To compare perioperative circulating tumor cells (CTC) in primary upper tract urothelial carcinoma (UTUC) patients who underwent hand-assisted retroperitoneoscopic nephroureterectomy (HANU) or robotic-assisted nephroureterectomy (RANU). A total of 29 patients received RANU (n = 10) or HANU (n = 19). Peripheral blood samples were collected before, 24 h after surgery (POh24) and on postoperative day 28 (POD28). The demographic and pathologic data are similar in both groups. RANU had a longer operative time (p = 0.031), less bleeding volume (p = 0.004), and comparable pain sore (p = 0.169). The mean CTC numbers before surgery (2.4 vs. 2.3, p = 0.482), POh24 (2.4 vs. 1.9, p = 0.668) and POD28 (0.5 vs. 0.6, p = 0.280) were not significant different among groups. The amount of CTCs in both groups decreased and reached similar level on POD28. No significant difference of overall and intravesical recurrence rate between the two approaches. In comparison to RANU, more surgical manipulation does not affect tumor cell translocation into the bloodstream in UTUC patients who received HANU. However, a longer follow-up would be needed for the final comparison of tumor recurrence.

Introduction: Benign prostatic hyperplasia, bladder outlet obstruction, and overactive bladder are major causes of lower urinary tract symptoms (LUTS). Tumor compression of the urinary bladder resulting in LUTS was clinically observed. Gastrointestinal stromal tumors (GISTs) presenting with LUTS have not been reported before. Herein, we report a patient with extraluminal GIST of the ileum who had LUTS without gastrointestinal symptoms during the clinical course. Patient concerns: A 68-year-old man visited the genitourinary outpatient department because of frequent urination with mild dysuria. He also complained of poor appetite, fatigue, and body weight loss of 10 kg over 6 months. A large presacral solid mass lesion compressing the bladder and surrounded by the bowel with gas content was identified through abdominal computed tomography. Diagnosis: GIST of the ileum with mesenteric invasion was revealed by pathological examination. Interventions: Exploratory laparotomy with removal of the pelvic tumor and segmental resection of the ileum was performed. Outcomes: Now, he received adjuvant imatinib target therapy for 1 year with stable condition. Conclusion: Extravesical compression or invasion of the urinary bladder by a pelvic mass lesion is common but is rarely accompanied by GISTs of the ileum. Specific findings identified through imaging should alert the surgeon to this specific entity and prepare thoroughly before surgical intervention.

Isolated bony metastasis from prostate cancer is extremely rare, thus, the efficiency of its surgical resection remains unclear. We present a case of isolated left sixth rib metastasis from prostate cancer that was treated with metastasectomy and androgen deprivation therapy. Salvage radical prostatectomy was conducted subsequently, successfully downstaging the tumor.

At present, robot-assisted radical prostatectomy (RARP) is a gold standard in radical prostatectomy. The aim of this study was to evaluate the incidence, risk factors, and timing of occurrence of inguinal hernia (IH) after RARP.We included 427 patients with prostate cancer who underwent RARP
