A comparative study of quality of life issues relating to open versus laparoscopic nephrectomy: a prospective pragmatic study

Role of the Laparoscopic Approach for Complex Urologic Surgery in the Era of Robotics

(1) Introduction: The advent of robotic surgery led to the assumption that laparoscopic surgery would be replaced entirely. However, the high costs of robotic surgery limit its availability. The aim of the current study was to assess the feasibility of the 3D laparoscopic approach for the most complex urological procedures. (2) Materials and methods: We included in the current study all patients who had undergone complex 3D laparoscopic procedures in our department since January 2017, including radical nephrectomy (LRN) using a dual combined approach (19 patients), radical nephroureterectomy (LRNU) with bladder cuff excision (13 patients), and radical cystectomy (LRC) with intracorporeal urinary diversion (ICUD) (21 patients). (3) Results: The mean operative time was 345/230/478 min, the complications rate was 26%/30.76%/23.8% and positive surgical margins were encountered in 3/1/1 patients for the combined approach of LRN/LRNU/LRC with ICUD, respectively. A single patient was converted to open surgery during LRN due to extension of the vena cava thrombus above the hepatic veins. After LRC, sepsis was the most common complication and 8 patients were readmitted at a mean of 15.5 days after discharge. (4) Conclusions: In the era of robotic surgery, laparoscopy remains a plausible alternative for most complex oncological cases.

Quality of life outcomes in patients with localised renal cancer: a literature review

Purpose

Patients with localised renal cell carcinoma (RCC) can expect excellent oncologic outcomes. As such, there has been a shift towards maximising health-related quality of life (HRQoL). A greater understanding of HRQoL outcomes associated with different treatment options for RCC can facilitate patient-centred care, shared decision-making and enable cost utility analyses to guide health policies. The aim of this literature review was to evaluate the evidence regarding HRQoL following different management strategies for localised RCC.

Methods

Three databases were searched to identify studies reporting HRQoL in patients with localised renal cancer, including Medline, the Tuft’s Medical Centre Cost Effectiveness Analysis registry and the EuroQol website.

Results

Considerable methodological heterogeneity was noted. Laparoscopic nephrectomy was associated with significantly better short-term physical function compared to open surgery, although the effect on mental function was inconclusive. Nephron-sparing surgery was associated with better physical function compared to radical surgery. Patients’ perception of remaining renal function was a significant independent predictor of HRQoL, rather than surgery type. Tumour size, stage, post-operative complications, age, body mass index, occupational status, educational level and comorbidities were significant predictors of HRQoL. Only three studies were available regarding non-surgical management options and very little data were available regarding the impact of follow-up protocols and long-term effects of “cancer survivorship.”

Conclusion

There is a need for validated and reproducible RCC-specific HRQoL instruments and standardisation amongst studies to enable comparisons. Increased awareness regarding determinants of poor HRQoL may enable high-risk patients to receive tailored support.

Cost-utility analysis of radical nephrectomy versus partial nephrectomy in the management of small renal masses: Adjusting for the burden of ensuing chronic kidney disease

OBJECTIVES

We compare the cost-utility of laparoscopic radical nephrectomy (LRN), laparoscopic partial nephrectomy (LPN) and open partial nephrectomy (OPN) in the management of small renal masses (SRMs) when the impact of ensuing chronic kidney disease (CKD) disease is considered.

METHODS

We designed a Markov decision analysis model with a 10-year time horizon. Estimates of costs, utilities, complication rates and probabilities of developing CKD were derived from the literature. The base case patient was assumed to be a 65-year-old patient with a <4-cm unilateral renal mass, a normal contralateral kidney and a normal preoperative serum creatinine. Univariate and probabilistic sensitivity analyses were conducted to address the uncertainty associated with the study parameters.

RESULTS

OPN was the least costly strategy at $25 941 USD and generated 7.161 quality-adjusted life years (QALYs) over 10 years. LPN yielded 0.098 additional QALYs at an additional cost of $888 for an incremental cost-effectiveness ratio of $9057 per QALY, well below a commonly cited willingness-to-pay threshold of $50 000 per QALY. LRN was more costly and yielded fewer QALYs than OPN and LPN. Sensitivity analyses demonstrated our model to be robust to changes to key parameters. Age had no effect on preferred strategy.

CONCLUSIONS

Partial nephrectomy (PN) is the preferred treatment strategy for SRMs. In centres where LPN is not available, OPN remains considerably more cost-effective than LRN. Furthermore, our study demonstrates that there is no age at which PN is not preferred to LRN. Our study provides additional evidence to advocate PN for the management of all amenable SRMs.

Comprehensive assessment of quality of life and psychosocial adjustment in patients with renal tumors undergoing open, laparoscopic and nephron sparing surgery

PURPOSE

We prospectively evaluated the general and cancer specific quality of life, and psychosocial adjustment of patients with a renal mass treated with radical vs partial nephrectomy via a laparoscopic or an open approach.

MATERIALS AND METHODS

A total of 172 patients with renal tumors completed questionnaires before surgery, and 3 weeks, and 2, 3, 6 and 12 months postoperatively. We assessed general quality of life using SF-36™ and cancer specific quality of life using the Cancer Rehabilitation Evaluation System-Short Form, in addition to intrusive thoughts, avoidance behaviors and fear of recurrence. We used mixed model regression analysis to compare these measures across surgery types during the study course, adjusted for tumor size, histology, stage and renal function.

RESULTS

The SF-36 physical component score differed significantly by surgery type with time (p = 0.04). Patients treated with laparoscopy improved by month 2 while those treated with open surgery had poorer quality of life until month 3. Better cancer specific quality of life was reported in patients who underwent radical vs partial nephrectomy. Age also had a significant effect on outcomes.

CONCLUSIONS

We report one of the most comprehensive patient reported prospective quality of life studies in patients with renal cell carcinoma. There were significant differences in quality of life and psychosocial adjustment outcomes during 1 year among patients treated with 1 of 4 commonly accepted surgical renal procedures. These outcomes must be evaluated in the context of tumor characteristics, cancer specific outcomes and renal function. These quality of life issues may be important to consider when choosing surgical procedures for patients with renal tumors.

Robot-assisted partial nephrectomy: current status, techniques, and future directions

Open partial nephrectomy for the treatment of small renal masses (SRMs) concerning for renal cell carcinoma has been increasingly utilized with the increased incidental detection of SRMs and the growing recognition of the benefits of renal preservation. Laparoscopic partial nephrectomy (LPN) is a minimally invasive technique that achieves comparable oncologic and improved morbidity outcomes when compared to the open procedure. However, LPN is a technically demanding procedure resulting in a long learning curve and a lack of widespread adoption. Robot-assisted partial nephrectomy (RAPN) overcomes many of the technical hurdles of the LPN and is now coming to the forefront for the minimally invasive surgical management of SRMs. To date, the short-term oncologic outcomes of RAPN have been comparable to the open operation while providing the improved morbidity outcomes of LPN. Although encouraging, we await the long-term oncologic results of this new and promising procedure. The current bottleneck is an issue of cost and reliance on a patient-side surgeon. Future developments in instrumentation, newer robots, cost reduction, more streamlined training, increased robotic experience, and adoption by more centers will lead to greater benefit for patients with SRMs requiring nephron-sparing surgery. This review will discuss techniques for RAPN and then delve into the current status of RAPN using parameters such as warm ischemia time, blood loss, hospital stay, oncological outcomes, complications, learning curve, and quality of life. There will be an exploration of potential disadvantages associated with RAPN followed by a look at evolving techniques in regard to this groundbreaking procedure.
