[Vascular complications in renal transplantation].

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.

[Testicular seminoma manifested by carcinomatous neuropathy: an unusual presentation. Review of the literature].

Contribution of one patient with tetraparesic picture originated by a major sensory-motor neuropathy, due to paraneoplastic syndrome produced by a testicular seminoma. The patient underwent inguinal orchiectomy and radiotherapy, with favourable evolution of his neurological symptomatology. Review of the literature and confirmation of the extraordinary rarity of such clinical picture.

Control of massive hematuria in idiopathic hemorrhagic cystitis after administration of conjugated estrogen.

A renal transplant patient with severe hemorrhagic cystitis of idiopathic etiology was treated initially with intravenous administration of conjugated estrogen (1 mg./kg.), followed on day 2 and thereafter with 5 mg. per day orally for 3 weeks. Hematuria decreased in intensity within 10 hours and disappeared within 48 hours. Hematuria did not recur by 6 months after completion of oral doses of conjugated estrogen. Complications or other side effects were not observed. In our experience conjugated estrogen controls hematuria in patients with idiopathic hemorrhagic cystitis and this form of treatment must be considered in this condition.

[Endourologic treatment of calyceal diverticulum complicated with lithiasis].

Presentation of 9 cases of calyceal diverticulum symptomatic lithiasis, 6 of which have been treated up to the present time. Of the remaining 3, one patients, in spite of its evolutive character (increased cavity) and moderate pain, prefers to abstain from therapeutic therapy, but undergoes follow-up controls every 6 months; the other 2 cases are waiting endourological treatment. Out of 6 patients who underwent surgery, two cases, who had previously experienced shockwave extracorporeal lithotripsy (SWEL), were advised to have endourological procedures due to persistence of pain and gallstones debris.

Lymphorrhea as postoperative complication of living donor nephrectomy: a case report.

We report a case of lymphorrhea after living donor nephrectomy. Clinically the donor presented with an increased flow of a liquid characteristic of lymph, which was treated successfully with iodinated povidone. The possible pathogenic mechanisms implicated in the development of lymphocele following renal transplantation are discussed.

Bone metaplasia in the urinary tract: a new radiological sign.

We report 7 cases of bone tissue in the upper urinary tract. Routine excretory urography was suspicious for renal lithiasis. However, pathological evaluation of the kidney tissue revealed bone metaplasia in all 7 cases. Retrospective examination of the first 6 cases showed a typical radiological sign, consisting of a radiopaque eccentric halo surrounding an area of lesser radiological density that, in turn, connected with the urothelium. These findings permitted a correct preoperative diagnosis of bone metaplasia in case 7. Accurate preoperative differentiation of bone metaplasia (false calculi) and true renal lithiasis is important owing to the different treatments required.

Diagnosis and management of lymphoceles after renal transplantation.

Eighteen lymphoceles developed after 199 renal transplantations, 11 being asymptomatic. Ultrasound was the most sensitive method of detection. Seven lymphoceles were symptomatic, pelvic mass and decreased renal function being the most frequent signs. Five lymphoceles were successfully treated by instillation of iodate povidone into the lymphatic cavity; there were no complications or recurrences. This is a simple, safe and inexpensive method for the treatment of lymphoceles after renal transplantation.

Spontaneous regression of renal transplant artery stenosis: a new case.

Stenosis of the renal graft artery is a relatively common complication in renal transplantation. Therapy consists of either transluminal angioplasty or surgical correction. Nevertheless some untreated cases show good spontaneous evolution. We describe a well-documented case of graft artery stenosis causing severe hypertension with declining renal function which experienced spontaneous resolution.

New location of milk-of-calcium.

A case of milk-of-calcium with an exceptional location is reported. The characteristics of milk-of-calcium are presented, with stasis and urinary tract infection being the most important etiologic factors in this case. Structurally the stones are formed by a central core of calcium phosphate surrounded by magnesium-ammonium phosphate (struvite).

Transabdominal sonography of seminal vesicles.

We evaluated 119 male patients for infertility and/or prostatitis. Transabdominal sonography of the seminal vesicles was performed and transverse sections were used to measure the height and breadth. A correlation was established with the characteristics of the semen, the volume of semen being related directly to the size of the vesicles. Male patients with semen abnormalities had seminal vesicles of greater diameters than those with normal semen. When patients with prostatitis are eliminated from this group the difference is insignificant.
