of retraction, and good tension tolerance [10]. After treatment in glutaraldehyde, BP turns into a strong, easy-to-handle, durable, and low antigenic graft.…”

Introduction: The use of pericardium has been expanded into different surgical modalities; however, there are scarce data regarding the feasibility of the pericardium in reconstructive urologic surgeries. We systematically reviewed the literature on the effectiveness of the pericardial tissue for reconstructive urologic surgeries. Materials and Methods: PubMed and Scopus were searched online for evidence on the use of the pericardium in urologic surgeries. Through the methodology recommended by the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, 38 of 4,071 studies were identified. Results: A total of 715 patients and 139 animals underwent reconstructive urologic surgeries using the pericardium. Bladder, urethral, and renal reconstructions were successful in 100% of the human cases. The rates of dissatisfaction, glans hypoesthesia, and penile shortening were comparable between the pericardial graft surgeries and the other operations during penile straightening, but there was a trend among the patients with pericardial grafts toward having a more penile curvature at follow-up (risk ratio [RR] 2.03, 95% CI 0.90–4.61, p = 0.09; I² = 0%). Among the animal studies, there were 4 reports of penile reconstruction, 7 studies of bladder reconstruction, and 1 study of urethroplasty. Bladder reconstruction and urethroplasty were successful in 83 and 20% of the animals, respectively. The pooled result of the stimulated intracorporeal pressure 5 V significantly favored pericardial grafts during penile reconstruction (RR 2.61, 95% CI 1.26–3.97, p = 0.0002; I² = 0%). Conclusions: Our systematic review demonstrates the feasibility of the pericardium, regardless of its type, in urologic surgeries. It, however, seems that urethral substitution needs further investigation. Given the lower cost, easier handling, and less immunogenicity of the pericardium, further studies are required to examine its pros and cons.
