ABSTRACT

Objective:

To investigate the clinical features of diagnosis and treatment of renal parenchymal invasive urothelial carcinoma.

Methods:

The clinical data of 23 patients with renal parenchymal invasive urothelial carcinoma admitted to Beijing Chaoyang Hospital Affiliated to Capital Medical University from January 2014 to December 2020 were retrospectively analyzed. There were 12 males and 11 females. The mean age was (67.3±10.1) years old. Among them, 7 cases complained of painless hematuria and 9 cases were asymptomatic. Three cases underwent preoperative MRI examination, 19 patients underwent preoperative enhanced CT examination, and 1 patient underwent both MRI and enhanced CT examination. MRI examination showed renal lobulated and other T1 mixed with T2 signals, the boundary was not clear, and DWI showed obvious restricted diffusion. The tumor was located on the left side in 15 cases and on the right side in 8 cases. Preoperative diagnosis was made by fine needle aspiration biopsy in 1 patient, and specimens were obtained by flexible ureteroscope in 2 patients. No tumor was reported. The preoperative diagnosis of 22 patients was unclear and the nature of the tumor could not be determined. One patient was considered to have urothelial carcinoma by fine needle aspiration. All patients were treated by surgery, including 20 cases of laparoscopic radical nephrectomy and 3 cases of nephroureterectomy with bladder sleeve resection.

Results:

Postoperative pathological specimens showed yellow-white mass, high-grade invasive urothelial carcinoma invading renal parenchyma. Nine cases were T 3a stage, 14 cases were T 3b stage, and 5 cases were lymph node metastasis. The average postoperative follow-up time was (18.6±6.72)months, 2 patients were lost to follow-up, 8 patients died, and the overall mortality rate was 38.1%. Seven patients died of recurrence or metastasis. There were 3 cases of bladder recurrence and 5 cases of metastasis after operation.

Conclusions:

Renal parenchymal infiltrating urothelial carcinoma is difficult to diagnose in the early stage, with poor clinical biological behavior and poor overall prognosis. For patients diagnosed with renal parenchymal invasive urothelial carcinoma preoperatively, laparoscopic nephroureterectomy + bladder sleeve resection is recommended.
