PURPOSE Management for blunt trauma with breach of the renal capsule or bladder (extraperitoneal) has largely become nonsurgical since a conservative approach proved to be effective and safe. Currently the recommendation for managing testicular rupture is surgical exploration and débridement or orchiectomy. We report outcomes in boys diagnosed with testicular rupture and treated without surgical intervention. MATERIALS AND METHODS In the last year we conservatively treated 7 consecutive boys with delayed presentation of testicular rupture after blunt scrotal trauma. Patients were treated with scrotal support, antibiotics to prevent abscess, rest, analgesics and serial ultrasound. We report clinical information and outcomes. RESULTS The 7 boys were 11 to 14 years old and presented 1 to 5 days after injury. Trauma was to the left testis in 3 cases and to the right testis in 4. Patients presented with mild to moderate pain and similar scrotal swelling. Ultrasound findings consistently revealed hematocele and increased echogenicity. Blood flow was present in the injured portion of the testes in 3 cases and to the remainder of the affected testicle in 6 of the 7 boys. In the remaining boy an adequate waveform was not seen in either testicle, which the radiologist thought was secondary to prepubertal status. Other findings included scrotal edema, irregular contour and seminiferous tubule extrusion. Followup was greater than 6 months in all cases. Five boys were seen at the office and the 2 remaining had telephone followup. In all cases hematocele resolved, testicular size stabilized without atrophy and echogenicity normalized in the 5 patients with followup ultrasound. One patient required surgical repair of hydrocele 4 months after trauma but no other patient needed surgical exploration. No abscess or infection developed. CONCLUSIONS A conservative approach in a select group of adolescent boys with testicular rupture can result in resolution of the fracture and maintenance of testicular architectural integrity.

OBJECTIVE To assess the long-term occurrence of hydroceles and varicocele recurrence in patients receiving lymphatic sparing laparoscopic varicocelectomy (LSLV) compared to those receiving plain laparoscopic varicocelectomy (PLV), and also to assess the growth of testicular volume postoperatively. METHODS We employed a standard three-trocar configuration. The spermatic vessels were identified in the retroperitoneum above the internal inguinal ring. Lymphatics were dissected free from the spermatic artery and veins based on laparoscopic appearance. The spermatic artery and veins were divided between plastic locking clips. We performed a retrospective chart review of all pediatric patients who underwent laparoscopic varicocelectomy between June 2003 and January 2009. RESULTS Of a total of 97 patients, 67 underwent LSLV with mean follow-up of 45.8 ± 20.7 months and 30 underwent PLV with mean follow-up of 40.8 ± 25.3 months (p = 15). There was a 4.5% hydrocele rate in the LSLV group compared to 43.3% in the PLV group. Of the patients who underwent a PLV and subsequently developed a hydrocele, 31% (n = 4) required a hydrocelectomy, vs none of those who developed a hydrocele after LSLV. Varicocele rate was 6% in the LSLV group vs 3.3% in the PLV group. However, when the artery was not preserved, the probability of recurrence in the LSLV group was 1.3%. Time to hydrocele formation was 16 months in the LSLV group vs 37 months in the PLV group. There was catch-up testicular growth in both groups. CONCLUSIONS There appears to be increased risk of need for a hydrocelectomy after a PLV as compared to LSLV. Performing a lymphatic sparing, non-artery preserving, laparoscopic varicocelectomy has success and complication rates comparable with those of subinguinal microsurgical varicocelectomy. There appears to be excellent catch-up testicular growth with either laparoscopic varicocelectomy technique.

PURPOSE Buccal mucosa is the favored graft material for patients with long urethral defects and a paucity of skin. Since 2007, we have used the novel tunneled buccal mucosa tube graft urethroplasty technique in these patients. We describe this operative technique and report our surgical and functional outcomes. MATERIALS AND METHODS Between 2007 and 2013, 37 males with proximal hypospadias underwent tunneled buccal mucosa tube graft urethroplasty. After the penile shaft was optimized at a prior stage a free buccal graft was tubularized and tunneled under the intact ventral shaft skin and into the glans. We retrospectively reviewed all charts to report our results. We assessed uroflowmetry and bladder ultrasound for post-void residual urine. RESULTS The overall complications rate in 34 patients with more than 1-year followup was 32% (11), including fistula in 5, proximal stricture in 4 and meatal stenosis in 2. In the first 10 patients a total of 7 complications (70%) developed but there were only 4 complications in the next 24 (16%). Surgeon experience was the only significant predictor of complications (p = 0.003). We obtained uroflow and post-void residual urine data on 13 of 37 patients, of whom 9 achieved a normal flow pattern and post-void residual urine, and 4 had a blunted flow pattern. CONCLUSIONS The novel technique of the tunneled buccal mucosa tube graft in patients with proximal hypospadias represents a good alternative for a long urethroplasty in patients with a paucity of skin. After the learning curve plateaus the rate and degree of complications decrease. Furthermore, voiding function is adequate, as assessed by uroflow studies and post-void residual urine measurement.

Male and female aphallia associated with severe urinary tract dysplasia

Ariella A. Friedman; Paul Zelkovic; Israel Franco; Lane S. Palmer

INTRODUCTION Aphallia is exceedingly rare (1/30 million births). Previous reports have provided limited detail on associated urinary tract findings. OBJECTIVE We reviewed urinary tract anomalies in two boys with aphallia (patients 1 and 2) and a girl with urinary tract dysplasia, a similar external appearance and lack of corporal tissue (patient 3), also consistent with aphallia. CASE REPORTS (FIGURE) Patients 1 and 2 both had a 46XY karyotype, bilateral descended testes in well-formed scrotums, and posterior skin tags containing rudimentary urethras. Patient 1 had a focal area of urethral narrowing; a posterior bladder diverticulum, which drained a ureter; bilateral grade 5 vesicoureteral reflux, with a right partial renal duplication; and hydronephrosis of all moieties. Patient 2 had posterior urethral valves and a bladder diverticulum. Right ureterovesical junction obstruction required a tapered reimplant and later conversion to right-to-left transureteroureterostomy. Patient 3 had a 46XX karyotype and fused, well-formed labia majora. A posterior skin tag was associated with a stenotic urogenital sinus, beyond which were a vagina posteriorly and a right refluxing ureter anteriorly. The left ureter was absent, and a miniscule pouch represented a maldeveloped or absent bladder. Laparoscopy revealed ovaries and normal Müllerian structures. Bilateral renal dysplasia necessitated renal transplant and the creation of an ileocecal neobladder and Mitrofanoff channel. Corporal tissue was diminutive or absent in all. DISCUSSION We see from these three patients that corporal tissue absence can occur in both male and female patients. We propose that the term aphallia can apply to both sexes, as it is the absence of corporal tissue that defines this condition. This is the only report to include and characterize findings in both male and female aphallia patients. Labioscrotal folds develop with a smooth appearance, and, posteriorly, a urethral orifice or Urogenital (UG) sinus with skin tag may be seen. Obstruction at the level of the urethra was common. Severe urinary tract dysplasia was seen in all, a finding not consistently seen or characterized in previous reports. CONCLUSION In girls with severe urinary tract dysplasia and characteristic genital ambiguity, aphallia should be considered. Co-occurrence of aphallia and severe urinary tract dysplasia warrants further urinary tract imaging in all aphallia patients, including voiding cystourethrography, renal bladder ultrasound, and serum creatinine level. Urinary tract reconstruction may be performed without hampering future penile reconstruction, due to modern phallic reconstructive techniques.

Conjoined twins are identical twins that have incompletely separated in utero. The prognosis for conjoined twins is poor and management in a skilled tertiary care centre is paramount for definitive care. We describe our experience with a telemedical consultation on conjoined twins in The Dominican Republic from our eHealth centre in Valhalla, NY. The patients were two month old, female, pygopagus conjoined twins. A multidisciplinary teleconference was initiated with the patients, their family, the referring paediatrician and our team. Based on this teleconsultation, the team felt as though the twins may be amenable to a surgical separation. They presented to our centre in Valhalla, NY, for a detailed physical examination and series of imaging studies. Soon after, the patients underwent a successful 21 h separation procedure and were discharged 12 weeks later. To our knowledge, this is one of the first reports of an international teleconsultation leading to a successful conjoined twin separation procedure.

OBJECTIVE To report the first exclusively pediatric series of robot-assisted urachal remnant excisions in children. METHODS We reviewed the medical records of all children who underwent robot-assisted excision of urachal remnants from 2010 to 2016. For the procedure, a 3-port approach was performed in all cases. Excision of the urachus was performed, along with partial cystectomy if there was clear or suspected bladder involvement. Outcomes and complications were reviewed. RESULTS Sixteen cases of robotic urachal excision were performed during the study period in patients aged 0.8-16.5 years. Complete excision was accomplished in all cases with no conversions. Partial cystectomy was performed in 11 cases, in which a urinary catheter was left for 1 day in all cases (no catheter was left in the absence of partial cystectomy). The only complication was a bladder leak requiring open surgical repair. There were no bowel injuries or hernias. The median operative time was 107 minutes. The length of stay was 2 days with partial cystectomy and 1 day without partial cystectomy. All patients were well at follow-up. CONCLUSION We report the largest known series of robot-assisted urachal remnant excisions in children, demonstrating this minimally invasive approach to be safe and effective.

Michael B. Rothberg; Amul Bhalodi; Edward F. Reda; Paul Zelkovic; Israel Franco

A 16-year-old female patient presented to our emergency department with a left upper extremity radiculopathy prompting several imaging studies. Magnetic resonance imaging of the neck revealed multiple cervical vertebrae lesions and computed tomography imaging demonstrated a 15-cm calcified mass originating from the left kidney and extending into the surrounding structures. Pathologic assessment of the open left radical nephrectomy specimen revealed a primary renal mesenchymal chondrosarcoma, a tumor that has only been documented in 5 prior case reports in the literature.

SURGICAL APPROACH TO THE INCOMPLETELY DESCENDED TESTIS AFTER LAPAROSCOPIC ORCHIDOPEXY

Paul Zelkovic; Lori Dyer; Edward F. Reda; Israel Franco

Introduction and Objective: Laparoscopic orchidopexy has become a well accepted modality for the treatment of intraabdominal testis. As with all surgery, occasionally we will have an imperfect result and in other cases we have chosen not to do a vessel transection and left the testis outside of the scrotum. A review of the literature reveals no prior description of a reoperative technique to further descend the testis that has not been fully brought down after laparoscopic orchidopexy. Methods: We reviewed our records of all patients that underwent redo orchidopexy over the last 12 years after an initial laparosopic orchidopexy. We found 11 patients (12 testis) that underwent surgery to further the descend the testis. 10/11 patients received HCG preoperatively. All the testis were initially approached via an inguinal incision near the neoring. Careful mobilization of the testis and the cord is all that is necessary but at times there has been a need to extend the dissection intraabdominally to get additional length. Once adequate length is obtained the testis is placed back in the dartos pouch as with a regular orchidopexy. Results: We found that all 12 testis were adequately descended using the described dissection. In 10 patients that received HCG the dissection was facilitated and adequate length was achieved without any additional intraabdominal dissection. The one patient that did not receive preop HCG stimulation required extensive intraabdominal dissection but this patient had also undergone one prior attempt to bring the testes down that had been unsuccessful. In no instance was atrophy of the testis noted post operatively. Conclusions: It appears simple dissection of the testis that is incompletely descended after laparoscopic orchidopexy is highly successful especially if HCG stimulation is used preoperatively. Access to the abdominal cavity is simple and dissection along the cord can easily be done if additional length is needed.
