Abstract:
Objective To review the diagnosis and treatment of squamous cell carcinoma of renal pelvis. Methods The clinical data from October 1991 to May 2009 of eight cases of squamous cell carcinoma of renal pelvis were reviewed and analyzed retrospectively. The symptoms of the patients were hematuria (eight cases), pain (seven cases) and abdominal mass (one case). All patients underwent B-ultrasound and IVU examination and four cases underwent CT scan. Three cases were diagnosed as having a tumor before surgery. Five cases were diagnosed as renal calculus, two of the five cases were diagnosed by intraoperative frozen section. Radical nephroureterectomy were performed in four cases, nephrectomy in three cases and palliative resection in one case. Results Histological classification revealed that six cases were moderately differentiated, one case was well differentiated and one case was poorly differentiated. Two cases had stage pT1/pT2 and six cases had stage pT3/pT4. 2 cases had regional lymph nodes metastasis. Seven cases were followed-up. All patients died of tumor recurrence or metastasis. The median tumor specific survive time was six months (range from two months to 42 months). Conclusions Squamous cell carcinoma of renal pelvis is often occurs concurrently with urolithiasis which could lead to difficulty in diagnose before operation. As the most of the patients were diagnosed with advanced stage disease, squamous cell carcinoma of renal pelvis tended to early recurrence and metastasis and the prognosis was very poor.
