PURPOSE: To evaluate the outcomes of rigid ureterorenoscopy (URS) for renal pelvic stones (RPS) sized 1 to 2 cm and to determine the predictive factors for the requirement for flexible URS (F-URS) when rigid URS fails. MATERIALS AND METHODS: A total of 88 patients were included into the study. In 48 patients, the RPS were totally fragmented with rigid URS and F-URS was not required (group 1). In 40 patients, rigid URS was not able to access the renal pelvis or fragmentation of the stones was not completed owing to stone position or displacement and F-URS was utilized for retrograde intrarenal surgery (RIRS) (group 2). The predictive factors for F-URS requirement during RIRS for RPS were evaluated. Both groups were compared regarding age, height, sex, body mass index, stone size, stone opacity, hydronephrosis, and previous treatments. RESULTS: The mean patient age was 48.6+/-16.5 years and the mean follow-period was 39+/-11.5 weeks. The overall stone-free rate in the study population was 85% (75 patients). In groups 1 and 2, the overall stone-free rates were 83% (40 patients) and 87% (35 patients), respectively (p>0.05). The independent predictors of requirement for F-URS during RIRS were male gender, patient height, and higher degree of hydronephrosis. CONCLUSIONS: Rigid URS can be utilized in selected patients for the fragmentation of RPS sized 1 to 2 cm with outcomes similar to that of F-URS. In case of failure of rigid URS, F-URS can be performed successfully in this group of patients.

Carcinosarcomas are rare biphasic malignant neoplasms with an epithelial and a spindle cell component. We present a 62-year-old man with a history of noticeably abdominal distension, proved by surgery to be caused by carcinosarcoma of the renal pelvis and urinary bladder, occupying the entire left abdominal flank. We also illustrate the appearance of this rare entity on sonography and computed tomography.

OBJECTIVETo evaluate the technique and the clinical efficacy of Retroperitoneoscopic dismembered pyeloplasty in children.
METHODSRetroperitoneoscopic dismembered pyeloplasty was performed on 17 patients of pediatric ureteropelvic junction (UPJ) obstruction, age ranging from 3 - 10 years. All patients had radiographic evidence of obstruction with signs, symptoms or deterioration of renal function.
RESULTSAll of the 17 operations were performed successfully, and no serious complications occurred during and after the operations. Average operating time was 4.3 hours, which decreased with surgeon experience. Average blood loss was 38 ml, mean postoperative stay was 4.6 d. Only one case had postoperative urine leakage. With a mean follow-up of 14 months, all patients were free of obstruction on follow-up radiographic imaging.
CONCLUSIONSRetroperitoneoscopic dismembered pyeloplasty is a safe, effective and minimally invasive procedure for treatment of UPJ obstruction in children, and it can be used as an alternative to open surgery.

OBJECTIVETo explore the clinicopathological features, immunophenotype, differential diagnosis, pathogenesis and prognosis of villous adenoma with poorly differentiated adenocarcinoma of the urinary tract.
METHODSClinical and pathologic findings of 3 cases of villous adenoma with poorly differentiated adenocarcinoma of the urinary tract were analyzed by gross examination, microscopic investigation and immunohistochemical staining. The related literatures were reviewed.
RESULTSAll of the three cases were middle-aged or elderly patients. Three cases all presented with hematuria and mucusuria. Endoscopic examination identified that case 1 had a polyp with broad attachment in the dome of bladder, case 2 had a solid mass in the ureter, and case 3 had a exophytic fungating tumor in the renal pelvis. Microscopically, case 1 revealed a papillary lesion with finger-like processes lined by pseudostratified columnar epithelium with abundant goblet cells. The cells demonstrated moderate degree dysplasia. In case 2 and case 3, both villous adenomas and poorly differentiated adenocarcinoma were observed, the adenoma cells arranged in a cribriform pattern, and the tumor cells showed severe atypia, mitotic activity, and transition with invasive poorly differentiated adenocarcinoma. Immunohistochemically, the tumor cells in three cases were positive for CK20, CEA,EMA and MUC-1; none of them expressed cdx-2 and PSA; In case 2 and 3, the same immunophenotype of villous adenomas and their associated adenocarcinomas was observed, but the number of the positive cells of p53 and Ki-67 staining were significantly increased in the area of adenocarcinomas than in that of the villous adenomas.
CONCLUSIONSVillous adenoma of the urinary tract is rare. It can occur in the urinary bladder, urachus, renal pelvis, ureter and urethra. These lesions may have malignant potential and frequently coexist with other malignant tumors. So, villous adenoma of the urinary tract should be removed completely and sampled thoroughly to avoid missing a more aggressive component.

Renal pelvic transitional cell carcinoma (TCC), which invades beyond muscularis into peripelvic fat or the renal parenchyma, is diagnosed as stage pT3 despite its structural complexity. We evaluated the prognostic impact of peripelvic fat invasion in pT3 renal pelvic TCC. Between 1986 and 2004, the medical records on 128 patients who were surgically treated for renal pelvic TCC were retrospectively reviewed. Sixty patients with pT3 disease were eligible for the main analysis. The prognostic impact of various clinicopathological factors was analyzed using univariate and multivariate analyses. On univariate analysis, sex, age, concomitant bladder tumors, concomitant ureter tumors, lymphadenectomy, adjuvant chemotherapy, tumor grade, multiplicity, renal parenchymal invasion, and carcinoma in situ did not influence the disease-specific survival (p>0.05). By contrast, peripelvic fat invasion, lymph node invasion, and lymphovascular invasion were each significantly associated with disease-specific survival (p<0.05). Multivariate analysis showed that peripelvic fat invasion (p=0.012) and lymph node invasion (p=0.004) were independent prognostic factors. In conclusion, peripelvic fat invasion is a strong prognostic factor in pT3 renal pelvic TCC. Thus, systemic adjuvant therapy should be considered in the presence of peripelvic fat invasion, even if the lymph nodes are not involved.
