ABSTRACT
Citreicella aestuarii 357 is a member of the Roseobacter clade that was isolated without xenobiotic pressure from an oil-polluted sand sample from the Galician coast (Spain). Its genome sequence suggests an organoheterotrophic metabolism, including a wide catabolic potential for aromatic hydrocarbons.

The paper sums up our experience with kidneys which have undergone "bench" extracorporeal arterial surgery. The reasons making this procedure necessary were: renal graft from corpse donor presenting multiple arteries or arterial lesions (12 cases); orthoptic kidneys with stenotic lesions or arterial aneurism (5 cases); transplanted grafts which developed renal artery stenosis (2 cases). Incidence of arterial thrombosis and ureteral fistula was significantly higher in the first group than in grafts where no "bench" surgery had been performed. Medium- and long-term actuarial survival, however, showed no difference. In the second and third groups, extracorporeal arterial reconstructive surgery is a technique with a high risk for the loss of the involved renal unit.

Between the years 1979 and 1992 we a total of 479 renal transplants (RT) were performed. In 62 patients (12.9%) there were some clinically significant vascular complications. These have consisted of: 10 cases of arterial thrombosis (2%); 10 cases of venous thrombosis (2%); 5 cases of arterial and venous thrombosis (1%); 31 cases of arterial stenosis (6.5%); and 6 cases of acute haemorrhage originated at the vascular anastomosis level (1.2%). In all those cases with arterial or venous thrombosis, or both, it was necessary to perform transplantation. The arterial stenosis cases were treated with antihypertensive agents in 13 patients; with endoluminal percutaneous angioplasty (EPA) in other 13 patients and with surgery in 5. Both arterial stenosis and complications from their treatment resulted in 5 transplantations. In all cases with early post-surgical haemorrhage originated at the vascular anastomosis level, a surgical review and suture of bleeding site was performed. A total of 31 grafts (6.5%) were lost as a result of vascular complications.

We report on a rare case of bilateral ureteral triplicity with a definitive urinary diversion (Brickner loop ureteroileostomy) who presented a staghorn stone in the upper calyx of the left kidney. The patient was submitted to percutaneous nephrolithotomy with direct access to the upper calyx of the anomalous kidney. We discuss the indication for this treatment, which resolved the lithiasis in a single session and with no complications. Furthermore, this treatment modality is compared with ESWL and open surgery, which we reserve for failures or those cases where the percutaneous approach is contraindicated. Percutaneous nephrolithotomy can be considered a therapeutic alternative for lithiasis in patients with congenital malformation and/or urinary diversion.

We report on a pediatric patient who was evaluated for recurrent episodes of urinary tract infection. Evaluation by IVP, cystography and retrograde ureteropyelography revealed a complete ureteral duplicity, grade II vesicoureteral reflux in the lower half of the left kidney and a blind bifid ureter arising at the distal third of the right ureter. This is an uncommon condition (about 150 cases have been reported) difficult to diagnose if undetected by conventional radiological evaluation and retrograde ureteropyelography may be required. It may be associated with urological or other types of malformations. It is generally asymptomatic and with scant consequences, thus treatment is initially conservative. Surgical excision of the blind bifid ureter is warranted only when complications present. In the present case, prophylactic antibiotic therapy was instituted. At one year follow up, the patient is asymptomatic and urine cultures are negative.

Exposition of results obtained from the review of the surgical complications found in a series of 479 renal transplantations performed between 1978 and 1992 in our centre, although some of them lack clinical relevance. There was fluid accumulation in 69 patients, distributed between 31 perirenal haematoma. 17 lymphocele, 13 urinoma, 5 perirenal abscesses and 3 mixed. 27.7% required no action. Frequency of renal rupture was 18 cases, 9 due to acute rejection and 9 to vascular thrombosis. Incidence of urinary obstruction was 4.8% with 5.8% of urinary fistula. With regard to the surgical wound, 9 infections, 7 haematomas, 1 eventration and 1 necrotizing fasciitis were observed. Vascular complications consisted in 10 arterial thrombosis, 10 venous thrombosis, 5 mixed thrombosis and 31 arterial stenosis. Treatment instituted for the various cases, its evolution, and an statistical study of risk factors are illustrated.
