1. Thirty-two per cent of cases examined by I.V.P. showed evidence of disease (20 per cent hydronephrosis, 12 per cent chronic pyelonephritis). 2. The incidence of V.U. reflux on micturating cysto-urethrography was 13 per cent. V.U. reflux is associated with chronic pyelonephritis in a high proportion of cases as would be expected. A normal pyelogram does not exclude V.U. reflux as mentioned by Cobb (1966). 3. Patients with complete paralysis show a significantly high incidence of chronic pyelonephritis, hydronephritis and V.U. reflux. 4. In case of unilateral hydronephrosis and chronic pyelonephritis there is a striking predilection for involvement of the right kidney. The cause for this is not evident but possibly the fact that the right ureter is shorter than the left is a factor.

Thirty-two patients with tubercular lumbar spondylodiskitis were studied by using traditional x-rays and echography. Computed tomography (CT) scans were also employed in six patients. Ultrasound scans detected tubercular abscesses in 17 cases, whereas traditional x-rays diagnosed abscesses in only 10. Echographic patterns are reported depending on the site and contents. Besides assessing the abscess, it was possible to diagnose a case complicated with hydronephrosis due to compression of the ureter. Analysis of the results obtained indicates that the association of traditional x-rays with echography is sufficient to obtain, in most cases, complete and exact diagnoses and that using CT scans can be limited to doubtful cases or those complicated by paraplegia.

From May 1988 to September 1994, 15 spinal cord injury patients were treated by piezoelectric extracorporeal shock wave lithotripsy. Aged from 23 to 71 years (mean = 39), they presented with a total of 23 stones, of which 18 were located in the calyces, three in the renal pelvis and two in the proximal ureter. The maximum dimensions of calculi varied from 5 to 35 mm (mean = 11). Patients were placed in a dorsal decubitus position during the sessions, three being sedated with diazepam, while the other 12 remained unsedated. All were treated routinely with systemic antibiotics. Auxiliary procedures consisted of two pyelocalyceal flushings, three double J ureteral stenting and three ureteroscopies with fragment removal with a Dormia basket. No episode of autonomic dysreflexia was observed. Short term side effects were limited to a few cases of gross haematuria which regressed spontaneously. Overall, eight successes (53%), and seven failures (47%), were registered. Of the failures, one was the result of a partial fragmentation, while six were related to intrarenal retention of residual fragments resulting in four cases in rapid recurrences. Extracorporeal shock wave lithotripsy can be easily applied to spinal cord injury patients. Its usefulness and limitations need to be well understood and a global consideration must be applied to the prevention and early detection of the upper urinary calculi in this exposed population of patients.

Lumbar sympathetic block (LSB) is used in the management of sympathetically maintained pain states. Complications of LSB include infection, injury of spinal cord or somatic nerve, kidney trauma, hypotension, paraplegia and genitofemoral neuralgia. This report presents the case of a 53-year-old woman who had undergone LSB for relief of reflex sympathetic dystrophy and subsequently disrupted right proximal ureter. She was treated with ureteroureterostomy and indwelling ureteral stent.

A male patient with spina bifida and paraplegia, born in 1968, underwent urostomy in 1973. In 1999, he developed urine infections. Intravenous urography showed bilateral hydronephrosis and hydroureter. This patient continued to get recurrent urine infections. In 2009, computed tomography of the abdomen revealed dilatation of the ureters, but the ureters reverted to normal calibre as they passed forward through the anterior abdominal wall. The vas deferens on either side was crossing and kinking the ureter. Magnetic resonance imaging of the abdomen confirmed that the level of obstruction in both ureters was at the site where the vas deferens crossed the ureter and kinked it. While performing urostomy, the ureters below the crossover by the vas deferens were detached from the bladder and attached to the skin for urinary diversion, thus causing the vas deferens to hook the lower end of the ureters. As the patient gained height and weight, thereby increasing abdominal girth, kinking of the ureters by the vas deferens was accentuated. In hindsight, bilateral midline cutaneous urostomy using the ureters below the crossover by the vas deferens represents a poor surgical technique for urinary diversion.

Paediatric Chance fracture are rare lesions but often associated with abdominal injuries. We herein present the case of a seven years old patient who sustained an entrapment of small bowel and an ureteropelvic disruption associated with a Chance fracture and spine dislocation following a traffic accident. Initial X-rays and computed tomographic (CT) scan showed a Chance fracture with dislocation of L3 vertebra, with an incarceration of a small bowel loop in the spinal canal and a complete section of the left lumbar ureter. Paraplegia was noticed on the initial neurological examination. A posterior L2-L4 osteosynthesis was performed firstly. In a second time she underwent a sus umbilical laparotomy to release the incarcerated jejunum loop in the spinal canal. An end-to-end anastomosis was performed on a JJ probe to suture the left injured ureter. One month after the traumatism, she started to complain of severe headaches related to a leakage of cerebrospinalis fluid. Three months after the traumatism there was a clear regression of the leakage. One year after the trauma, an anterior intervertebral fusion was done. At final follow-up, no neurologic recovery was noticed. In case of Chance fracture, all physicians should think about abdominal injuries even if the patient is asymptomatic. Initial abdominal CT scan and magnetic resonance imaging provide in such case crucial info for management of the spine and the associated lesions.
