Extranodal extension is a powerful prognostic factor in bladder cancer patients with lymph node metastasis.

Background: Lymph node metastasis (LNM) is the most powerful pathologic predictor of disease recurrence after radical cystectomy (RC). However, the outcomes of patients with LNM are highly variable.

Objective: To assess the prognostic value of extranodal extension (ENE) and other lymph node (LN) parameters.

Pathologic nodal staging score for bladder cancer: a decision tool for adjuvant therapy after radical cystectomy.

Background: Radical cystectomy (RC) with pelvic lymph node dissection (PLND) is the standard of care for high-risk non-muscle-invasive and muscle-invasive bladder cancer (BCa).

Objective: To develop a model that allows quantification of the likelihood that a pathologically node-negative patient has, indeed, no positive nodes.

Design, Setting, And Participants: We analyzed data from 4335 patients treated with RC and PLND without neoadjuvant chemotherapy at 12 international academic centers.

Laparoscopic treatment for renal hydatid cyst.

A multivesicular hydatid cyst was removed from the left kidney of a 26-year-old woman by retroperitoneal laparoscopy to avoid contamination of the abdominal cavity. A scolicidal agent (20% hypertonic saline) was injected around the kidney initially and then instilled into the cyst after the contents had been evacuated. There were no complications and no anaphylactic shock.

[Giant retroperitoneal liposarcoma].

The authors report a case of giant retroperitoneal liposarcoma. The diagnosis was suspected after scanography and magnetic resonance imaging and confirmed by the histological analysis of the extracted piece after surgical treatment. Postoperative evolution was favourable after one year without recurrence or distant metastasis.

[Appendicular ureteroplasty to repair a ureteric lesion during disk surgery].

Extensive ureteric lesions raise difficult problems of surgical repair. This is also the case for upper ureteric lesions that often require replacement of the damaged segment or even autologous transplantation. The authors report a case of iatrogenic ureteric lesion resulting in a large defect in a patient operated 6 months previously for an L4-L5 disk hernia, which was treated successfully by interposition of an appendicular graft between the two ureteric stumps.
