Nonunion of longbones is a significant consequence in treating fractures, which is not easy to treat. Thes reviewed the basic knowledge and main progress regarding the cause, pathogenesis, pathophysiology of nonunion, and the methods that may be applied to the treatment of nonunion especially those non-operative one.

Objective To evaluate the urodynamic outcome after bladder augmentation using double de-epithelialized segment of small intestine lined with urothelium. Methods Twenty-five children with neurogenical bladder (age range,4 to 14 years;16 males and 9 females) underwent bladder augmentation using de-epithelialized segment of small intestine lined with urothelium.Pre- and post-operative voiding cystoureterography,urodynamic and clinical evaluation were performed on them.Of them 21 cases were followed up for 6 to 24 months after operation. Results Bladder volume was increased from pre-operative (142.14?45.88)ml to post-operative (242.62?60.04) ml,compliance from (3.26?1.57) ml/cmH 2O (1 cmH 2O=0.098 kPa) to(8.10?3.00)ml/cmH 2O,and maximum urine flow rate from (3.00?1.00) ml/s to (7.60?2.90)ml/s,respectively(P

Objective To investigate the clinical features of anuria caused by pediatric congenital bilateral ureteral stenotic obstruction,and to improve the diagnosis and treatment of the disease.Methods This series included 7 infants(2 males and 5 females;age range,35-57 d) with congenital bilateral ureteral stenotic obstruction.The clinical presentations were characterized by sudden anuria or oliguria.B-ultrasound,cystography and puncture pyelography were performed in all of them,and magnetic resonance urography(MRU) in 3.Based on the definite diagnosis,resection of stenotic segment of the ureter or ureteral implantation was performed on them.Results The diagnosis was confirmed by puncture pyelography in all of the 7 cases.Six cases underwent phase I surgery and recovered.No ureteral stenosis and cystoureteral reflux occurred during a follow-up of 2-4 years.The renal function was normalized in them.One case had stenosis recurrence due to scar formation,and was cured by the second operation.Conclusions Anuria caused by pediatric congenital bilateral ureteral stenosis should be diagnosed and treated as early as possible.Definite diagnosis can be established by puncture pyelography and MRU.Resection of the obstructive segment of the ureter,protection of renal function,and ureteral implantation are the main therapies.
