BACKGROUND
Congenital megalourethra is a urogenital anomaly characterized by a cystic dilatation and elongation of the penile urethra resulting from the absence and hypoplasia of the corpus spongiosum and corpus cavernosum, or anterior urethral valve. There are two clinical types: scaphoid and fusiform. Generally, the etiology is unknown, but it is thought to be a defect in mesodermal development. Fewer than 100 cases have been reported in the literature, and the exact incidence is unclear. In most cases, the surgical procedure is challenging and requires extensive reconstructive and/or replacement surgery.
CASE PRESENTATION
We present a 6-month-old boy suffering from a cystic dilatation of the penile urethra along with urine dribbling during micturition since birth. The patient was diagnosed with the scaphoid type of megalourethra and was operated on using reduction urethroplasty. On the 21st post-operative day, we removed the Foley catheter and followed the patient on two occasions (the 45th post-operative day and the 6th post-operative month) with excellent results.
CONCLUSION
The anagement of megalourethra depends on the clinical type. Meticulous surgical technique, the use of fine suture materials with careful handling, and fixation of the vascularized flap are the main principles of an acceptable result. Observation of erectile function and fertility require long-term follow-up.

Review
Hypospadias results from abnormal development of the penis that leaves the urethral meatus proximal to its normal glanular position. Meatal position may be located anywhere along the penile shaft, but more severe forms of hypospadias may have a urethral meatus located at the scrotum or perineum. The spectrum of abnormalities may also include ventral curvature of the penis, a dorsally redundant prepuce, and atrophic corpus spongiosum. Due to the severity of these abnormalities, proximal hypospadias often requires more extensive reconstruction in order to achieve an anatomically and functionally successful result. We review the spectrum of proximal hypospadias etiology, presentation, correction, and possible associated complications.

Review
The AdVance sling (American Medical Systems, Minnetonka, MN, United States of America) is a synthetic transobturator sling, which is a safe and effective minimally invasive treatment for mild to moderate stress urinary incontinence (SUI) in male patients. This article provides a step-by-step description of our technique for placement of the AdVance male sling, including details and nuances gained from surgical experience, advice for avoidance of complications and discussion on management of complications and sling failures. Patient selection is very important, including exclusion and preoperative treatment of urethral stenosis and bladder dysfunction. Previous pelvic radiation is a poor prognostic factor. In brief, the steps of sling placement are: (I) mobilization of the corpus spongiosum (CS); (II) marking and mobilization of the central tendon; (III) passage of the helical trocar needles exiting at the apex of the angle between the CS and inferior pubic ramus; (IV) fixation of the broad part of the sling body to the CS at the previous mark; (V) cystoscopy during sling tensioning; (VI) placement of a Foley urethral catheter; (VII) Subcutaneous tunnelling of the sling arms back toward the midline; (VIII) wound closure. The most common early postoperative complication is urinary retention but long-term retention is extremely rare. Management of sling failures include placement of an artificial urinary sphincter, repeat AdVance sling, urethral bulking agent or ProACT device.

Review
Excision and end-to-end anastomosis (EPA) has been the preferred urethroplasty technique for short bulbar strictures and is associated with an excellent functional outcome. Driven by concerns over the potential morbidity associated with dividing the urethra, therefore compromising spongiosal blood flow, as well as spongiofibrosis being superficial in the majority of non-traumatic bulbar strictures, the non-transecting technique for bulbar urethroplasty has been developed with the aim of achieving the same success as EPA without the morbidity associated with transection. This manuscript highlights the fundamental principles underlying the ongoing debate-transection or non-transection of the strictured bulbar urethra? The potential advantages of avoiding dividing the corpus spongiosum of the urethra are discussed. The non-transecting anastomotic procedure together with its various modifications are decribed in detail. Our experience with this technique is presented. Non-transecting excision of spongiofibrosis with preservation of well vascularised underlying spongiosum provides an excellent alternative to dividing the urethra during urethroplasty for short non-traumatic proximal bulbar strictures.

Review
OBJECTIVE
Penile cancer (PeCa) is a rare disease with a global incidence of 36 068 new cases in 2020. This accounts for 0.4% of all male malignancies. The surgical management of PeCa depends on the location of the tumour and depth of invasion. Here, we review the oncological and functional outcomes of penile-preserving surgery (PPS).
METHODS
A PubMed search until July 2021 on PPS for PeCa was conducted; a narrative review on different penile-sparing approaches and outcomes was performed.
RESULTS
PPS is now the standard of care in specialist centres for distal tumours not involving the corpus cavernosa. Laser therapy, glans resurfacing, and wide local excision are options for superficial lesions, whilst glansectomy is required for lesions invading into the corpus spongiosum.
CONCLUSION
PPS aims to preserve urinary and sexual function without compromising oncological outcomes.

We reviewed our experience in reconstructing forked corpus spongiosum (FCS) in distal/midshaft hypospadias repair and analyzed the efficacy of this surgical technique. From August 2013 to December 2018, 137 consecutive cases of distal/midshaft hypospadias operated by the same surgeon in Urology Department, Children's Hospital of Fudan University (Shanghai, China), were retrospectively analyzed. Sixty-four patients who underwent routine tubularized incised plate (TIP) or onlay island flap (ONLAY) surgery were included in the nonreconstructing group, and 73 patients who underwent reconstructing FCS during TIP or ONLAY surgery were included as the reconstructing group. Thirty-eight cases underwent TIP, and 26 underwent ONLAY in the nonreconstructing group, with a median follow-up of 44 (range: 30-70) months. Twenty-seven cases underwent TIP, and 46 underwent ONLAY in the reconstructing group, with a median follow-up of 15 (range: 6-27) months. In the nonreconstructing/reconstructing groups, the mean age at the time of surgery was 37.55 (standard deviation [s.d.]: 29.65)/35.23 (s.d.: 31.27) months, the mean operation duration was 91.95 (s.d.: 12.17)/93.84 (s.d.: 14.91) min, the mean neourethral length was 1.88 (s.d.: 0.53)/1.94 (s.d.: 0.53) cm, and the mean glans width was 11.83 (s.d.: 1.32)/11.56 (s.d.: 1.83) mm. Twelve (18.8%)/5 (6.8%) postoperative complications occurred in the nonreconstructing/reconstructing groups. These included fistula (5/2), glans dehiscence (3/0), diverticulum (1/2), residual chordee (3/0), and meatus stenosis (0/1) in each group. There was a significant difference in the overall rate of complications (P= 0.035). These results indicate that the technique of reconstructing FCS provides excellent outcomes with fewer complications in distal/midshaft hypospadias repair.

Review
INTRODUCTION
Broadly defined, urethral strictures are narrowing of the urethral lumen that is surrounded by corpus spongiosum, i.e., urethral meatus through the bulbar urethra. Urethral stenosis is narrowing of the posterior urethra, i.e., membranous urethra through bladder neck/prostate junction, which is not enveloped by corpus spongiosum. The disease has significant quality of life ramifications because many times younger patients are affected by this compared to many other urological diseases.
METHODS
A review of the scientific literature concerning urethral stricture, stenosis, treatment, and outcomes was performed using Medline and PubMed (U.S. National Library of Medicine and the National Institutes of Health). Abstracts from scientific meetings were included in this review.
RESULTS
There is level 3 evidence regarding the etiology and epidemiology of urethral strictures, stenoses, and pelvic fracture urethral injuries. Outcomes data from literature regarding intervention for urethral stricture are largely limited to level 3 evidence and expert opinion. There is a single level 1 study comparing urethral dilation and direct vision internal urethrotomy. Urethroplasty outcomes data are limited to level 3 case series.
CONCLUSIONS
Progress is being made toward consistent terminology, and nomenclature which will, in turn, help to standardize treatment within the field of urology. Treatment for urethral stricture and stenosis remains inconsistent between reconstructive and nonreconstructive urologists due to varying treatment algorithms and approaches to disease management. Tissue engineering appears to be future for reconstructive urethral surgery with reports demonstrating feasibility in the use of different tissue substitutes and grafts.
