OBJECTIVETo evaluate the clinical results of the replacement of plaque by buccal mucosa in the treatment of Peyronie's disease.

METHODSWe performed surgical replacement of the plaque by free autograft of buccal mucosa on 27 patients with Peyronie's disease, ranging in age from 24 to 72 years (mean 53), varying in disease course between 1 and 13 years, with a penile curvature angle of 30 degrees - 80 degrees in erection. Of the total number, 15 patients had the plaque located in the dorsal root, 6 in the dorsal shaft, 3 in the subcoronal shaft and 3 in the ventral shaft of the penis; 24 had 1 plaque, 2 had 2 and 1 had 3, ranging in size from 0.7 cm x 0.7 cm to 1.6 cm x 1.0 cm.

RESULTSSatisfactory results were achieved in all the cases, with no such complications as hematoma, infection, oral numbness, and tightness of the mouth. Of the 24 cases that were followed up for 0.5 to 7 years, complete straightening of the penis was achieved in 21, slight residual curvature (< 15 degrees) was noted in 3, a little shortening of the penis (< 1 cm) in 2, and erectile pain in 3.

CONCLUSIONBuccal mucosa, with a stable elasticity and no shrinkage, can be recommended for wide use in the surgical treatment of Peyronie's disease.

AIMTo discuss important points on medical history, preoperative evaluation, real expectations, and selection of the appropriate surgical procedure to improve patient satisfaction after surgical procedures for Peyronie's disease.

METHODSRecent advances in approaches to Peyronie's disease are discussed based on the literature and personal experiences. Issues concerning surgical indication, patient selection, surgical techniques, and grafting are discussed. Lengthening procedures on the convex side of the penile curvature by means of grafting offer the best possible gain from a reconstruction standpoint. Penile rectification and rigidity are required to achieve a completely functional penis. Most patients experience associated erectile dysfunction (ED), and penile straightening alone may not be enough to restore complete function. Twenty-five patients were submitted to total penile reconstruction on length and girth with concomitant penile prosthesis implant. The maximum length restoration was possible and limited by the length of the dissected neurovascular bundle. The mean age was 55.4 years (32-69 years) and the mean angle of curvature 74.2+/-22.4 degree (0-100 degree). Pericardial grafting was used to cover the defect. The mean follow-up time was 11.2 +/- 5.9 months (3-22 months).

RESULTSMean functional penile length gain was 3.40+/-0.73 cm (2-5 cm). Penile prosthesis maintained the penis straight. No infections occurred. Sexual intercourse was restored in all patients and all reported recovered self-esteem.

CONCLUSIONImproving patient satisfaction with the surgical treatment includes proper preoperative evaluation on stable disease, penile shortening, vascular and erectile status, patient decision and selection as well as extensive discussion on surgical technique for restoring functional penis (length and rigidity). Length and girth restoration is very important for self-esteem and patient satisfaction.

PURPOSE: To evaluate the efficacy, safety and patient satisfaction outcomes following low intensity extracorporeal shock wave therapy (LiESWT) in men with Peyronie's disease (PD) using a standardised protocol. MATERIALS AND METHODS: In this open-label single arm prospective study, patients with PD were enrolled following informed consent. Patient demographics, change in penile curvature and plaque hardness, International Index of Erectile Function (IIEF)-5 score, and overall satisfaction score (on a 5-point scale) were recorded. Treatment template consists of 3000 shock waves to the Peyronie's plaque over 20 minutes, twice weekly for 6 weeks. RESULTS: The majority of patients have PD history longer than 6 months (mean, 12.8 months; range, 6-28 months). Two thirds of patients have received and failed oral medical therapy. There were improvements in penile curvature (more than 15 degrees in 33% of men), plaque hardness (60% of men) and penile pain (4 out of 6 men) following LiESWT. There was a moderate improvement in IIEF-5 score (>5 points reported in 20% of men). No complication was reported and the majority of patients were satisfied (rated 4 out of 5; 70% of men) and would recommend this therapy to others. CONCLUSIONS: In a carefully selected group of men with PD, LiESWT appears to be safe, has moderate efficacy and is associated with high patient satisfaction rate in the short term.

AIMTo evaluate the degree of corporal fibrosis in rats with cadaveric pericardium or vein as grafting materials for tunica albuginea substitution.

MATERIALS AND METHODSThirty male Sprague-Dawley rats (300 g approximately 325 g) were divided at random into 3 groups of 10 animals each: group 1 was the sham-operated controls and groups 2 and 3 underwent wedge excision of tunica albuginea and replacement with cadaveric pericardium and vein grafts, respectively. Four months later, rats were sacrificed and the penis removed to assess the degree of fibrosis using RT-PCR technique for TGF-bgr1 mRNA expression. The tissues were fixed in 10% formalin, paraffin-embedded and stained with Masson's trichrome and Verhoff's van Giesen for collagen and elastic fibers.

RESULTSFour months after grafting, there was minimal fibrosis surrounding the patch in the vein graft rats and moderate fibrosis in the pericardial graft rats. The degree of penile fibrosis in the pericardial graft rats was significantly higher than that in the controls (P<0.01), but in the vein graft rats it was not significantly different from that of the controls (P>0.05).

CONCLUSIONThe degree of penile fibrosis of cadaveric pericardial graft was significantly higher than that of the control group, while in the vein graft group it was comparable to the latter. The authors believe that the vein graft may be a more ideal substance to be used as the tunica albuginea substitute than the pericardial graft in the surgical treatment of Peyronie'S disease.
