RESUMEN
BACKGROUND: Upper urinary tract urothelial carcinoma (UTUC) with multiple pathological types is extremely rare in the clinic, but the recurrence rate and mortality these patients are high. At present, there is no standard treatment for such cases. CASE PRESENTATION: We reported a case of ureteral urothelial carcinoma with squamous cell carcinoma and sarcomatoid carcinoma differentiation and rapid ileal metastasis and reviewed the literature related to different pathological types of upper urinary tract tumours to explore the diagnosis, treatment and prognosis characteristics of the disease, enhance our understanding of its clinical manifestations and history of evolution and provide guidance for avoiding missed diagnosis and misdiagnosis. CONCLUSION: There is no standard treatment for urinary malignant tumours with multiple pathological types; radical surgery is considered a suitable choice. Chemotherapy, targeted drug therapy and immunotherapy may be beneficial to the survival of patients. In short, these patients have a high risk of recurrence and metastasis and a poor prognosis.

To summarize surgical experiences with a new modified technique involving extraperitoneal single-incision robot-assisted laparoscopic radical prostatectomy based on Da Vinci SI system by reviewing case data, including follow ups, and to evaluate the safety and clinical efficacy of the surgical procedure. The case data from December 2020 to September 2022 of 321 patients undergoing modified single incision (without dedicated PORT) robotic-assisted laparoscopic radical prostatectomy via an extraperitoneal approach were reviewed. All procedures were performed by the same surgeon at our center. Perioperative data and postoperative urinary control, tumor control, and erectile function recovery were assessed. The immediate, 3-months, 6-months, 12-months, 18-months and 24-months complete urinary control rates were 34.3%, 56.6%, 79.7%, 85.7%, 89.6% and 90.7%, respectively; the 3-months, 6-months, 12-months, 18-months and 24-months biochemical recurrence rates were 3.4%, 5.2%, 9.1%, 21.7% and 30.2%, respectively; and for those with normal preoperative erectile function, the 3-months, 6-months, 12-months, 18-months and 24-months postoperative erectile function recovery rates were 52.2%, 60.0%, 70.7%, 72.2% and 73.9%, respectively. The new modified technique involving extraperitoneal single-incision robotic-assisted laparoscopic radical prostatectomy is safe and feasible. This technique has satisfactory surgical results, and this new method results in satisfactory urinary control, tumor control and recovery of erectile function. In addition, this new method is not limited to specific dedicated access devices, which facilitates its application.

To compare the clinical efficacy of an innovative modified single-incision technique without special extraperitoneal PORT with that of transperitoneal multi-incision robot-assisted laparoscopic radical prostatectomy and to explore the feasibility and safety of the former. A retrospective analysis was performed on 259 patients who received robot-assisted laparoscopic radical prostatectomy in the Robot Minimally Invasive Center of Sichuan Provincial People's Hospital between September 2018 and August 2021. Among them were 147 cases involving extraperitoneal single incision with no special PORT (Group A) and 112 cases involving multiple incisions by the transperitoneal method (Group B). Differences in age, PSA level, Gleason score, prostate volume, body mass index, clinical stage, lower abdominal operation history, and lymph node dissection ratio between the two groups were not statistically significant (P > 0.05). All operations were performed by the same operator. In this study, all 259 operations were completed successfully, and there was no conversion. There was no significant difference in transperitoneal blood loss, postoperative hospital stay, positive rate of incision margin, indwelling time of urinary catheter, satisfaction rate of immediate urine control, satisfaction rate of urine control 3 months after operation, positive rate of postoperative lymph node pathology or postoperative pathological stage between the two groups (P > 0.05). There were significant differences in operation time, postoperative exhaust time and incision length (P < 0.05). The modified extraperitoneal nonspecial PORT single-incision technique is safe and feasible for robot-assisted laparoscopic radical prostatectomy, and its curative effect is similar to that of transperitoneal multi-incision RARP. It has the advantages of a short operation time, less impact on the gastrointestinal tract and a more beautiful incision. The long-term effect of treatment needs to be further confirmed by prospective studies.

INTRODUCTION: Birt-Hogg-Dubé syndrome (BHDS) is a rare genetic disease. Renal cell carcinoma is the most serious complication of BHDS. The histological types of BHDS-related renal cell carcinoma are mostly mixed chromophobe/eosinophil and chromophobe cell types. BHDS with unclassified renal cell carcinoma is extremely rare. PATIENT CONCERNS: A 37-year-old man was admitted to the hospital because of lumbago and hematuria. DIAGNOSIS: Combined with abdominal enhanced CT and pulmonary CT, BHDS complicated with renal cell carcinoma was diagnosed, and right partial nephrectomy was performed. The postoperative pathological diagnosis was unclassified renal cell carcinoma. Gene detection revealed the FLCN frameshift mutation. OUTCOMES: No signs of recurrence were observed after regular follow-up. CONCLUSION: The pathogenesis of BHDS has not been fully elucidated, and the pathological type of BHDS with unclassified renal cell carcinoma is extremely rare. Through case presentation and review of related literature, this paper summarizes the diagnosis and treatment of BHDS complicated with unclassified renal cell carcinoma.
