This cross-sectional comparative study aimed to compare serum L-carnitine and 25(OH)D levels between men with ED non-responding for oral sildenafil citrate and healthy volunteers. Overall, 192 men, recruited from two University Hospitals, were allocated into two equal groups of matched age; healthy potent men and men with ED non-responders for oral sildenafil citrate. Oral sildenafil citrate non-responders self-reported inadequate erectile responses after four attempts using 100 mg with the manufacturer's guidelines relative to meals, associated medications, and sexual stimulation/arousal. Exclusion criteria were: diabetes, cardiovascular disorders, beta blockers treatment, morbid obesity, thyroid disorders, post-radical prostatectomy, and hepatic/renal failure. All participants were subjected to; history taking, clinical examination, validated IIEF-5 questionnaire, estimation of serum L-carnitine by calorimetric method and serum 25(OH)D by ELISA method. Compared with potent controls, ED men non-responders for oral sildenafil citrate showed significant decreases in the mean serum L-carnitine level (16.8 ± 3.6 uM/L versus 66.3 ± 11.9 uM/L, P = 0.001), the mean serum 25(OH)D level (21.2 ± 7.1 ng/ml versus 54.6 ± 7.9 ng/mL, P = 0.001) and IIEF-5 score (7.8 ± 2.6 versus 23.9 ± 1.3). Serum L-carnitine showed significant positive correlation with IIEF-5 scores (r = 0.873, P = 001), serum 25(OH)D (r = 0.796, P = 0.001) and significant negative correlation with the age (r = -0.515, P = 0.001). Serum 25(OH)D showed significant positive correlation with IIEF-5 scores (r = 0.855, P = 0.001) and significant negative correlation with the age (r = -0.223, P = 0.005). It is concluded that normal homeostasis of serum L-carnitine and 25(OH)D play a role in male sexual health being significantly decreased in ED non-responding for oral sildenafil citrate.

Background/aim: Approximately 20% of undescended testes (UDT) are bilateral. It is unclear whether bilateral orchidopexy (BO) should be undertaken synchronously (SBO) or metachronously (MBO). Our aim was to investigate current UK practice and the complications of SBO vs MBO., Materials & Methods: Following approval of BAPS and BAPU ethics committee, a survey was circulated to UK consultant pediatric surgeons and urologists regarding practice. A departmental retrospective review was additionally carried out for patients undergoing BO between 2005 and 2017., Results: Forty-three consultant surgeons from 20 centres completed the survey. Overall, SBO was preferred by 70% for bilateral palpable UDT versus 30% for bilateral impalpable UDT. When one side was palpable and the other impalpable, 70% preferred SBO. Pediatric urologists were significantly more likely to undertake SBO than pediatric general surgeons. One hundred eighty-eight patients (376 testicular units) were identified who had undergone BO with a median follow up of 9 months. 144/188 (76.6%) underwent SBO, while 44 had MBO. There was no statistical difference in the complication rate between the two groups (7.6% in SBO vs 9.1% in MBO; p = 0.66)., Conclusions: The majority of the responding UK consultants, in particular pediatric urologists, favor SBO. This potentially offers a reduction in cost, more rapid completion of treatment, and is not associated with additional complications by comparison to MBO. We recommend SBO to be standard practice for bilateral UDT whenever possible., Level of Evidence: Level III, Retrospective Comparative Study., (Copyright © 2018 Elsevier Inc. All rights reserved.)

We present a video of our technique for resection of a large prostatic utricle (PU) in a patient who presented initially with disordered sexual development. His karyotype was 46XY, and phenotypically had penoscrotal hypospadias, bifid scrotum, and retractile right testis. An initial micturating cystourethrogram (MCUG) demonstrated the utricle but failed to cannulate the bladder. Being asymptomatic, we carried out staged repair of his hypospadias. Later, he started to have recurrent epididymo-orchitis with resistance to multiple antibiotics. Examination under anaesthesia was done and ruled out meatal or neo-urethral strictures. A subsequent MCUG demonstrated the large utricle and its relation to the bladder. We carried out a cystoscopic-assisted laparoscopic excision. There has been no consensus about the best surgical approach to resect a PU and most known procedures involved extensive pelvic dissection and carried a significant risk of damage to the pelvic nerves. The laparoscopic approach seems to be promising in this field as it provides proper view of the deep pelvis with reasonable magnification, less dissection and shorter postoperative pain and scarring. Cystoscopic assistance in this technique was a great addition to provide counter-traction movement and facilitate proper dissection., (Copyright © 2017 Journal of Pediatric Urology Company.
