Subjects
Urinary Bladder, Humans, Female, Middle Aged, Ureter, Fibrosis, Ureterostomy, Psoas Muscles

The psoas bladder hitch is an invaluable surgical procedure in the treatment of lesions of the lower ureteral third and transplantation with short ureters. We briefly review this procedure and describe an illustrative case of ureteroneocystostomy of the right lumbar ureter.

2. [Leiomyosarcoma and liposarcoma: rare tumors of the kidney]

Author

J A, Zabala Egurrola, A, Moratalla Basante, C, Pertusa Peña, A, Arruza Echebarría, R, Llarena Ibargue, and M, Acha Pérez

Subjects

Abstract

Sarcoma accounts for 2.8% of all renal tumours. We report a case of renal leiomyosarcoma (T2 N0 M0) and a case of renal liposarcoma (T3 N0 M0) submitted to surgery and chemo- and radiotherapy. Follow-up at nine months and 4 years, respectively, revealed the patients are tumor-free. The literature is reviewed highlighting the beneficial effect of chemo- and radiotherapy combined with surgery in the treatment of these tumors with a poor prognosis per se.

Abstract

Seven cases of hydatid renal cyst seen at our department over the past 8 years are described. The literature is reviewed and the importance of conservative surgery in the treatment of this disease is highlighted.

4. [Renal carcinoma presenting as a multilocular cyst]

Author

C, Pertusa Peña, R, Llarena Ibarguen, A, Arruza Echebarría, J A, Zabala Egurrola, M, Acha Pérez, and J, Tanago Araluce

Subjects
Adult, Polycystic Kidney Diseases, Humans, Female, Adenocarcinoma, Diagnostic Errors, Kidney Neoplasms
Abstract

Although it is not uncommon to find small foci of cystic degeneration in renal adenocarcinoma, it is uncommon to find these so extensive as to permit a preoperative diagnosis of multilocular cyst as in the present case. Several etiopathogenic mechanisms have been described. In the present case, the underlying mechanisms are likely to be tumor necrosis and intrinsic multilocular cystic growth. Arteriography is not the best diagnostic method and there are doubts as to the usefulness of punction aspiration. Prognosis remains unclear.
