Robot assistance has been rapidly adopted by urological surgeons and has become particularly popular for oncological procedures involving the retroperitoneal space. The wide dissemination of robot assistance probably reflects the limited amount of operating space available within the retroperitoneum and the advantages provided by robot-assisted approaches, including 3D imaging, wristed instrumentation and the shorter learning curve compared with that associated with the equivalent laparoscopic techniques. Surgical procedures that have traditionally been performed using an open or laparoscopic approach, such as partial nephrectomy, radical nephrectomy, retroperitoneal lymph node dissection, nephroureterectomy and adrenalectomy, are now often being performed using robot assistance...

STUDY OBJECTIVE: To show total laparoscopic resection of a cervical carcinoma that recurred at the left pelvic sidewall after radical hysterectomy and concurrent chemoradiotherapy (CCRT). DESIGN: A step-by-step demonstration of the technique in a surgical video, including the strategy for achieving complete surgical resection with negative margins (R0 resection) (Canadian Task Force Classification III). SETTING: For high-risk cervical carcinoma, radical hysterectomy and adjuvant CCRT is the standard treatment, but even this multimodal therapy cannot prevent recurrence...

PURPOSE: Since conditional survival analysis provides better estimates of survival time at each followup, we assessed changes in conditional intravesical recurrence-free survival rates after radical nephroureterectomy. We also sought to determine how the impact of well-known risk factors evolves with time, particularly in patients with localized upper tract urothelial carcinoma. MATERIALS AND METHODS: We identified 364 patients with Ta-3N0M0 localized upper tract urothelial carcinoma who underwent open or laparoscopic radical nephroureterectomy at 1 of our 3 institutions...

OBJECTIVE: For locally advanced cervical carcinoma, concurrent chemoradiotherapy (CCRT) is the standard treatment, however, CCRT can lead to development of a vesicovaginal or rectovaginal fistula [1]. Treatment options are limited for patients with laterally recurrent cervical carcinoma and fistula formation after CCRT. Chemotherapy with bevacizumab is now used for recurrent or advanced cervical carcinoma, but this treatment is associated with fistula formation [2]. When the recurrent mass is confined to the pelvic cavity, complete surgical resection with negative margins offers the most promise; however, the resectability rate is low in cases of laterally recurrent tumor [3], which may include bony structures, and survival outcomes seem to be poor in cases of a laterally recurrent vs...

OBJECTIVES: To compare outcomes and survival of open-, robotic-, and laparoscopic nephroureterectomy (ONU, RNU, LNU) using population-based data. METHODS: Using the National Cancer Database, we identified patients who underwent nephroureterectomy for localized upper tract urothelial carcinoma between 2010 and 2013. Demographic and clinicopathologic characteristics were compared among the three operative approaches. Multivariate regression analyses were used to determine the impact of approach on performance of lymphadenectomy (LND), positive surgical margins (PSM), and overall survival (OS)...

Upper tract urothelial carcinoma is a relatively uncommon malignancy. The gold standard treatment for this type of neoplasm is an open radical nephroureterectomy with excision of the bladder cuff. This systematic review compares the perioperative and oncologic outcomes for the open surgical method with the alternative surgical management options of laparoscopic nephroureterectomy and robot-assisted nephroureterectomy (RANU). MEDLINE, EMBASE, PubMed, and Cochrane Library databases were searched using a sensitive search strategy...

INTRODUCTION: When performing open or laparoscopic nephroureterectomy (LNU), the optimal way to excise the distal ureter remains controversial. There are concerns that primary endoscopic detachment of the intramural ureter is associated with adverse outcomes. Existing studies have limited number of patients and inadequate oncologic follow-up. We provide our institutions experience of this technique. MATERIALS AND METHODS: Data were collected prospectively on 59 patients (37 men) who underwent LNU for a 10-year period at a single center using a standardized technique: initial endoscopic circumferential release of the distal ureter and bladder cuff followed by retroperitoneal en bloc LNU...

INTRODUCTION: To evaluate temporal trends in the delivery and extent of lymphadenectomy (LND) in radical nephroureterectomy (RNU) performed in upper tract urothelial carcinoma (UTUC) patients. METHODS: We evaluated a multi institutional collaborative database composed by 1512 consecutive patients diagnosed with UTUC treated with RNU between 1990 and 2016. Year of surgery were grouped in five periods: 1990-1996, 1997-2002, 2003-2007, 2008-2012 and 2013-2016. Data about LND were available for all patients and numbers of nodes removed and positive were reported by dedicate uropathologists...

A 68-year-old man underwent an inguinal orchiectomy for a right testicular tumor and the pathological diagnosis was atypical lipomatous tumor. Nine years later, a resection procedure was performed for local recurrence. Five years after that second surgery, abdominal computed tomography (CT) findings revealed a low density mass 40 mm in size on the back side of the right kidney and enlarged fat in the retroperitoneal space. We performed a laparoscopic tumor resection under a diagnosis of lipoma or liposarcoma recurrence, and the pathological diagnosis was well differentiated liposarcoma...

BACKGROUND: Many studies have reported the oncological outcomes between open radical nephroureterectomy (ONU) and laparoscopic radical nephroureterectomy (LNU) of upper tract urothelial carcinoma (UTUC). However, few data have focused on the oncological outcomes of LNU in the subgroup of localized and/or locally advanced UTUC (T1-4/N0-X). The purpose of this study was to compare the oncological outcomes of LNU vs. ONU for the treatment in patients with T1-4/N0-X UTUC. METHODS: We collected and analyzed the data and clinical outcomes retrospectively for 265 patients who underwent radical nephroureterectomy for T1-4/N0-X UTUC between April 2000 and April 2013 at two Chinese tertiary hospitals...
