Intermediate-term oncological outcomes of hand-assisted laparoscopic versus open bilateral nephroureterectomy for dialysis and kidney transplant patients with upper urinary tract urothelial carcinoma

Simultaneous radical cystectomy and nephroureterectomy in the treatment of panurothelial carcinoma: a systematic review and single-arm meta-analysis

Background

Panurothelial carcinoma is a rare and aggressive malignancy that requires effective treatment strategies to enhance patient outcomes.

Methods

We conducted a systematic search of English publications in databases including PubMed, Embase, Cochrane Library, and Web of Science up to May 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale (NOS) and the Methodological Quality and Synthesis of Case Series and Case Reports tool. Data statistics and analysis were performed using Stata 15.1 software (StataSE, USA).

Results

Six studies involving 339 patients were included in the analysis. Meta-analysis revealed that Simultaneous Radical Cystectomy and Nephroureterectomy had 2-year and 5-year overall survival rates of 68% (95% CI 60%-76%, I2 = 12.4%, P < 0.001) and 44% (95% CI 36%-53%, I2 = 0, P < 0.001), respectively. The 2-year and 5-year progression-free survival rates were 91% (95% CI 86%-95%, I2 = 95%, P < 0.001) and 65% (95% CI 58%-73%, I2 = 91.5%, P < 0.001), respectively. The 2-year and 5-year cancer-specific survival rates were 73% (95% CI 66%-81%, I2 = 16.7%, P < 0.001) and 57% (95% CI 49%-66%, I2 = 0, P < 0.001), respectively. Additionally, the incidence of minor complications was 19% (95% CI 15%-23%, P < 0.01), major complications was 49% (95% CI 34%-63%, P < 0.01), and the intraoperative blood transfusion rate was 53% (95% CI 44%-61%, P < 0.01).

Conclusions

Simultaneous radical cystectomy and nephroureterectomy represent feasible approaches for the treatment of Panurothelial carcinoma. Nonetheless, a comprehensive assessment of the surgical risks and benefits is imperative, and larger-scale prospective cohort studies are required to validate therapeutic efficacy.

Comparison between completely and traditionally retroperitoneoscopic nephroureterectomy for upper tract urothelial cancer

Background

To evaluate the safety and efficacy of the completely retroperitoneoscopic nephroureterectomy (CRNU), a retrospectively comparative study between completely and traditionally retroperitoneoscopic nephroureterectomy (TRNU) was done in a single center.

Methods

From January 2014 to December 2014, 107 patients with upper tract urothelial cancer (UTUC) underwent CRNU. The kidney was retroperitoneoscopically dissected and the bladder cuff was cut by endoscopic gastrointestinal automatic stapler, and the specimen was removed from a 6-cm incision by posterior axillary line. Demographic, perioperative, and follow-up data were collected and compared retrospectively with 110 patients undergoing TRNU.

Results

The patients’ characteristics between the two groups were not statistically different (p > 0.05), and all patients successfully received the procedure. The mean operative time (106 ± 37.9 versus 199 ± 69.1 min, p < 0.0001), the mean estimated blood loss (47.2 ± 82.4 versus 166.9 ± 250.9 ml, p = 0.002), and the mean hospital stay (6.1 ± 3.5 versus 8.1 ± 3.3 days, p = 0.03) of the CRNU group decreased significantly compared to the traditional group. The operative time was not affected by gender. No open conversion and major complications occurred. The surgical margin of the ureter was all negative. The mean follow-up time was 13.4 months for the CRNU group and 37.5 months for the TRNU group. All follow-up patients in the CRNU group were alive without local recurrence. No cases of port site metastasis and local recurrence were observed in both groups. Bladder tumor recurrence occurred in 4 patients of the CRNU group and 21 patients of the TRNU group.

Conclusions

The CRNU using an endoscopic gastrointestinal automatic stapler to manage the bladder cuff is feasible and advantageous in decreasing the operative time, the blood loss, and the hospital stay. However, a larger sample and longer follow-up time will be still required.

A modified single mini-incision complete urinary tract exenteration for urothelial carcinoma in dialysis patients

Objective. To present our experience with single mini-incision complete urinary tract exenteration (CUTE) for female dialysis patients suffering from urothelial carcinoma (UC). Patients and Methods. Institutional review board approval was obtained. From 2005 through 2012, 14 female dialysis patients with UC underwent single mini-incision CUTE, in combination with radical hysterectomy and bilateral salpingo-oophorectomy. All were placed in the modified dorsal lithotomy position without repositioning. An infraumbilical midline mini-incision was made. Bilateral nephroureterectomy was first performed entirely extraperitoneally, followed by radical cystectomy with removal of the uterus and ovaries transperitoneally. Results. All procedures were done successfully without major complications. The median operative time was 242.5 minutes, and estimated blood loss was 500 mL. The median time to oral intake was 2 postoperative days; the median hospital stay was 11 days. Ten patients remained cancer-free at a median follow-up of 46.5 months; six patients were confirmed as having preoperatively undetectable UC or renal cell carcinoma, even after reviewing preoperative computed tomography. Conclusions. This modified technique provides a time-saving complete urinary tract extirpation to eliminate preoperatively undetectable malignancy, reduce metachronous recurrences, and avert perioperative complications associated with pneumoperitoneum and repositioning. Good cancer control and early convalescence can mutually be achieved in experienced hands.

Bilateral hand-assisted laparoscopic renal surgery in the supine position: the spleen at risk

OBJECTIVE

We evaluated the safety of simultaneous bilateral renal procedures performed using hand-assisted laparoscopy (HAL) with the patient in the supine position.

MATERIALS AND METHODS

After securely strapping the patient to the table, a hand-port device is placed via a 7-cm supraumbilical or peri-umbilical incision with two to four 5-mm to 12-mm trocars placed bilaterally. During a 3-year period, 8 bilateral HAL renal operations were initiated (upper pole partial nephrectomies, 3 nephroureterectomies, 3 bilateral nephrectomies, and right nephrectomy with left adrenalectomy).

RESULTS

Mean patient age was 41 years. One patient with ADPKD required conversion to open due to failure to progress secondary to excessive perirenal fat and 22-cm kidneys. The other 7 were completed successfully with a mean operative time of 417 minutes and mean EBL of 336cc. Two patients received transfusions. Two small splenic lacerations, managed conservatively, were the only complications.

CONCLUSIONS

Bilateral hand-assisted laparoscopic renal surgery with the patient in the supine position (rolling the table side to side) is feasible in the majority of patients. However, very large kidneys (eg, ADPKD) may be better approached with the patient in the lateral decubitus position or via an open subcostal incision. Importantly, the spleen appears to be at increased risk for capsular injury due to apparent increased difficulty of left colon mobilization in the "rolled" or "airplaned" supine position.

Surgical management of upper tract urothelial carcinoma

Upper tract urothelial cell carcinoma accounts for 5% of all urothelial tumors. Compared to lower urinary tract tumors, upper tract urothelial carcinoma is diagnosed more frequently at advanced stages. Open radical nephroureterectomy remains the gold standard treatment option for upper tract tumors. However, with the advancement of minimally invasive techniques and the benefits of these procedures regarding perioperative morbidity, cosmesis, and earlier convalescence, these options have shown promise in managing the patients with upper tract urothelial carcinoma. Despite the perioperative advantages, concerns exist on the oncological safety after minimally invasive surgery. In this article, we provide a comprehensive overview of the surgical management of upper tract urothelial carcinoma.

Simultaneous robot-assisted nephroureterectomy and cystectomy in patients with uremia and multifocal urothelial carcinoma

BACKGROUND AND PURPOSE

In Taiwan, patients with uremia have a high risk of the development of multifocal urothelial carcinoma. We report on eight patients with uremia and urothelial carcinoma who underwent simultaneous robot-assisted laparoscopic nephroureterectomy and radical cystectomy (RANUC).

PATIENTS AND METHODS

Between April 2006 and August 2010, eight patients with uremia (five women, three men; mean age 66.9  y) who were receiving dialysis underwent RANUC. Patients were classified into two groups: Group I, cases 1 to 4 occurring between April 2006 and June 2009; and group II, cases 5 to 8 occurring between July 2009 and August 2010.

RESULTS

The mean operative time was significantly shorter in group II (252.5±35.0  min vs 360±25.8  min; P=0.029). The estimated blood loss was also significantly less in group II (332.5±53.8  mL vs 660±137.4  mL; P=0.029). The blood transfusion rate was 75% in group I and 0% in group II. The postoperative stay was reduced from 8.5 days for group I to 7 days for group II. No perioperative morbidity and mortality were noted in either group. None of the patients had died at the short- and intermediate-term mean follow-up of 28.1 months (range 2-54  mos).

CONCLUSIONS

Simultaneous RANUC are feasible and can be performed safely. Long-term oncologic data are awaited; however, at intermediate-term oncologic follow-up, results are satisfactory. RANUC for uremic patients with multifocal urothelial carcinoma necessitating complete urinary tract exenteration is a viable option and patients experience a rapid convalescence.

Bilateral hand-assisted retroperitoneoscopic nephroureterectomy (HARN) in the spread-eagle position for dialysis patients-low midline HARN in a completely supine position

OBJECTIVES

To evaluate the feasibility of hand-assisted bilateral retroperitoneoscopic nephroureterectomy (HARN) in a completely supine position (spread-eagle position [SEP]) for dialysis patients with bilateral upper urinary tract tumors.

METHODS

From October 2006 to May 2009, bilateral HARN with open bladder cuff excisions were performed in 13 dialysis patients with upper urinary tract tumors. The patient was placed supine with both legs extended and abducted at 45-60 degrees and both arms stretched out to the sides in a SEP. The operation was completed via a 7- to 8-cm lower midline incision and 4 laparoscopic ports (2 on each side).

RESULTS

All procedures were successful. The mean operation time of bilateral HARN and open bladder cuff resection was 215 minutes, and the mean estimated blood loss was 216 mL. The time to oral intake was 2.5 days and to ambulation was 4.3 days. All patients recovered uneventfully to normal daily activity. No specific complication was related to the position.

CONCLUSIONS

Bilateral HARN in a completely supine, SEP position is feasible and safe. SEP has several advantages, including ease in patient positioning, and the feasibility to perform simultaneous bilateral nephroureterectomy without repositioning of the patient. It also avoids potential risks associated with the lateral decubitus position. Bowel interference of the visual field and mechanical bowel injury are not concerns in this approach. Our experience shows that a completely supine position is not only possible but also advantageous to bilateral HARN.
