A series of 91 cases of unilateral obstruction of the pelviureteric junction is reviewed. Primary nephrectomy was performed in 13 cases (14%) because of severe hydronephrosis and renal function less than 10% that of the normal kidney. Pyeloplasty was performed according to Anderson-Hynes in 74 cases and with a Culp-De Weerd flap in four cases. Nephrostomy was performed concomitantly with the pyeloplasty in 14 cases. The parenchymal function was normal before pyeloplasty in 78% of the 78 kidneys, though the drainage function was severely impaired in 76 of the kidneys and moderately impaired in two. Urine cultures were positive before pyeloplasty in two patients, and 13 of the treated kidneys contained calculi. Follow-up examination was performed 5 to 12 years (mean 8.5 years) after pyeloplasty in all 78 patients. Of the 17 kidneys with preoperatively impaired parenchymal function, 12 (71%) showed improvement. The drainage function was improved in 68 (91%) of the 75 studied kidneys. Persistently impaired drainage function after pyeloplasty was found only in kidneys with infection secondary to retrograde passage of a ureteral catheter for treatment of postoperative urinary leakage. Urinary infection occurred in 11 of the 33 cases with such leakage. Retrograde ureteral catheterization thus favoured the occurrence of urinary infection. Its importance as a risk factor for severe infection was shown by the necessity for secondary nephrectomy in three cases. Since nephrostomy tended to reduce the incidence of urinary leakage, and thereby the need for indwelling ureteral catheter, and since nephrostomy as such was not associated with urinary infection, we recommend its use in the management of idiopathic hydronephrosis. 相似文献

Giant hydronephrosis due to uretero–pelvic junction obstruction (UPJO) is rare and usually the treatment is nephrectomy. When
renal salvage is required, reconstruction of the UPJ alone is usually inadequate to improve drainage from the pelvicalyceal
system. Various open surgical techniques have been described to improve gravity-assisted drainage from the giant hydronephrotic
kidney. We describe, for the first time, a complete laparoscopic approach for pyeloplasty combined with nephroplication and
nephropexy. 相似文献

Pelvi-ureteric junction obstruction in children: the role of urinary transforming growth factor-beta and epidermal growth factor 总被引:1,自引:0,他引:1
OBJECTIVES: To investigate the role of transforming growth factor beta(1) (TGF-beta(1)) and epidermal growth factor (EGF) in voided urine for the diagnosis and follow-up of children with pelvi-ureteric junction obstruction (PUJO). PATIENTS, SUBJECTS AND METHODS: The study included 35 children with unilateral PUJO who had a pyeloplasty, and 30 healthy control children. Urine samples were obtained from the bladders of patients before surgery, and as voided samples at 1, 2, 3, 6, 9 and 12 months after surgery. Bladder urine samples were also collected from all 30 children in the control group. TGF-beta(1) and EGF were then measured in all the urine samples. RESULTS: The level of bladder TGF-beta(1) before surgery in the patients was significantly higher than that in the healthy control group. A threshold of 190 pg/mg creatinine gave a sensitivity of 100%, a specificity of 80%, a positive predictive value of 85.4%, negative predictive value of 100% and an overall accuracy of 90.8%. Compared with the value before surgery, urinary TGF-beta(1) was significantly lower at 1 year after pyeloplasty. There was no significant difference between the level of EGF before surgery in the patients and that in the control group, and no significant difference in the level of EGF before and after surgery over the follow-up. CONCLUSION: We do not recommend using EGF levels in voided urine in the routine diagnosis of children with hydronephrosis. The urinary level of TGF-beta(1) is a useful noninvasive tool for the long-term follow-up of children with PUJO treated by pyeloplasty. Further studies with various controls are required to confirm the diagnostic accuracy of TGF-beta(1) in children with PUJO. 相似文献

OBJECTIVE: To determine the incidence and efficacy of treatment for pelvi-ureteric junction obstruction (PUJO, the most common cause of hydronephrosis in the fetal kidney) in duplicated systems. PATIENTS AND METHODS: We retrospectively assessed patients with PUJO in a duplex collecting system, reviewing each case for age, sex, anatomy, presenting symptoms and type of management. RESULTS: From 1994 to 2004, 1413 patients were identified to have hydronephrosis; 243 of them had pyeloplasty for PUJO, and five (2%) involved the lower pole of a duplicated collecting system. In two of the patients the presentation was prenatal hydronephrosis (mean age at diagnosis 6 weeks) and the remainder presented with flank pain and pyelonephritis (mean age 5 years); all were boys. There was only one incomplete duplication (Y type). Four patients had a dismembered pyeloplasty and one a ureteric calycostomy. Vesico-ureteric reflux was present in three patients and two required common sheath reimplantation. On a radioisotope scan during the follow-up (mean 12 months) the five patients showed an improvement and no evidence of functional obstruction. CONCLUSION: The incidence of PUJO in duplicated systems was 2%; treatment should be individualized and requires a careful preoperative evaluation. This anomaly appears to be more common in boys and in completely duplicated systems. 相似文献

OBJECTIVE: It is well described that unilateral pelviureteric junction obstruction (PUJO) is a benign condition, because the dilatation resolves spontaneously and the function does not decrease in most of the kidneys. However, there is exceptional PUJO that requires emergent treatment in neonatal periods. The aim of this article is to report the urological emergency and management in neonates with PUJO. MATERIALS AND METHODS: Nine children (seven boys and two girls) with PUJO who underwent neonatal emergent treatment during the last 13 years were reviewed. Renal function was evaluated according to decay curve of serum creatinine (SCr) levels corresponding to gestational age (GA) at delivery. Physical examination, ultrasonographic monitoring, and chest and abdominal plain radiographs were repeated in each neonate. RESULTS: Eight patients were detected prenatally. In five patients, multicystic dysplastic kidney (MCDK) was demonstrated on the contralateral side. Three patients underwent percutaneous puncture of fetal hydronephrosis. Decrease of amniotic fluid was evident in three fetuses. Indications for emergent treatment included mass effect from hydronephrosis in three patients, renal dysfunction in five, and severe urinary tract infection in one. During neonatal periods, a percutaneous nephrostomy tube was placed in seven, and open nephrostomy in one with anorectal malformation. Repeated punctures of the dilated renal pelvis were done in one patient. Renal function after pyeloplasty was stable in eight patients, while it was moderately decreased in one who was associated with oligohydramnios in utero. CONCLUSION: Indications for emergent treatment in neonates with PUJO included mass effect from giant hydronephrosis, renal dysfunction and severe urinary tract infection. At birth, respiratory and circulatory conditions must first be stabilized. In neonates with hydronephrosis of the solitary kidney or severe bilateral PUJO, serial SCr should be monitored to evaluate renal function. Decrease of amniotic fluid suggested renal functional compromise that would not recover after urological management. 相似文献

PURPOSE: Methods of stenting after laparoscopic pyeloplasty have included indwelling Double-J stents and percutaneous nephrostomy tubes. The disadvantages of these methods are that they necessitate a second surgery for stent removal or require an external drainage bag. To circumvent these issues, the tolerance, safety and outcomes of using a Double-J ureteral stent with a dangler, permitting early office removal, was investigated in a series of pediatric laparoscopic pyeloplasties. MATERIALS AND METHODS: Medical records from a consecutive series of pediatric patients undergoing transperitoneal laparoscopic pyeloplasties were reviewed. Indications for surgery included ipsilateral flank pain with severe hydronephrosis (12 patients), recurrent pyelonephritis with severe hydronephrosis (2), and hematuria and flank pain (6). All patients were discharged home within 24 to 48 hours of the procedure with prophylactic oral antibiotics. The stent was removed by postoperative day 18 during a followup office visit. Patient tolerance of the indwelling stent, outpatient removal and success of pyeloplasty were assessed. RESULTS: A total of 20 patients underwent transperitoneal laparoscopic pyeloplasty by 1 surgeon (LAB) between 2001 and 2005. All patients underwent cystoscopy and retrograde Double-J ureteral stent placement before pyeloplasty under the same anesthesia. Mean patient age at operation was 11.3 years (median 11.3, range 4.6 to 17.2). Stents were left indwelling for a mean of 10.3 days (median 10, range 7 to 18). All patients tolerated the Double-J stent well, with 2 requiring anticholinergic therapy for mild urgency symptoms and 1 demonstrating urinary tract infection. All patients tolerated outpatient stent removal via the dangler at the office without discomfort. One patient was lost to followup. At a mean followup of 1.04 years (range 0.1 to 2.88) 17 of 19 patients (89%) had resolution of flank pain/urinary tract infections, with sonographic improvement in hydronephrosis with or without endoscopic intervention. Six patients (30%) had flank pain with or without continuous hydronephrosis and required re-stenting, and 3 also required balloon dilation. Of these 6 patients 2 (10%) had recurrent ureteropelvic junction obstruction and required open pyeloplasty. All patients are now clinically and radiologically unobstructed and asymptomatic. CONCLUSIONS: Pediatric transperitoneal laparoscopic pyeloplasty with indwelling Double-J ureteral stent with a dangler is successful and the stent is well tolerated. Whether the duration of ureteral stenting affects the surgical success will require further controlled long-term studies. 相似文献
