ABSTRACT
Desmoid-type fibromatosis is a rare benign tumor with invasive growth, which can occur in all parts of the body, mostly in the abdominal wall, and also in the abdomen and skeletal muscle. This paper reports a case of right ureteral stenosis caused by pelvic desmoid-type fibromatosis. Pelvic tumor resection, ileocecal resection and ureterovesical replantation were performed. The patients were followed up for 18 months without local recurrence and distant metastasis.
ABSTRACT
Aggressive fibromatosis(AF)is a rare soft tissue tumor clinically that presents with local aggressive growth, are prone to relapse, but rarely metastasize to distant sites. It occurs in the limbs, trunk, mesentery, etc., but is rare in the pelvis or around the urinary system. This article reported a case of ureteral stenosis secondary to pelvic AF. The surgical treatment was effective.
ABSTRACT
A 67-year-old male renal transplant patient presented with a right inguinal bulging mass, and was diagnosed with a right indirect inguinal hernia. The day following inguinal herniorrhaphy, serum creatinine became elevated. The patient was oliguric and had abdominal pain on the first day after inguinal herniorrhaphy with a mesh. We diagnosed him with acute renal failure and subsequently performed acute hemodialysis. The kidney computed tomography showed hydronephroureter, with distal ureter obstruction. With urgent percutaneous nephrostomy, we were able to relieve the obstructive uropathy with distal ureteral stenosis. Subsequently, hernia repair was performed with removal of the mesh, followed by the antegrade ureteral stent insertion. Renal function was recovered after ureteral stent insertion. This case shows that acute renal failure can occur due to ureteral obstruction, complicated by an inguinal hernia repair, and this can be successfully treated with percutaneous nephrostomy and inguinal hernia repair with mesh removal.

ObjectiveTo analyze the technique and clinical effect of percutaneous nephrolithotomy combined with endoscopic balloon dilation in the treatment of upper ureterostenosis with recurrent renal calculi. MethodsFrom June 2008 to June 2011,18 ureteral stenosis patients with the history of ureteral open surgery,postoperative residual or recurrent kidney stones were treated.There were 8 males and 10 females with the age of 27 -48 years.Fourteen cases were with hydronephrosis of 2 -4 cm,3 cases were with hydronephrosis of 5 -6 cm and 1 case was with hydronephrosis ＞6 cm.Subsequent stone size ＜ 1 cm was found in 15 cases,1 -3 cm in 3 cases,＞3 cm in 1 case.All patients were treated with percutaneous nephrolithotomy ultrasonic lithotripsy combined with balloon dilatation.The stone clearance rate,hydronephrosis changes,complications and IVP situation before and after surgery were analyzed.ResultsAll the 18 cases were completed surgery successfully.There was 1 (6％) case with renal hemorrhage 3 days after the surgery and controlled with DSA hemostasis.There was 1 case accepted adjusting double-J tube by ureteroscopy.Sixteen (89％) patient's stones were completed removed.One case with residual calyceal stones size ＜5 mm was not further treated.There was 1 case treated with nephrectomy because of renal stone with infection.The patients were followed up for 6 to 36 months.Fourteen cases with hydmnephrosis improved significantly; 3 cases with no significant changes but improved following balloon dilation.All patients achieved significant improvement in imaging study comparing of preoperative and postoperative data.ConclusionThe use of percutaneous nephrolithotomy combined with endoscopic balloon dilation is a safe and efffective treatment option in the treatment of kidney stones with ureteral stenosis.

Objective To summarize the experience of diagnosis and surgical treatment of long distance ureteral stenosis after kidney transplantation. Methods Eleven cases of ureteral stenosis following renal transplantation were analyzed. Ureteral stenosis happened between 2-6 months after transplantation. The clinical manifestations were as follows: serum creatinine and weight elevated,urine decreased, graft area swelling. All cases were diagnosed using ultrasound, MRU or CTU. The ureteral obstruction length was 3-7 cm. In 5 patients a Boari flap technique was used, and the native ureter for pyelo-ureterostomy was used in 2 patients. Four patients were subjected to surgical operation using the native ureter for uretero-ureterostomy. Results All of the surgical treatments were successful and no operation-related complications occurred. The operation time was 2. 5 to 4 h.After reconstruction of ureter-bladder anastomosis, the urine was increased, the serum creatinine decreased to 75-156μmol/L, and uronephrosis disappeared or alleviated. The follow-up lasting 8 to 62 months showed no recurrence in all the cases. Conclusion For such cases, ultrasound should be routinely used for the possibility of stenosis. CTU or MRU is important to know the obstruction length and position. For the patients with long distance ureteral stenosis after kidney transplantation,surgical correction is the first choice.
ABSTRACT
La obstrucción ureteral post trasplante renal es una complicación tardía del trasplante y la incidencia actual ha disminuido a un 5-10 por ciento en la literatura. Reportamos el caso y describimos la técnica quirúrgica, de una estenosis ureteral post trasplante renal en una niña, resuelta en forma exitosa con una anastomosis de la pelvis renal del injerto al uréter nativo. La estenosis ureteral post trasplante renal en niños es poco frecuente, puede ser manejada en forma exitosa con esta técnica quirúrgica.
Ureteral obstruction is a late complication in renal transplant. The current incidence has lowered to 5- 10 percent in the literature. We report a case of ureteral stenosis post renal transplant in a 12 years old girl. We describe the surgical technique used to correct this complication an anastomosis between the native ureter and the renal pelvis of the graft. Post renal transplant ureteral stenosis is an uncommon complication in children, and can be successfully managed using this surgical procedure.

Objective:To analyze the cause and treatment of ureteral stenosis in the early stage after kidney transplantation.Methods:250 cases of the kidney transplantation since 1993 to 2007 were collected and analyzed, including 141 men and 109 women,240 cadaveric transplantations and 10 living dononr transplantations. Results:In 8 cases(3.2%) ureteral stenosis occurred in the early stage following the renal transplantation;including hematoma compression(2cases);stenosis of ureter- bladder stoma(2cases);ureter torsion(1case);transplantal kidney torsion(1case);stomal leak(1case) and hydropsia of spermatic cord(1case). 7 cases required another surgical operation to remove the obstruction and the renal function recovered in these cases. Conclusion:The ureteral stenosis in the early stage of kidney transplantation was mostly contributed to the surgical reasons such as mis-perfamance. The occurance rate of ureteral stenosis should be reduced if each one step of the kidney transplantation is carefully performed. The open surgical managemen is a direct and effective method to remove the obstruction.
