RESUMO
PURPOSE: Urological management of Cloacal Malformation (CM) focuses on preserving renal function and continence. Study aim was to analyze urinary and intestinal outcomes in CM patients, considering the length of common channel (CC) and presence of occult spinal dysraphism (OSD). METHODS: Retrospective review of CM treated at our institution by a multidisciplinary team from 1999 to 2020. Patients with follow-up < 2.5 years were excluded. Length of CC, renal function, urinary and bowel outcomes, presence of associated anomalies (especially OSD) were evaluated. RESULTS: Twenty patients were included, median age at follow-up: 8 years (4-15). A long CC > 3 cm was described in 11 (55%). Chronic kidney disease was found in 3 patients. Urinary continence was achieved in 8/20 patients, dryness (with intermittent catheterization) in 9/20. Fecal continence was obtained in 3/20, cleanliness in 14 (under bowel regimen). OSD was present in 10 patients (higher prevalence in long-CC, 73%). Among OSD, 1 patient reached fecal continence, 7 were clean; 2 achieved urinary continence, while 6 were dry. CONCLUSIONS: Length of CC and OSD may affect urinary and fecal continence. An early counseling can improve outcome at long-term follow-up. Multidisciplinary management with patient centralization in high grade institutions is recommended to achieve better results.

AIM: In paediatric and adult patients with neurogenic bowel, transanal irrigation (TAI) of the colon has gained popularity due to the introduction of a specifically designed device. The aim of this pilot study was to present the results of TAI using the Peristeen(®) TAI system in a group of paediatric patients with anorectal malformation (ARM) and congenital or acquired spinal cord lesions (SCLs). METHOD: Eight Italian paediatric surgery and spina bifida centres participated in the study. The inclusion criteria were age between 6 and 17 years, weight above 20 kg and unsatisfactory bowel management. Patients with chronic inflammatory bowel disease, mental disability and surgery within the previous 3 months were excluded. At the beginning of treatment (T0) and after 3 months (T1) the Bristol scale, a questionnaire assessing bowel function, and two questionnaires on quality of life (QoL) for patients aged 6-11 years (CHQ-pf50) and 12-17 years (SF36) were administered. RESULTS: Eighty-three patients were enrolled, and seventy-eight completed the study (41 ARMs, 37 SCLs). At T1, constipation was reduced in ARMs from 69% to 25.6% and in SCLs from 92.7% to 41.5%, faecal incontinence in ARMs from 50% to 18.6% and in SCLs from 39% to 9.8% and flatus incontinence in ARMs from 20.9% to 9.8% and in SCLs from 31.7% to 10%. At T0, the Bristol Stool Scale types were 1-2 in 45% of ARMs and 77.5% of SCL patients, whereas at T1 types 1-2 were recorded in only 2.5% of SCL patients. QoL improved in both groups. In the younger group, a significant improvement in QoL was recorded in ARM patients for eight of nine variables and in SCL patients for seven of nine variables. CONCLUSION: This study showed that Peristeen TAI resulted in a significant time reduction in colonic cleansing, increased independence from the carer and improved QoL in paediatric patients with ARMs and SCLs.

PURPOSE: Epididymo-orchitis (EO) is infrequently reported in anorectal malformation (ARM) cases. Therefore, it is difficult to assess its risk factors. METHODS: A total of 110 male patients who were operated on for ARM at the same Institution over a period of 13 years were contacted. Association was assessed between EO and the following: spinal dysraphism (SD), symptomatic VUR (VUR), and bowel management (BM) requiring enemas. The data were analyzed with the Chi-square test. RESULTS: A total of 89 patients were contacted. Ten cases of EO were found, and all occurred in patients with recto-urethral (RU) fistula after reconstruction. The patients' age at first episode ranged between 4 and 11 years. RU fistula patients experiencing EO (Group A, 10 patients) were compared with those without EO (Group B, 33 patients). VUR occurred in 9/10 cases in Group A and in 13/33 cases in group B (Chi-square 7.8658, p = 0.005038). SD was present in 4/10 cases in group A and in 13/33 cases in Group B (Chi-square 0.0434, p = 0.83491). A total of 8/10 cases in Group A and 12/33 cases in Group B were on BM (Chi-square 5.87, p = 0.0015). CONCLUSIONS: EO occurs in approximately in 20 % of male cases with ARM, and recto-urinary communication and should be considered the primary diagnosis in the presence of testicular pain. This could avoid unnecessary surgical exploration, and the family should be counseled about this subject.

Objective. To present a case of isolated ascites secondary due to urogenital abnormalities (urogenital sinus) without any other prenatal ultrasound marker. Method. A 36-year-old woman with prenatal isolated ascites delivered a female baby, weighing 2.285 g; ascites was drained at birth and the baby underwent several episodes of urinary retention prior to undergoing X-ray investigations. Results. A voiding cystourethrogram revealed a short urogenital sinus: a vesicostomy was performed. A vaginoscopy revealed double vagina with a large posterior vagina. A posterior sagittal anorectal pull-through with genitoplasty was performed at 2 years old with 1-year follow-up. Conclusions. Though rare, a urogenital abnormality is to be suspected in fetal ascites cases with negative viral tests and no cardiac anomalies. The most common ultrasound marker of such abnormalities (fluid filled cavity) may be missing because of complete drainage of urine through the tubes into peritoneum.
RESUMO
OBJECTIVE: Oligohydramnios (OA) is nowadays regarded as one of the best markers of renal function (RF) impairment in bladder outlet obstruction (BOO) detected in utero. As such, its onset is usually early and progressive because of decline in fetal urine production. A series of acute OA complicating pregnancies with BOO has never been reported. METHODS: Over a 7-year period, 5 fetuses with in utero suspicion of BOO exhibited an abrupt decrease of amniotic fluid after the 30th week of gestation. RESULTS: All fetuses were delivered by cesarean section: diagnosis was posterior urethral valves in 3 cases, urethral atresia in 1, and prune-belly syndrome in 1. Urologic work-up demonstrated a unilateral vesicoureteral reflux dysplasia (VURD syndrome) in all 5 fetuses. RF at 1 year was normal in 4 fetuses and impaired in 1. CONCLUSIONS: Besides obstetrical reasons, OA may also have acute onset occurring in the presence of anomalies of the urinary tract; although diagnosis is almost always BOO, functional and anatomical characteristics of the urinary tract are those of VURD syndrome with a non-functioning, refluxing renal unit. The associated acute OA/VURD syndrome may represent a milder expression of a pop-off mechanism advocated in this syndrome with a more favorable prognosis than progressive OA detected early in pregnancy.

PURPOSE: We evaluated pain tolerability and the preliminary results of percutaneous tibial nerve stimulation (PTNS) in children with unresponsive lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: A total of 23 children 4 to 17 years old with LUTS refractory to conventional treatment underwent PTNS at 12, 30-minute weekly sessions. Ten patients had idiopathic overactive bladder, 7 were in nonneurogenic urinary retention and 6 had neuropathic bladder. Ten children were carefully evaluated for pain during needle insertion and electrical stimulation using certain scoring systems, namely the faces pain rating scale, Children's Hospital of Eastern Ontario pain scale, visual analogue scale and Questionario Italiano del Dolore. Evaluation was done at the first, sixth and last sessions. An anxiety-depression test was administered. All 23 children underwent clinical and urodynamic evaluation before and after treatment. RESULTS: All except 1 patient completed treatment. An anxious-depressive trait was found in 7 of 10 children/parents on anxiety-depression testing. Regarding pain, the faces pain rating scale never showed the severe pain face, the Children's Hospital of Eastern Ontario scale showed signs of pain at the beginning of each stimulation but not at the end, and the visual analog scale generally showed a low score with a further decrease during the first (p = 0.05), sixth (p = 0.03) and twelfth (p = 0.02) sessions. The Questionario Italiano del Dolore score was significantly related to the affective component of pain (p = 0.002) and it decreased between the first and last sessions. The 10 children with overactive bladder had symptom improvement in 80%, incontinence was cured in 5 of 9 and urodynamics showed normalization of cystometric bladder capacity in 62.5% with no more unstable contractions in those who became continent. Symptoms improved in 71% of the children in urinary retention. One of 3 and 4 of 7 patients had incontinence and post-void residual urine cured, respectively. Urodynamics showed an improved detrusor pressure at maximum flow (p = 0.009) and flow rate (p = 0.005). Symptoms and urodynamics did not significantly change in the neuropathic bladder group. CONCLUSIONS: PTNS is safe, minimally painful and feasible in children. It seems helpful for treating refractive nonneurogenic LUTS.

OBJECTIVE: To evaluate 10 years of experience, and thus define the occurrence and causes, of neurogenic lower urinary tract dysfunction in children with pelvic neoplasms treated by surgery. PATIENTS AND METHODS: From 1991 to 2000, 33 children were operated by the same surgeons for pelvic neoplasms; 11 were analysed, comprising four each with sacrococcygeal teratoma (ST) and ganglioneuroma, and one each with yolk sac tumour (YST), neuroblastoma and myofibroblastic bladder sarcoma (MBS). The other patients were not assessed because eight had died or were in severe progression, three were treated by bladder substitution and the others were lost to follow-up or refused a urological evaluation. All 11 children were evaluated at >/= 6 months after surgery with a questionnaire about bowel and voiding habits, a neurological and orthopaedic assessment, a noninvasive urodynamic study, renal ultrasonography and spinal and pelvic magnetic resonance imaging (MRI). All patients with signs of bladder dysfunction were evaluated by a pressure-flow study. The results were analysed for surgical approach and anatomical involvement, i.e. group A, extensive surgery for complete tumour excision in the sacral area (ST and YST); group B, surgery for tumour resection in the paraspinal ganglia area (neuroblastoma and ganglioneuroma); and group C, bladder tumour with partial bladder resection (MBS). RESULTS: Eight patients had signs or symptoms related to bladder sphincter dysfunction. One child refused the invasive urodynamic evaluation, leaving seven for analysis (two each ST and ganglioneuroma, one each YST, neuroblastoma and MBS). The urodynamic findings were normal in three children. On spinal and pelvic MRI a presacral lipoma with syringomyelia was discovered in one child with ST. Eight children had bladder dysfunction and two had no neurogenic damage (which was only in sacral tumours); in one child it was related to an upper motor neurone lesion from spinal dysraphism and in the other to a lower motor neurone lesion from surgical injury to the splanchnic nerves. Patients operated for paraspinal tumours had more bladder dysfunction but no signs of neurogenic damage, as did the patient with partial bladder resection. However in Group B, there may have been a transient or incomplete nerve injury in one patient. CONCLUSIONS: Deficits of parasympathetic, sympathetic and somatic innervation of the bladder and the urethra may occur in children after surgery for pelvic neoplasms, related to minor or major surgical trauma. In ST, a tethered cord may be associated with mixed neurogenic damage. Knowledge of bladder dysfunction in anorectal malformations, spinal dysraphism, etc. and the clinical protocol used in these patients also seemed to be useful for understanding the development of voiding dysfunction in patients with neoplasm.

Pheochromocytoma is a catecholamine-producing tumor of the sympathetic nervous system which in 4-14% of the cases may be malignant. The differentiation between benign and malignant phoechromocytomas is very difficult, the presence of metastatic lesions and gross invasion into surrounding tissues are the lonely accettable parameters to confirm malignancy. Since the patients with malignant pheochromocytomas have a very poor survival rate, care must be taken for an early detections and a careful follow up. Three cases of malignant pheochromocytoma are reported. In one of these cases the tumor was a functioning mass; the other two cases presented by a hemorrhagic complication. A careful review of the pertinent literature allows to outline the correct approach to this rare pathology as for the diagnosis and the treatment, also including the actual criteria to establish its malignancy.

Desmoplastic melanoma is an uncommonly encountered variant of malignant melanoma. Three histological subtypes exist: desmoplastic, neurotropic, and neural transforming. Desmoplastic melanoma commonly presents in conjunction with existing melanocytic lesions or as an amelanotic firm nodule. Local recurrences are common. Thirty patients over a 6-year period were treated at our institution for desmoplastic melanoma. All lesions were treated with local excision. Local recurrence occurred in seven patients (23%) and was treated by aggressive re-excision in each instance. Clinical regional metastasis (lymph nodal basins) were detected in two patients (6%). Distant metastasis (lung) developed in two patients (6%). Twenty-three patients (76%) were found to have desmoplastic subtype, whereas five (17%) had neurotropic subtype. Six patients (20%) had associated pigmented melanotic lesions. Average length of follow-up has been 18 months. Overall survival is 96 per cent. Presentations and histologic diagnosis can sometimes be difficult and misleading. Treatment is aggressive local excision with follow-up necessary to detect resectable recurrent lesions.

BACKGROUND/PURPOSE: Gastric resection is an infrequent surgical procedure in childhood. However, the use of the stomach for bladder augmentation and substitution is well documented. Partial gastrectomy performed in gastrocystoplasty (GCP) involves the greater curvature of the stomach, the same area in which gastric pace-maker cells are known to be placed. The aim of this study was to assess, by electrogastrography (EGG), if subtotal gastric resection can alter gastric motility in children submitted to partial gastrectomy for GCP. METHODS: Gastric electrical activity (GEA) was evaluated in 25 children using EGG: 10 patients (4 boys, 6 girls; mean age, 11.6 years) previously submitted to GCP, and 15 normal subjects (12 boys, 3 girls; mean age, 8.62 +/- 2.77 years) as controls. All patients were submitted to cutaneous EGG; recording GEA for 30 minutes before and after a standard test meal. The percentage of 3 cycles per minute (3CPM), bradygastria, tachygastria, DFIC (dominant frequency instability coefficient), DPIC (dominant power instability coefficient), PDP (period dominant power), PDF (period dominant frequency) were recorded and analyzed using Wilcoxon matched-pair test. Data were considered statistically significant if P <.05. RESULTS: Normal subjects as well as operated patients showed a statistically significant difference in bradygastria (P =.05), PDP and PDF (P =.05) percentage, comparing pre versus postprandial period. In the normal group, 3CPM (P =.0012) and DFIC (P =.0008) were statistically different between the pre- and postprandial period. Patients who underwent GCP did not show any statistically significant difference in 3CPM and DFIC pre- and postprandial. CONCLUSIONS: In normal subjects, GEA showed a complete variation after the meal, whereas in operated patients GEA was impaired and only partially modified after the meal. This observation suggests that in patients with gastric resection, adaptation of the stomach to food ingestion is present but incomplete with respect to normal subjects; it can be caused by surgical removal of the pace-maker cells of the greater curvature. For this reason a follow-up analysis of gastric function is recommended for all patients undergoing GCP.

Ten specimens of adrenal cyst resected during the period 1984-1999 were re-examined. Thorough examination of multiple sections and the use of immunohistochemistry allowed to change the recorded diagnosis in 8 cases: three epithelial cysts and five pseudocysts were redefined as endothelial cysts. All 10 cysts were of the endothelial type. A synthetic review of the current knowledge about the pathogenesis, the classification and the clinical aspects of this rare disease is presented.

The Authors report their experience in the treatment of inflammatory aneurysm, on a whole of 355 patients consecutively operated on for abdominal aortic aneurysm. The incidence was 5.6% when relying on clinical aspects; 10.6% when considering the results of microscopy. All patients were operated on through a retroperitoneal approach: early and late results of surgery were not significantly different between the two groups of patients (inflammatory aneurysm 38, atherosclerotic aneurysm 317).

PURPOSE: We evaluated the natural evolution of detrusor voiding contractility in boys who underwent posterior urethral valve ablation using pressure flow analysis, which is a mathematical computerized analysis of pressure flow studies. MATERIALS AND METHODS: Among 30 boys with posterior urethral valves who were being prospectively followed, even if asymptomatic on serial pressure flow studies, 11 were included in our study. These 11 patients had had at least 2 evaluations performed between ages 5 and 15 years, a minimum interval of 4 years between the first and last examination, and all pressure flow studies records available for mathematical analysis of voiding contractility. The first examination had been done at ages 5 to 10 years (average 7 +/- 2.04) and the last one at ages 9 to 15 (12.5 +/- 2.5), including 6 evaluated after puberty. All but 1 patient underwent valve endoscopic resection as a newborn and none received urinary diversion. Voiding symptoms, post-void residual, cystometric bladder capacity and bladder instability were considered. Voiding phase maximal detrusor pressure and flow rate were evaluated and detrusor contractility was calculated by the pressure flow analysis parameters of contraction velocity, detrusor contractile power expressed as watt factor and Schafer's nomogram. Contraction velocity and contractile power factor were considered low if below 2 standard deviations of previously determined normal values. True hypocontractility was diagnosed when at least 2 pressure flow analysis parameters were low. RESULTS: True hypocontractility was detected in 3 of the 11 boys at the first examination and in 8 at the last pressure flow analysis. The remaining 8 and 3 cases of first and last examinations, respectively, were considered to have normal contractility even if 4 of the 8 and 1 of the 3 had 1 low pressure flow analysis parameter (covert hypocontractility). Detrusor contractility worsened in 6 patients, hypocontractility was detected at the first pressure flow analysis in 2, hypocontractility changed to normal in 1 and pressure flow analysis remained normal in 2. Of the 6 boys followed through puberty 5 had hypocontractility, including 3 with cystometric bladder capacity greater than 700 ml., high post-void residual and strained voiding. Of the 11 patients 8 had detrusor instability, including 7 with urge symptoms, at first evaluation which was not found at last examination. CONCLUSIONS: Pressure flow analysis extensively used in men has been confirmed as a useful tool to assess voiding contractility in children. The majority of boys with posterior urethral valves have progressive impairment of detrusor contractility at voiding many years after relief of obstruction. The pattern of hypocontractility, which is detected early on pressure flow analysis, follows a prolonged phase of instability in many cases and leads to an over distended bladder in most patients followed after puberty. Questions arise if this evolution may be prevented by early (pharmacological or rehabilitative) treatment and if it is partially determined by extensive use of drugs acting against unstable detrusor contractions.

The authors report a case of giant cavernous hemangioma of the liver, almost entirely extrahepatic, bulging from the inferior surface of the right lobe into the abdomen, treated surgically on account of worsening symptoms referable to continuing growth. A thorough search of the literature allows a critical review of the surgical indication in this benign pathology, rarely complicated by significant clinical events. Surgery is indicated, in lack of relevant complications, only when significant symptoms, continuing or worsening, are undoubtedly referable to the presence of the angioma.

PURPOSE: To establish whether infants with vesico-ureteral reflux (VUR) have bladder dysfunction, with difference in gender, age at presentation and severity. PATIENTS AND METHODS: 37 infants (24 male and 13 female) aged 2 to 24 months with II degrees to V degrees degree VUR underwent cystometry. Of those, 10 underwent natural filling cystometry. We considered: instability and maximal voiding detrusor pressure (VDP) to be "high" when it exceeded 90 cm H2O. We defined hypercontractility as high VDP and/or instability. RESULTS: The prevalence of hypercontractility was 75% (18/24) in male and 46% (6/13) in female infants (p<0.004). High VDP was found in 50% (12/24) of male and 7% (1/13) of female patients (p < 0.001); no significant difference was found between male (25%) and female ones (38%) with instability alone. The mean VDP was significantly higher in male than in female infants (p < 0.001), in patients < 1 year of age than in older ones (p<0.001) and in severe than in moderate reflux (p<0.006). The mean voiding detrusor pressure of male infants was higher in severe (108+/-46cm H2O) and bilateral (101.3+/-44cm H2O) than in moderate (76+/-24 cm H2O) and unilateral (73.7+/-24 cm H2O) and in infants < 1 year of age (101.7+/-42 cm H2O) than in older ones (70.2+/-21 cm H2O). Natural filling cystometry confirmed the results of standard urodynamic studies. CONCLUSIONS: Bladder dysfunction is confirmed also in infants with reflux, particularly in male younger patients, and it differs in gender. The pathogenesis of congenital reflux is not always a feature of malformation of the vesico-ureteral junction; therefore, patients with bladder dysfunction must be identified early.

We report a case of a 35 year-old woman with a large malignant sessile tubulo-villous polyp of the proximal end of a dolico-sigmoid colon causing intussusception and transanal prolapsing. The diagnosis presented some difficulties being the intussusception intermittent. The clinical feature had been initially misdiagnosed for a very large bleeding polyp (5 cm in size), protruding out of the anus with a long pedicle in the rectum. The histology of multiple bioptic samples of the lesion revealed malignancy. Conventional radiologic studies (plain x-rays, barium enema) after metal clips had been placed on the head of the polyp before it rose up the colon, led to the correct diagnosis without, nevertheless, documenting intussusception. An elective surgical resection of the dolico-sigmoid colon allowed the correct diagnosis and the curative treatment of the colonic intussusception and the malignancy.

New treatments for chronic wounds require carefully performed clinical trials with significant endpoints. Total wound closure is the only endpoint currently accepted by the Food and Drug Administration. This study describes a scale that measures ease of wound closure and applies it to a four-arm prospectively randomized, blinded pressure ulcer trial of recombinant human platelet-derived growth factor-BB. Following validation of interrater reliability, 83 evaluable subjects' photographs were given a weekly ease of closure score by four raters blinded to treatment. The change of ease of closure score was correlated with the change of wound area and volume. Each ease of closure score was given a procedural cost. Results showed ease of closure did not directly correlate with either wound area or volume, suggesting that it was measuring additional information. The mean change in ease of closure score was 6 for subjects treated with 100 microg recombinant human platelet-derived growth factor-BB daily; 5 for those treated with 300 microg growth factor daily or 100 microg recombinant human platelet-derived growth factor-BB bid; and 4 for those treated with placebo. The cost savings ranged from $7200 for the group receiving 100 microg recombinant human platelet-derived growth factor-BB daily to $6300 for the controls. Outcomes in all 4 groups were significantly improved from their starting evaluation (p < 0.001). Based on this study, ease of closure is a verifiable endpoint that can be related to cost efficiency and may be a measure of efficacy.

OBJECTIVE: To verify, in a retrospective analysis, the effectiveness of endoscopic treatment (collagen injection) in children with neurogenic bladder and neurogenic urinary incontinence. PATIENTS AND METHODS: From January 1992 to March 1997, 36 endoscopic collagen injections were performed to treat neurogenic urinary incontinence in 23 patients (mean age 10.9 years, range 6-17 at the time of the first procedure) selected on the basis of clinical status and the patient's motivation. Nineteen patients were affected by myelomeningocele and four had an occult spinal dysraphism. All patients underwent a preoperative cystometric urodynamic evaluation (without urethral pressure measurement) which showed detrusor areflexia in 12, normal reflexia in one and hyper-reflexia in 10 patients. Bladder compliance was considered good (> or =20 cmH2O) in 13 patients and low (10-20 cmH2O) in 10, four of whom had detrusor areflexia. Twenty-one children emptied their bladder by intermittent clean catheterization. The mean (range) follow-up was 19.2 (6-54) months. Twenty (group A) and 16 (group B) procedures, performed early and late in the series, were analysed separately to determine any increase in effectiveness with surgical experience. The evaluation criteria were; the increase in the 'dry' interval (between catheterizations) before and after treatment/s (delta dry); the patient's and parent's satisfaction; the number of endoscopic procedures and quantity of injected materials. RESULTS: There was an improvement (dryness of at least 2 h: delta dry of 1 h) in 13 of 23 patients after 1-3 (mean 1.5) procedures; 10 patients had a 0.2 h increase in delta dry after 1-3 injections and none was satisfied. There was no difference in the delta dry (0.9 vs. 0.7 h) between groups A and B, and/or the patient's/parent's satisfaction. Success rates differed with urodynamic patterns; seven of 10 patients showing no improvement had hyper-reflexia and three of the remaining 12 with areflexia had hypocompliant bladders, while nine of the 13 showing improvement had an areflexic detrusor and low-pressure bladders. CONCLUSION: The efficacy of the treatment depends largely on the urodynamic selection of patients (mainly those with detrusor areflexia and good compliance). The outcome may be improved further by increasing the quantity of injected material and with a longer follow-up, performing the procedure again if advisable. A close postoperative clinical (pad test) and personal observation is necessary to evaluate the outcome and thus optimize the strategy of treatment.
