Surgical and functional outcomes of Dorsal Inlay Graft urethroplasty in revision vs primary hypospadias repair in the pediatric age.

INTRODUCTION: Over the years, Dorsal Inlay Graft (DIG) urethroplasty has gained worldwide acceptance for primary hypospadias repair. However, its safety and effectiveness for revision surgery are yet to be proven. OBJECTIVE: The aim of the study is to assess and compare complication rates and functional outcomes of DIG surgery in revision versus primary hypospadias repair. MATERIAL AND METHODS: We carried out a retrospective analysis of data collected from 53 consecutive DIG urethroplasties performed by a single surgeon at our institution. Patients were stratified in two groups - primary repair and redo-urethroplasty. For each group, we recorded standard pre-operative characteristics, surgical technicalities, complication rates and uroflowmetry parameters. RESULTS: Out of 53 DIG urethroplasties, 21 (39.6 %) where primary and 32 (60.4 %) were re-do. As expected, the two groups differed for median age at surgery: 20 months for primary and 68.5 months for revision surgery (p < 0.001). Additionally, all 21 (100 %) primary interventions were performed with a preputial graft, whereas among revision DIG urethroplasties only 2 (6.3 %) where preputial and 30 (93.8 %) were buccal (p < 0.001). Catheterization time (7 vs 8 days, p = 0.155) and postoperative complication rates (14.3 % vs 9.4 %, p = 0.581) were comparable between the primary and revision surgery group, respectively (all p > .05). Forty-two of the 53 patients underwent uroflowmetry during follow-up. Of these, 19 (63 %) patients presented with abnormal uroflowmetry and 11 (37 %) had equivocal parameters with no difference between the two groups. DISCUSSION: Dorsal Inlay Graft urethroplasty has long been known to be safe and effective for primary hypospadias repair. On the other hand, data on dorsal inlay graft urethroplasty as a salvage surgery after primary hypospadias repair failure is scarce. Surprisingly, according to our findings, surgical outcomes and complication rates are comparable between primary and revision hypospadias cases. Additionally, our results in the redo group are absolutely encouraging if compared to those reported in the literature for the same subset of patients. CONCLUSIONS: According to our findings, DIG urethroplasty is a safe and effective option to treat revision hypospadias repair.

Laparoscopic robotic-assisted "keel" bladder neck construction.

INTRODUCTION: Robotic technology has gained popularity allowing performance of several complex and difficult reconstructive procedures. This video demonstrates the advantages of the robotic approach for a "keel" bladder neck construction in an obese patient. MATERIAL AND METHODS: A 13 year-old-girl (BMI = 28) already treated elsewhere for a uro-genital sinus (Total Urogenital Mobilization) has been evaluated for disturbing persistent total urinary incontinence. Cisto-colposcopy revealed an extremely short and tortuous urethra. Bladder neck was wide open and incompetent. Video-Urodynamic evaluation showed a bladder with a capacity of 280 mL with low voiding pressures (14-16 cmH20) and continuous urinary leakage. MAG3 scan confirmed normal renal function. Thus, the girl underwent a laparoscopic robotic-assisted "keel" bladder neck construction. RESULTS: The patient was discharged on 5th post-operative day without complications. After 4 years she is voiding spontaneously (300 cc) without post-void residuals. She has presented a persistent mild stress incontinence successfully treated with subsequent endoscopic bulking agent injection. CONCLUSIONS: Robotic access to the bladder neck region is an excellent option with ideal anatomical exposure compared to conventional open surgery, especially in obese patients. The "keel" procedure allows to reconfigure and tubularize a wide and incompetent bladder neck creating a continent funnel without the absolute need of concomitant ureteric reimplantation.

Prevalence of pain in the departments of surgery and oncohematology of a paediatric hospital that has joined the project "Towards pain free hospital".

BACKGROUND: Among hospitalized adults and children pain is undertreated. This study wants to assess the effectiveness of pain therapy in two departments of a large children's hospital. MATERIALS AND METHODS: During a single day work three committees, administering a questionnaire to patients or parents, have evaluated the adherence to international recommendations (JCI and WHO) in the management of analgesic therapy. Patient demographics, prevalence and intensity (moderate and/or severe) of pain (during hospitalization, 24 hours before and at the time of the interview), analgesia (type, route, duration and frequency of administration) and Pain Management Index (=analgesic score-pain score) were recorded. RESULTS: 75 patients participated in the study (age: 2 months up to 24 years, mean 7.8 ± 6). During hospitalization 43 children (57%) had no pain while 32 (43%) have experienced pain. 22 children (29 %) had pain 24 hours before and 12 (16%) at the time of the interview. The average value of the PMI was -0.8±1.3 with a minimum of -3 and a maximum of +2: 60% (19) of the children had a PMI less than 0 (undertreated pain) while 40% (13) had a value=or>0. Out of 32 patients who needed an analgesic therapy 14 (44%) received an around-the-clock dosing, 8 (25%) an intermittent therapy and 10 (31%) no treatment.17 (77 %) were the single drug therapy and 5 (23%) the multimodal ones. CONCLUSIONS: The prevalence of pain in the two departments is high. The main cause is that knowledge is not still well translated into clinical practice.

Late-presenting right congenital diaphragmatic hernia with severe hypotrophy of the right lobe of the liver.

INTRODUCTION: Congenital diaphragmatic hernia (CDH) presenting after 30 days of life is unusual and has a variant pattern of presentation. PRESENTATION OF CASE: We present a death case occurred to a 34-days-old infant. The infant arrived to our emergency department in cardiac arrest after having suffered from intermittent acute abdominal pain. Autopsy confirmed the presence of a right CDH, with herniation of the right lobe of the liver into the thorax. DISCUSSION: Most of the cases of CDH are diagnosed prenatally or in the neonatal period. However, some patients do not develop symptoms until after the neonatal period. The relevance of our case is the co-existence of right CDH and important hypotrophy of the right lobe of the liver. CONCLUSIONS: Evidence of this phenomenon represents an absolute novelty in the extant scientific literature. Even if rare, we suggest to suspect the presence of CDH in fetus with disparity in right and left liver lobe at prenatal ultrasound.
