ABSTRACT
Objective:To explore the clinical characteristics and treatment regimens of adrenal incidentaloma (AI) in children.Methods:Clinical data of 38 children with AI treated in the Department of Urology, Children′s Hospital of Nanjing Medical University from December 2016 to October 2021 were retrospectively analyzed.A total of 38 children were divided into neonatal group and non-neonatal group according to their age at first diagnosis.The neonatal group had 7 males and 9 females patients, of whom 7 cases were detected with AI during prenatal examinations, 9 cases were diagnosed postnatally.Four children in neonatal group had AI in the left adrenal gland and 12 cases in the right, with the maximum diameter of tumor (MDT) ranging from 16-48 mm.In the non-neonatal group, there were 14 males and 8 females patients aged 7 months and 1 day to 12 years and 1 month, and the MDT was 29-131 mm.Paired t test was used to compare the age and MDT of benign and malignant tumors. Results:In the neonatal group, 3 patients were surgically treated, with 2 cases and 1 case of neuroblastoma and teratoma confirmed by postoperative histology, respectively.The remaining 13 patients in the neonatal group were followed up for 1-31 months, with 8 cases and 5 cases of complete remission and significantly decreased tumor volume, respectively.In the non-neonatal group, there were 3, 9 and 10 patients received open biopsy, laparoscopic adrenalectomy, and open adrenalectomy, respectively.Of these 22 surgically treated cases, 8 cases had a benign lesion, including ganglioneuroma ( n=4), adrenocortical adenoma ( n=1), adrenal cyst ( n=1), teratoma ( n=1), and pheochromocytoma ( n=1); while 14 cases had a malignant lesion, including neuroblastoma ( n=8), ganglioneuroblastoma ( n=5), and adrenocortical carcinoma ( n=1). The mean age of patients with malignant tumors was significantly younger than those with benign tumors[(38.94±35.44) months vs.(95.89±41.43) months, t=3.63, P=0.001]. The mean MDT in malignant tumors was significantly longer than that of benign tumors[(64.43±25.20) mm vs.(41.44±15.66) mm, t=2.45, P=0.023]. Conclusions:AI in children has a high risk of malignancy.Therefore, more detailed examinations are needed to detect tumor markers and endocrinological parameters, and imaging tests such as non-contrast and CT examination should be performed as early as possible.AI in children is predominantly neuroblastic tumors.For non-neonatal patients, surgery should be performed as early as possible.For AI found in the neonatal period and prenatal examination, expectant management is feasible if the tumor is relatively small and limited to the adrenal gland without distant metastases.
ABSTRACT
Objective@#To study the therapeutic effect of laparoscopic ureteral end-to-side anastomosis at pelvic level for duplicate ureteral malformation.@*Methods@#Clinical data of 10 children with unilateral ureteral duplication, who received laparoscopic ureteral end-to-side anastomosis at pelvic level at Department of Urology, Affiliated Children′s Hospital of Nanjing Medical University from September 2016 to November 2017 were reviewed.There were 6 boys and 4 girls with an average age of 13.9 months(1 month and 21 days to 3 years and 9 months). Ultrasonography, intravenous pyelography and magnetic resonance urography were performed before surgery.There were 6 cases of duplication with hydronephrosis in the upper moiety.

ABSTRACT
Objective@#To explore the application of penile base staggered flap in the operation of severe hypospadias with penoscrotal transposition.@*Methods@#Twenty-three cases with severe hypospadias with penoscrotal transposition were corrected by urethroplasty and staggered flap plasty in our department from May 2013 to June 2016. After urethroplasty, the skin at the junction of the penile base and scrotum was transversely cut by 1.5-2.0 cm, and then sutured with Z-plasty to reconstruct the angle of the penis and scrotum.@*Results@#After the operation, infection and cracking at the suture of the staggered flap occurred in one child and was cured after dressing change and symptomatic treatment. Two cases suffered from urine leakage at the suture of the staggered flap. One of the cases realized self-healing and the other received a repair operation for urinary fistula. Three children suffered coronary sulcus fistula and was cured by urethroplasty. All the patients were followed up from 10 to 30 months with normal penis scrotal position and satisfactory appearance.@*Conclusions@#The application of penile base staggered flap can be used for severe hypospadias in one stage with penoscrotal transposition surgery. It is a simple and satisfactory method for the treatment of hypospadias with penoscrotal transposition.
ABSTRACT
Objective To analyze the prognostic factors of adrenal tumor in children under 12 years of age. Methods A total of 90 children with 97 adrenal tumors admitted from June 2006 to August 2017 were selected in Children's Hospital of Nanjing Medical University.The age distribution,tumor type,biochemistry and tumor indicators, treatment,stage classification and prognosis were analyzed.Results There were 46 males and 44 females in 90 cases. Ages ranged from 4 days to 11 years and 1 month,with an average of (38.1 ± 31.3)months.The main clinical mani-festations were abdominal mass,fever and abdominal pain.Eighty cases (82.5%)underwent surgery,while 17 cases (17. 5%)did not.Open resection was performed in 48 cases,open partial resection in 11 cases,laparoscopic surgery in 10 cases,and just biopsy in 11 cases.The pathological examination showed 43 cases with neuroblastoma,13 cases with ganglioneuroblastoma,8 cases with ganglioneuroma,5 cases with adrenocortical carcinoma,3 cases with teratoma,1 case with pheochromocytoma,1 case with malignant rhabdoid tumor.Statistical analysis revealed that neuron－specific eno-lase(NSE)value of neuroblastoma and lactate dehydrogenase(LDH)value of cortical cancer increased significantly. The age was correlated with tumor stage,and patients had older age on stage Ⅳ.Complete resection in surgery was correlated with the stage of the tumor,as tumor in lower tumor stage seemed easier to be completely removed.Fifty－three cases (58.9%)were followed up for 2 months up to 11 years and 4 months.Forty－four cases survived and 9 ca-ses died.Higher tumor stage predicated worse prognosis.Conclusions Adrenal gland tumors need early diagnosis and active treatment.Earlier onset of age,complete surgical resection with patients have better prognosis.Complete resection of the disease was a key factor in the prognosis.
ABSTRACT
Objective To discuss the efficacy of laparoscopic ureteroureterostomy for upper pole hydronephro-sis and ureteral dilatation in children with complete duplex kidney.Methods The clinical data of 14 patients (15 units in total)who underwent laparoscopic ureteroureterostomy from April 2016 to October 2017 were retrospectively analyzed. Nine out of 14 cases had repeated urinary tract infections(UTI)and other symptoms[6 cases in group A:patients without vesicoureteral reflux(VUR)but presenting urinary tract infection (UTI)symptoms,3 cases in group C:patients diagnosed with VUR];5 cases of asymptomatic patients were selected as group B.All the 14 cases had upper pole hydronephrosis and ureteral dilatation.Preoperative examinations included ultrosonograpy,urinary magnetic resonance urography(MRU), intravenous pyelography (IVP),voiding cystourethrogram(VCUG),and nuclear renal scanning.It was found that 4 cases had ureterocele;3 cases had recurrent cystoureteral reflux (group C)before operation,and 1 case had cystoureteral re-fluxed after replantation.Results Laparoscopic surgery was successful in all of 14 children.None of them were shifted to open surgery because of abdominal viscera injury bleeding.The operation duration was 85－140 min.The average posto-perative hospital stay was 5.58 days.There was neither urinary anastomotic leakage nor UTI.Fourteen cases were followed up and the postoperative follow－up period was 7－23 months.No cases developed urinary tract infection except 2 cases with vescioureteral reflux.Ultrasound examination showed that the upper renal parenchyma of 5 children was thicker,ul-trasonography showed that upper pole hydronephrosis was better and ureteroceles were smaller.There was no complication such as lower pole hydronephrosis.The symptoms of urinary tract infection disappeared after operation.Conclusions Laparoscopic ureteroureterostomy can treat renal duplication with less trauma,and it is safe and effective.It can be one of therapeutic regimen to treat low－functional upper pole hydronephrosis and ureteral dilatation in renal duplication.Howe-ver,this procedure cannot be used for vescoureteral reflux cases because of high rate of stump infection.
ABSTRACT
Objective To explore the diagnosis,treatment options and outcomes of patients with ureteropelvic junction obstruction(UPJO)and ureterovesical junction obstruction(UVJO). Methods Clinical records of 12 children with UPJO and UVJO who received treatment in Children′s Hospital of Nanjing Medical University from April 2008 to December 2015 were reviewed. Presentations included prenatal hydronephrosis and symptoms caused by urinary tract in-fections. Ultrasonography,intravenous pyelography,magnetic resonance imaging and renography were performed before surgery. Results Four patients underwent nephrostomy,followed by pyeloplasty and eventually,ureteroneocystostomy. Five patients underwent heterochronic pyeloplasty plus ureteroneocystostomy. Two patients received pyeloplasty only. And another patient underwent heterochronic nephrostomy plus ureteroneocystostomy. The 12 patients received a 2. 0 months to 2. 5 years′ follow - up. Recurrent urinary tract infection and abdominal pain were relieved after the treatment. Ultrasonography showed hydronephrosis reduced obviously after the surgery. Conclusions UVJO patients with unparallel hydronephrosis should be considered with the coexistence of UPJO. Retrograde pyelography(RPG)is recommended for the diagnosis. And the treatment includes both pyeloplasty and ureteroneocystostomy. The patients diagnosed with UPJO should be first managed with pyeloplasty or nephrostomy instead of RPG. Subsequently anterograde pyelography can be performed to decide if the patients need additional ureteroneocystostomy.
ABSTRACT
Objective To analyze the clinical characteristics and treatment of post - renal acute renal failure (ARF)induced by Ceftriaxone in children. Methods The clinical data of 7 cases of post - renal acute renal failure in children from June 2012 to June 2014 induced by Ceftriaxone were analyzed. According to the changes in urine volume, serum creatinine,blood urea nitrogen and serum potassium level,liquid therapy,retrograde ureteral catheterization (RUC)and peritoneal dialysis was performed by step sequential therapy respectively. Results Seven cases were given intravenous Ceftriaxone under the fluid loss state. Abdominal pain,sudden anuria or oliguria appeared in the children af-ter 2. 6 d on the average,B ultrasonography and CT scanning showed multiple calculus in the bilateral renal pelvis and ureteral calculi. Blood BUN was 15. 2 - 37. 9 mmol/ L[(23. 3 ± 8. 6)mmol/ L],and blood Cr was 180 - 636 μmol/ L [(378. 9 ± 148. 4)μmol/ L]. These indicators met the diagnostic criteria for acute renal failure. In 7 cases,2 cases (28. 6% )received fluid therapy of sodium bicarbonate alkalization and anisodamine spasmolytic,4 cases(57. 1% )re-ceived fluid therapy and RUC,and 1 case(14. 3% )underwent fluid therapy and RUC and peritoneal dialysis. All of 7 cases(100% )were alive. In the average 4. 4 days renal function of 7 cases was returned to normal,and urine volume and electrolyte were also restored. Conclusions Step sequential therapy including fluid therapy,RUC and peritoneal dialysis is effective with post - renal ARF in children induced by Ceftriaxone.
ABSTRACT
Children with voiding dysfunction is common in clinic.The traditional conservative treatment of voiding dysfunction in children can obtain good therapeutic effect,but there are some children with voiding dysfunction refractory to conservative treatment.Electrical stimulation provides an effective new treatment for children with voiding dysfunction refractory to traditional conservative treatment.This paper describes the application of electrical stimulation in children with voiding dysfunction.It maybe provide the pediatric urologists with a new idea about the treatment for voiding dysfunction.
ABSTRACT
Objective To summerize the clinical experience of 23 cases of carotid cavernous fistula(CCF) and discuss the treatment strategy. Methods Retrospectively analyzed 23 patients(11 males and 12 females) of CCF,including 14 patients with Barrow type A,1 with type B,1 with type C and 7 with type D. Results Vascular approach for embolization was undertaken in 20 cases by transarterial access and 2 via venous route while 1 case was given up. Among them,9 cases obtained complete occlusion by simple balloon embolization and 5 were treated by direct occlusion of internal carotid artery. Another 5 cases used NBCA glue for the occlusion,1 case was embolized by gelatin-sponge particulates combined with compression of carotid artery,2 cases were treated by coil embolization of cavernous sinus and 1 case was only managed by carotid compression maneuver. We achieved satisfactory clinical results with 21 patients cured and 2 patients improved. Conclusion Complexity and refractory are the characteristic of CCF,and endovascular treatment should be the major choice of treatment. (J Intervent Radiol,2006,15: 323-326)
