Application of single-wire suspension in laparoscopic pyeloplasty in children
To investigate the clinical value of single-wire suspension in laparoscopic pyeloplasty in children.
Methods
:
2
A total of 14 cases of laparoscopic pyeloplasty in children were collected from Huai'an Maternal and Child Health Care Hospital from January 2019 to June 2021
including 9 males and 5 females. Age ranged from 2 months and 13 days to 8 years and 7 months
with mean age of 2 years and 9 months. There were 11 cases on the left and 3 cases on the right. Preoperative routine examination of all the children showed no obvious abnormalities
and the diagnosis was confirmed by intravenous urography (IVU) and magnetic resonance urography (MRU) . During the operation
the renal pelvis and ureter were cut out by single-wire suspension method under laparoscope
and then fine pyelo-ureter tension-free anastomosis was performed. Combined with the results of urine examination and ultrasound examination
individualized follow-up plan was formulated.
Results
:
2
All the 14 cases had successful operation
and all underwent primary anastomosis. No case was transferred and opened
and no blood transfusion occurred. The operation time was 110-155 min
and the average operation time was 140 min. Intraoperative bleeding of 4-8 mL mainly occurred during the cutting of the renal pelvis and ureter. Abdominal drainage tube was removed 3-7 days after surgery
and catheter was removed 7-20 days after surgery. After 6-8 weeks
the double J tubes were removed under cystoscopy. After 6-12 months of follow-up
14 patients showed progressive reduction of anterior and posterior renal pelvis diameter and gradual retraction of renal pelvis and calyces. No anastomotic stenosis
urine extravasation
recurrent hydronephrosis
urinary tract infection and other complications.
Conclusion
:
2
Laparoscopic pyeloplasty in children by single-wire suspension method is convenient for accurate anastomosis of renal pelvis and ureter. It is a simple
