Personalized Surgical Management Offers Full Restitution and Unimpaired Quality of Life to Patients with Duplex Kidneys and Associated Pathologies: 30-year Follow-up at a Tertiary Referral Center.

Background: Duplex kidneys may be associated with additional pathologies with an indication for surgery. Various surgical approaches have been described. However, little is known about long-term outcomes and quality of life (QoL) for these patients.

The SIGHT questionnaire: A novel assessment tool for Satisfaction In Genital Hypospadias Treatment.

Purpose: Psychosexual development is currently underrepresented in hypospadias outcome research. The aim of this study was to develop and validate a questionnaire addressing psychosexual long-term satisfaction, specifically of adolescent patients, after hypospadias repair.

Materials And Methods: In a multistep participative design we identified key interests of adolescent patients with hypospadias.

Analgesia-free flexible ureteroscopic treatment and laser lithotripsy for removal of a large urinary stone: a case report.

Introduction: Urinary stone formation is a frequent complication after continent urinary tract diversion and can require complex surgical management. Therapy options include open, percutaneous, transurethral, or transstomal stone fragmentation and extraction. The transstomal approach is considered to be one of the more complex treatment modalities.

Single-Incision Transumbilical Surgery (SITUS) versus Single-Port Laparoscopic Surgery and conventional laparoscopic surgery: a prospective randomized comparative study of performance with novices in a dry laboratory.

Purpose: To evaluate the Single-Incision Transumbilical Surgery (SITUS) technique as compared to an established laparoendoscopic single-site surgery (LESS) technique (Single-Port Laparoscopic Surgery, SPLS) and conventional laparoscopy (CLS) in a surgical simulator model.

Methods: Sixty-three medical students without previous laparoscopic experience were randomly assigned to one of the three groups (SITUS, SPLS and CLS). Subjects were asked to perform five standardized tasks of increasing difficulty adopted from the Fundamentals of Laparoscopic Surgery curriculum.

Game-based e-learning is more effective than a conventional instructional method: a randomized controlled trial with third-year medical students.

Background: When compared with more traditional instructional methods, Game-based e-learning (GbEl) promises a higher motivation of learners by presenting contents in an interactive, rule-based and competitive way. Most recent systematic reviews and meta-analysis of studies on Game-based learning and GbEl in the medical professions have shown limited effects of these instructional methods.

Objectives: To compare the effectiveness on the learning outcome of a Game-based e-learning (GbEl) instruction with a conventional script-based instruction in the teaching of phase contrast microscopy urinalysis under routine training conditions of undergraduate medical students.

The glandular resection and central embedding modification (GRACE) in Duckett and Barcat hypospadias repair.

Introduction: We recently reported a novel modification of the Barcat technique termed glandular resection and central embedding (GRACE). Here, we report results from a large patient population and apply this modification also to Duckett hypospadias repair.

Patients And Methods: We retrospectively evaluated 488 patients who had undergone primary or secondary hypospadias repair by Barcat or Duckett using the GRACE modification.

Glandular resection and central embedding in hypospadias repair--a novel modification of the Barcat technique.

Purpose: Urethrocutaneous fistula and urethral or meatal stricture, to date, remain the commonest complications of hypospadias repair, with increased tissue tension being a major cause of failure. We developed a novel technique comprising glandular resection and central embedding of the neourethra to specifically address this critical issue. We report the results of the first 112 procedures, of which 7 cases were a secondary hypospadias repair.

Pre-bent instruments used in single-port laparoscopic surgery versus conventional laparoscopic surgery: comparative study of performance in a dry lab.

Background: Different types of single-incision laparoscopic surgery (SILS) have become increasingly popular. Although SILS is technically even more challenging than conventional laparoscopy, published data of first clinical series seem to demonstrate the feasibility of these approaches. Various attempts have been made to overcome restrictions due to loss of triangulation in SILS by specially designed SILS-specific instruments.

Difficulties in diagnosis and treatment of 5alpha-reductase type 2 deficiency in a newborn with 46,XY DSD.

Background/aims: Steroid 5alpha-reductase deficiency (MIM*607306) caused by mutations in the SRD5A2 gene is characterized by a predominantly female phenotype at birth and significant virilization at puberty. The undermasculinization at birth results from low dihydrotestosterone (DHT) levels during fetal development as the type 2 isoenzyme activity is reduced. In puberty, when the type 1 isoenzyme activity increases, significant virilization occurs.
