<em>Introduction</em>: Hypospadias is one of the most common birth defects that affect the male urogenital tract. It can present as isolated anomaly, but sometimes can arise in the context of complex disorders of sex development (DSD). These malformations are characterized by a great variety of clinical manifestations and compromise the aesthetic appearance, but also functional and psychological impact that the malformation can determine the patient. <br /><em>Materials and Methods</em>: We conducted a retrospective study of patients undergoing surgery for hypospadias from March 2000 to January 2015. The data was extrapolated from a prospective database. It was considered for each patient: demographics; type of hypospadias; surgical technique; average age for surgery; intraoperative and postoperative complications (early and late). Duckett’s classification was used. <br /><em>Results</em>: 343 urethroplasties were performed. 320 (93%) were primary urethroplasties and 23 (7%) reoperations in patients who had performed many other surgical procedures. 7 patients with megameatus were excluded. The hypospadias have been ranked according to Duckett’s classification, 35 patients had associated diseases. In total were performed: 186 (55%) Snodgrass, 71(21%) Duckett,10 (3%) augmented Duckett, 42 (13%) Magpi, 16 (5%) Duplay, 1 (0,3%) Bracka, 1 (0,3%) was a Bianchi’technique and 5 (1,4%) were Standoli. In 4 patients (1%) were used mixed technique. There were no intraoperative complications. The mean age at surgery was 15 months (range 12-22 months). Postoperative complications were 12%. Long term follow up was done with uroflussimetrie at 3 and 6 months in those who had reached the continence and possible urethral calibrations in those who had submitted a stenosis in post-op.<br /><em>Conclusions</em>: The improvement of surgical techniques, the use of optical amplification tools, the use of suture material (PDS) and the experience gained in recent years have enabled us to optimized the results. Though aware of the potential and actual complications that this type of microsurgical correction can lead to the results we have obtained are comparable to those of major international series and can be considered satisfactory, both from an aesthetic and functional.

Abstract Background Excimer laser trabeculotomy (ELT) is a minimally invasive procedure to lower the intraocular pressure (IOP) via a photo-ablative laser that is applied to the trabecular meshwork. With this procedure, it is possible to improve the outflow of the aqueous humor. Until now, a limited number of studies examining mostly relatively small sample sizes with midterm follow-up exist. We therefore present the analysis of a large ELT cohort in a long-term follow-up. Methods We recorded data from 580 patients who underwent ELT or combined ELT with cataract surgery at our institution from November 2000 until March 2011. A total of 512 patients with primary open angle glaucoma (POAG), pseudoexfoliation glaucoma (PEX), and ocular hypertension (OHT) were included in the analysis. At every follow-up examination, the usage of IOP-lowering medication and the IOP were recorded. Failure criteria were defined as the need for another surgical glaucoma procedure, when the IOP was not 21 mmHg or less and a reduction of 20% from the baseline was not achieved with (qualified success) or without (absolute success) additional medication. Statistical analysis was done using Kaplan-Meier analysis and Cox regression. Results Four hundred twenty-eight patients underwent combined cataract and ELT surgery, and 84 underwent solitary ELT surgery. After a median follow-up time of 656 days, 87% (combined surgery) and 66% (ELT) of the patients did not have to undergo another IOP-lowering intervention; 47/31% were classified as a qualified success and 31/11% as a complete success. The IOP-lowering medication, however, could not be significantly reduced within that time period. Conclusion Especially when combined with cataract surgery, ELT is a feasible minimally invasive procedure to lower the IOP on a mid- to long-term basis. Over the long term, however, IOP-lowering medication could not be reduced.

Refractive surgery is an increasingly popular procedure to decrease spectacle or contact lens dependency. The two most commonly used surgical techniques to correct myopia is Photorefractive keratectomy (PRK) and Femtosecond- Lasik (FS-LASIK)There are few publications that gathers such a long term follow up of both surgical techniques (2) Methods It has been performed a retrospective non-randomized study 509 PRK eyes and 310 FS-LASIK surgeries were followed for 10 years for the treatment of myopia and compound myopic astigmatism. Patients were followed up three months, one year, 2 years, 5 and 10 years. The safety index of both procedures was defined as a quotient between the postoperative BCVA (Best Corrected Visual Acuity) and the preoperative BCVA. The predictability is calculated as difference between the expected spherical equivalent and the achieved spherical equivalent. The efficacy index was calculated as a quotient between postoperative UCVA divided by the preoperative BCVA (3) Results. The results were: a safety index higher than 100% (109%) and an efficacy index of 82.4% after 10 years of PRK surgery in both groups. FS-LASIK was the safest surgery after 10 years and the most efficacy technique although in this case there were no statistically significant differences (4) Conclusions. All these data demonstrated better indexes for FS-LASIK

Hypospadias surgery is a humbling art form. The evolution of surgical techniques has made distal hypospadias outcomes favorable, but recent publications suggest that our complication rates for proximal hypospadias are much higher than previously reported. To explain these shortcomings, we examine the literature and focus on the lack of standardized documentation, the subsequent inability to objectify the severity of the phenotype, and the underestimation of complications due to lack of long-term follow up. The variability in surgical technique and the fact that the literature abounds with small case series from single institutions also limits our ability to compare outcomes. We believe that the use of standardized and scored phenotype assessments from diagnosis through the extended postoperative period will allow for improved scientific assessment of outcomes. This will facilitate multi-institution collaboration and tabulation of outcomes, allowing rapid data accumulation and assessment for this rare disorder. As surgeons, we must follow boys through puberty into adulthood and must honestly report our results in order to advance our surgical approach to this complicated problem.
