A new corporoplasty based on stratified structure of tunica albuginea for the treatment of congenital penile curvature - long-term results.

ABSTRACT: INTRODUCTION: The aim of the study was to report long-term results of treatment of patients with congenital penile curvature (CPC) with a new corporoplasty based on stratified structure of tunica albuginea, in which corporal bodies are not opened. MATERIAL AND METHODS: From October 2006 to September 2013, the authors operated on 111 adult men with CPC. Ventral curvature was detected in 65 patients, lateral in 34, and dorsal in 12. Skin was incised longitudinally on convex surface of curvature. In ventral curvature, dorsal neuro-vascular bundles (NVBs) were separated from tunica albuginea and elliptical fragments of external (longitudinal) layer of tunica were excised. The tunica was sutured with absorbable sutures, which invaginated the internal (transversal) layer of tunica. In dorsal curvature, excisions were performed on both sides of the urethra, in lateral curvature - on the convex penile surface. RESULTS: Follow-up period was from 12 to 84 months. The penis was completely straight in 109 out of 111 patients. In 2 patients (1.8%) recurrent curvature of up to 20 degrees was detected. Redo surgery was done in one individual (0.9%) at patient's request. Glandular sensation loss or erectile dysfunction was not detected in any patient during the period of observation. CONCLUSIONS: A new operation for correction of CPC, which consists of excision of an elliptical fragment of the external layer of the tunica albuginea and plication of the internal layer gives good short and long-term results. Surgery done without penetrating the corpora cavernosa is minimally invasive, which diminishes the potential risk of complications, especially intra- and postoperative bleeding.

Project description:The aim of the study was to report methods - based on penile anatomy - leading to the minimization in the invasiveness of reconstructive surgery for congenital penile curvature (CPC).From 2006 to 2016 authors operated on 186 adult men with CPC.To avoid degloving, the authors used the longitudinal skin and tunica dartos incision. For decreasing invasiveness to the dorsal neurovascular bundle (NVB), the authors separated it only locally in the shape of a triangle or a trapezium, elevating it only over the place of the tunical reconstruction. To decrease the invasiveness for the tunica albuginea (TA) and cavernous vessels, a new operative technique based on the stratified structure of the TA was developed in which the corpora cavernosa were not opened. During reconstruction, only the elliptical fragment of the external layer of the tunica was excised (internal layer was left intact) and both layers of the tunica were sutured over the invaginated internal layer.Follow-up ranged from 6 months to 10 years. In all the patients, the penis was straightened during operation. Follow-up examinations were done 6 months and 1 year postoperatively. Disorders of superficial sensation on the glans, erectile dysfunction or chronic postoperative edema were not detected in any of the 186 patients. The penis remained straight in 180 patients (96.7%). In 4 patients (2.2%) in whom the primary curvature was 80-90 degrees and the postoperative curvature was about 30 degrees, reoperation was done. In two patients (1.1%) with the remaining postoperative curvature up to 20 degrees and good functional result (patient's opinion), there was no need for further treatment.Longitudinal skin and tunica dartos incision on the convex surface of the penis allows for the ability to avoid penile degloving and to preserve the foreskin. Elevation of the dorsal NVB from the TA was done on a very limited surface in the shape of triangle or trapezium, in order to decrease the possibility of dorsal nerves/vessels damage. Excision of elliptical fragments of the external layer of the TA with subsequent invagination of the internal layer, excluded the need for opening of the corpora cavernosa as well as for the use of a tourniquet during reconstruction. This diminished the potential risk of complications, especially intra- and postoperative bleeding.

Project description:BackgroundNumerous surgical techniques are available for the correction of isolated ventral congenital penile curvature (IVCPC). This study aimed to assess the outcomes and predictors of IVCPC treatment in adults using an incisionless plication technique.Materials and methodsThis prospective case series examined patients with IVCPC who were treated in our hospital between October 2017 and February 2020 using incisionless plication of the tunica albuginea (Essed-Schroeder technique) with a covering pair of absorbable sutures. The primary outcomes were successful correction (defined as a residual curvature ≤15 degrees) and patient satisfaction. Postoperative follow-ups were performed at 3, 6, and 12 months.ResultsA total of 23 patients were treated for IVCPC with a mean (range) age of 25.3 (18-31) years. Eighteen patients (78.3%) were single with cosmetic complaints, whereas the other 5 patients (21.7%) were married and presented with a difficult vaginal intromission. The mean (range) curvature, length, and operative time were 40 (30-50) degrees, 15 (10-19) cm, and 82 (65-100) minutes, respectively. Postoperative penile pain and numbness occurred in 13 patients (56.5 %) and 7 patients (30.4%) only within the first month, respectively. Palpable suture knots were reported in 15 patients (65.5%) without being bothersome up to 12 months. The postoperative means (ranges) of penile curvature and length were significantly different from that of the preoperative values at 3 (5 [0-20] degrees and 14.5 [9-18.5] cm), 6 (5 [0-20] degrees and 14.5 [9-18.5] cm), and 12 months (5 [0-30] degrees and 14.5 [9-18.5] cm; all p < 0.001). Age, preoperative penile curvature, penile length, postoperative pain, wound infections, and knot palpation insignificantly affected curvature recurrence. Seventeen patients (73.9%) were very satisfied with their surgical outcomes.ConclusionsIncisionless plication of the tunica albuginea is effective and safe for the correction of IVCPC in adults with high success and patient satisfaction rates.

Project description:Melanoma treatment has been revolutionized over the past decade. Long-term results with immuno-oncology (I-O) agents and targeted therapies are providing evidence of durable survival for a substantial number of patients. These results have prompted consideration of how best to define long-term benefit and cure. Now more than ever, oncologists should be aware of the long-term outcomes demonstrated with these newer agents and their relevance to treatment decision-making. As the first tumor type for which I-O agents were approved, melanoma has served as a model for other diseases. Accordingly, discussions regarding the value and impact of long-term survival data in patients with melanoma may be relevant in the future to other tumor types. Current findings indicate that, depending on the treatment, over 50% of patients with melanoma may gain durable survival benefit. The best survival outcomes are generally observed in patients with favorable prognostic factors, particularly normal baseline lactate dehydrogenase and/or a low volume of disease. Survival curves from melanoma clinical studies show a plateau at 3 to 4 years, suggesting that patients who are alive at the 3-year landmark (especially in cases in which treatment had been stopped) will likely experience prolonged cancer remission. Quality-of-life and mixture-cure modeling data, as well as metrics such as treatment-free survival, are helping to define the value of this long-term survival. In this review, we describe the current treatment landscape for melanoma and discuss the long-term survival data with immunotherapies and targeted therapies, discussing how to best evaluate the value of long-term survival. We propose that some patients might be considered functionally cured if they have responded to treatment and remained treatment-free for at least 2 years without disease progression. Finally, we consider that, while there have been major advances in the treatment of melanoma in the past decade, there remains a need to improve outcomes for the patients with melanoma who do not experience durable survival.
