Intraoperative Ultrasound: Bridging the Gap between Laparoscopy and Surgical Precision during 3D Laparoscopic Partial Nephrectomies. Diagnostics (Basel) 2024; 14:942.

Abstract
The use of 3D laparoscopic partial nephrectomy has emerged as a cornerstone in the surgical arsenal for addressing renal tumors, particularly in managing challenging cases characterized by deeply seated tumors embedded within the renal parenchyma. In these intricate scenarios, the utilization of intraoperative ultrasound (IOUS) acquires paramount importance, serving as an indispensable tool for guiding and meticulously monitoring the surgical process in real time. To further explore the efficacy of IOUS-guided techniques, we conducted a retrospective study comparing outcomes in patients who underwent partial nephrectomy with IOUS guidance (n = 60) between 2020 and 2022 with a cohort from 2018 to 2019 without IOUS guidance (n = 25). Our comprehensive analysis encompassed various post-operative parameters, including the duration until food resumption, analgesia requirements, and length of the hospital stay. While these parameters exhibited comparable outcomes between the two groups, notable distinctions emerged in the intraoperative metrics. The IOUS-guided cohort demonstrated significantly reduced blood loss, a shorter median operative duration, and diminished ischemia time (p = 0.001). These compelling findings underscore the undeniable benefits of IOUS-guided techniques in not only facilitating the attainment of negative surgical margins but also in enhancing procedural safety and precision, thereby contributing to improved patient outcomes in the management of renal tumors.

Transperitoneal vs. Retroperitoneal Approach in Laparoscopic Partial Nephrectomy for Posterior Renal Tumors: A Retrospective, Multi-Center, Comparative Study. J Clin Med 2024; 13:701. [PMID: 38337397 PMCID: PMC10856370 DOI: 10.3390/jcm13030701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 01/18/2024] [Accepted: 01/23/2024] [Indexed: 02/12/2024] Open
Abstract
Purpose: The aim of our study is to compare the perioperative, functional, and oncological outcomes of laparoscopic transperitoneal partial nephrectomy (LTPN) and laparoscopic retroperitoneal partial nephrectomy (LRPN) for posterior cT1 renal tumors. Methods: We retrospectively collected data on all patients who consecutively underwent LTPN and LRPN for posterior cT1 renal tumors in three different centers from January 2015 to January 2023. Patients with a single, unilateral, cT1 renal mass, located in the posterior renal surface were included. Patients' data regarding perioperative, functional, and oncological outcomes were collected from medical records and statistically analyzed and compared. Results: A total of 128 patients was obtained, with 53 patients in the LPTN group and 75 patients in the LRPN group. Baseline characteristics were similar. Warm ischemia time (WIT) (18.8 vs. 22.6 min, p = 0.002) and immediate postoperative eGFR drop (-6.1 vs. -13.0 mL/min/1.73 m2, p = 0.047) were significantly lower in the LPTN group. Estimated blood loss (EBL) (100 vs. 150 mL, p = 0.043) was significantly lower in the LRPN group. All other perioperative and functional outcomes and complications were similar between the groups. The positive surgical margin (PSM) rate was lower in the LRPN group, although without statistical significance (7.2% vs. 13.5%, p = 0.258). Surgical success defined by Trifecta (WIT ≤ 25 min, no PSM, and no major postoperative complication) was similar between both approaches. Conclusions: LTPN has significantly shorter WIT and a significantly smaller drop in immediate eGFR when compared to LRPN for posterior renal tumors. On the other hand, LRPN has significantly less EBL than LTPN. LRPN demonstrated fewer PSMs than LTPN, albeit without statistical significance. In terms of overall surgical success, as defined by Trifecta, both approaches achieved similar results.

Abstract
In this study, we investigated the outcomes of laparoscopic approaches for adrenal tumor resection in 67 patients from a single center with a median age of 51 (range 40-79). Predominantly comprising women, the majority of patients were overweight or obese. Adrenal tumors larger than 6 cm were mostly treated using the laparoscopic transperitoneal method (p < 0.001). Our results revealed that patients subjected to the retroperitoneal approach exhibited quicker recovery, as evidenced by faster resumption of oral intake and ambulation, along with reduced intraoperative blood loss and shorter hospitalization (p-value < 0.05). In contrast, patients subjected to the transperitoneal approach experienced minimal complications, though not statistically significant, despite the technique's intricacy and slower recovery. These findings emphasize the significance of tailoring the surgical approach to individual patient characteristics, with particular emphasis on the tumor size. The choice between the retroperitoneal and transperitoneal methods should be informed by patient-specific attributes to optimize surgical outcomes. This study underscores the need for a comprehensive evaluation of factors such as tumor characteristics and postoperative recovery when determining the most suitable laparoscopic approach for adrenal tumor resection. Ultimately, the pursuit of individualized treatment strategies will contribute to improved patient outcomes in adrenal tumor surgery.

Abstract
BACKGROUND AND OBJECTIVE Nephron sparing surgery (NSS) is the preferred management for clinical stage T1 (cT1) renal masses. In recent years, indications have expanded to larger and more complex renal tumors. In an effort to provide optimal patient outcomes, urologists strive to achieve the pentafecta when performing partial nephrectomy. This has led to the continuous technologic advancement and technique refinement including the use of augmented reality, ultrasound techniques, changes in surgical approach and reconstruction, uses of novel fluorescence marker guided imaging, and implementation of early recovery after surgery (ERAS) protocols. The aim of this narrative review is to provide an overview of the recent advances in pre-, intra-, and post-operative management and approaches to managing patients with renal masses undergoing NSS. METHODS We performed a non-systematic literature search of PubMed and MEDLINE for the most relevant articles pertaining to the outlined topics from 2010 to 2022 without limitation on study design. We included only full-text English articles published in peer-reviewed journals. KEY CONTENT AND FINDINGS Partial nephrectomy is currently prioritized for cT1a renal masses; however, indications have been expanding due to a greater understanding of anatomy and technologic advances. Recent studies have demonstrated that improvements in imaging techniques utilizing cross-sectional imaging with three-dimensional (3D) reconstruction, use of color doppler intraoperative ultrasound, and newer studies emerging using contrast enhanced ultrasound play important roles in certain subsets of patients. While indocyanine green administration is commonly used, novel fluorescence-guided imaging including folate receptor-targeting fluorescence molecules are being investigated to better delineate tumor-parenchyma margins. Augmented reality has a developing role in patient and surgical trainee education. While pre-and intra-operative imaging have shown to be promising, near infrared guided segmental and sub-segmental vessel clamping has yet to show significant benefit in patient outcomes. Studies regarding reconstructive techniques and replacement of reconstruction with sealing agents have a promising future. Finally, ERAS protocols have allowed earlier discharge of patients without increasing complications while improving cost burden. CONCLUSIONS Advances in NSS have ranged from pre-operative imaging techniques to ERAS protocols Further prospective investigations are required to determine the impact of novel imaging, in-vivo fluorescence biomarker use, and reconstructive techniques on achieving the pentafecta of NSS.

Abstract
BACKGROUND The debate on whether to choose a transperitoneal (TP) or retroperitoneal (RP) approach for treating upper urinary tract urothelial carcinoma (UTUC) with laparoscopic surgery has been drawing attention. This study aimed to systematically review and meta-analyze the existing evidence regarding oncologic and perioperative outcomes of transperitoneal laparoscopic radical nephroureterectomy (TLNU) and retroperitoneal laparoscopic radical nephroureterectomy (RLNU) in managing UTUC. METHODS A comprehensive literature search was conducted using PubMed, Scopus, Embase, and Google Scholar for identifying randomized controlled trials (RCTs) and observational studies that evaluated the outcomes of TLNU and RLNU for UTUC. Continuous variables were represented by weighted mean difference (WMD) and standard mean difference (SMD), while binary variables were represented by odds ratio (OR), with 95% confidence intervals (CIs). The quality was assessed using the Newcastle-Ottawa scale. A sensitivity analysis was performed to evaluate the robustness of the estimates. RESULT Six observational studies were incorporated into this meta-analysis. The overall TLNU was associated with significantly shorter operating time (WMD - 19.85; 95% CI - 38.03 to - 1.68; P = 0.03); longer recovery time of intestinal function (SMD 0.46; 95% CI 0.08 to 0.84; P = 0.02). However, the terms of estimated blood loss (WMD - 5.72; 95% CI - 19.6 to - 8.15; P = 0.42); length of stay (WMD - 0.35; 95% CI - 1.61 to 0.91; P = 0.59), visual analog pain scale (WMD - 0.38; 95% CI - 0.99 to 0.84; P = 0.22); drainage duration (WMD - 0.22; 95% CI - 0.61 to 0.17; P = 0.26); overall complication rates (OR 1.24; 95% CI 0.58 to 2.63; P = 0.58); local recurrence rate (OR 0.6; 95% CI 0.3 to 1.21; P = 0.16); distant metastasis (OR 0.94; 95% CI 0.04 to 20.77; P = 0.97); 1-year overall survival (OS) (OR 0.45; 95% CI 0.1 to 2.01; P = 0.3) showed no difference between TLNU and RLUN. CONCLUSION TLNU provides similar surgical outcomes and oncologic results compared to RLUN; however, TLNU has a shorter procedure time and prolonged intestinal function recovery time. Due to the heterogeneity among the studies, randomized clinical trials with follow-ups in the long term are required to obtain more definite results.

Abstract
BACKGROUND This study aimed to explore the appropriate location of renal tumors for retroperitoneal approach. MATERIALS AND METHODS We retrospectively analyzed 1040 patients with renal tumor who were treated at our institution from Janurary 2015 to June 2020 and had underwent retroperitoneal robotic assisted-laparoscopic partial nephrectomy (rRAPN). Clinical features and postoperative outcomes were evaluated. RESULTS Patients with incomplete data were excluded, and we included 896 patients in total. The median tumor size was 3.0 (range: 0.8-10.0) cm. The median RENAL Nephrometry Score was 7 (range: 4-11), and the median PADUA Nephrometry Score was 8 (range: 6-14). The median surgical time was 120 min, and the median warm ischemia time was 18 min. The median estimated blood loss was 50 ml. The follow-up time was 20.2 (range: 12-69) months. The mean change of eGFR 1 year after operation was 14.6% ± 19.0% compared with preoperative estimated glomerular filtration rate (eGFR). When compared the tumor at different locations, as superior or inferior pole, anterior of posterior face of kidney, there were no significant differences of intra- and post-operative outcomes such as surgical time, warm ischemia time, estimated blood loss, removal time of drainage tube and catheter, postoperative feeding time and hospital stay, and changes of eGFR one year after surgery. We also compared tumors at special locations as endophytic or exophytic, anterior of posterior hilus of kidney, there were no significant differences in surgical time, warm ischemia time, estimated blood loss and changes of eGFR. There was no significant difference in intraoperative features and postoperative outcomes when tumor larger than 4 cm was located at different positions of kidney. Though the surgical time was longer when BMI ≥ 28 (132.6 min vs. 122.5 min, p = 0.004), no significant differences were observed in warm ischemia time, estimated blood loss, changes in eGFR. Twenty-seven patients (3.0%) had tumor progression, including 8 (0.9%) recurrence, 19 (2.1%) metastasis, and 9 (1.0%) death. CONCLUSION Retroperitoneal approach for RAPN has confirmed acceptable intra- and postoperative outcomes and suits for renal tumors of all different locations. Large tumor size and obesity are not contraindications for rRAPN.

Abstract
Introduction Minimally invasive surgery has been established as the gold standard for the treatment of localised renal tumours. A retroperitoneal approach is a feasible option with advantages in posterior tumours and patients with previous abdominal surgeries. In this context, single-port retroperitoneoscopic partial nephrectomy (SPOR-PN) has not been widely explored and developed. We present this technique's description and our first results. Methods We present a case series of nine patients undergoing SPOR-PN in a single institution. We used a multi-channel single-port access dispositive through a 35 mm incision below the 12th rib, a 30° two-dimensional laparoscope, curved graspers and needle drivers on the left hand and standard rigid material in the right hand. In all surgeries, we performed a complete renorrhaphy with the sliding-clip technique. The pain was evaluated through visual analogue scale (VAS) the day after surgery. Results Patients' age ranged from 44 to 78 years. The median RENAL score was 5p, and the mean surgical time was 134 min. We performed an 'off-clamp' procedure on three patients. Among the patients who had renal artery clamped, the median ischaemia time was 18 min. The median in-hospital stay time was 48 h. Median VAS the day after surgery was 2. None of the anatomical pieces had positive borders. Only one complication was reported (Clavien IIIa). Conclusions SPOR-PN is a feasible minimally invasive and nephron-sparing technique. The advantages of this procedure may not be only a better cosmetic appearance but also less post-operative pain. Further development and larger studies are needed.

Abstract
Objectives: While the choice of surgical approach for laparoscopic nephrectomy is broadly split between transperitoneal and retroperitoneal options, the evidence for the impact of this decision on perioperative outcomes is built on relatively small volume data, with often inconsistent findings and conclusions. We aimed to assess the impact of operative approach on perioperative outcomes for laparoscopic radical, partial and simple nephrectomy and nephroureterectomy through analysis of the British Association of Urological Surgeons (BAUS) Nephrectomy database. Patients and methods: All patients added to the BAUS Nephrectomy database with laparoscopic surgery between 2012 and 2017 inclusively were included and subdivided by operation and surgical approach. Preoperative patient and tumour characteristics, as well as intraoperative and post-operative short-term outcomes, were assessed. Results: Overall, 26,682 operations were documented over the review window (81.6% transperitoneal). Small increases in blood loss ( p = 0.001), transfusion rate ( p = 0.02) and operative length ( p = 0.01) were seen for transperitoneal radical nephrectomies and longer hospital stays seen for retroperitoneal procedures (radical nephrectomy p = 0.00l; partial nephrectomy p = 0.04). Retroperitoneal procedures were associated with increased rates of conversion for simple nephrectomy ( p = 0.02), nephroureterectomy ( p = 0.03) and most notably partial nephrectomy (10.5% versus 4.4%; p = 0.001). No further variation in intraoperative complications, post-operative complications, tumour margin positivity rates, unintended ITU admission, or likelihood of death was identified related to surgical approach. Conclusion: Observed variations in perioperative outcomes were generally modest in nature, and little ground is seen to support a change in operative technique for those committed to one approach. A caveat to this exists with open conversion for retroperitoneal partial nephrectomies and requires careful consideration of patient selection by the individual surgeon. Level of evidence: 4

Abstract
BACKGROUND Moderate-to-severe pain exists in the early postoperative period after laparoscopic renal surgery. OBJECTIVE We investigated the analgesic effect of quadratus lumborum block (QLB) via two approaches in patients undergoing laparoscopic renal nephrectomy. DESIGN A randomised controlled trial. SETTING An academic tertiary care hospital in Beijing, China. PARTICIPANTS Ninety-six patients aged 18 to 70 years who were scheduled for elective laparoscopic radical or partial nephrectomy. INTERVENTIONS Eligible patients were allocated randomly to a control group (no block), lateral QLB group or posterior QLB group. Ultrasound-guided QLB was performed via either the lateral or posterior approach with 30 ml of 0.4% ropivacaine before surgery. MAIN OUTCOME MEASURES The primary outcome was sufentanil equivalent consumption within 24 h. Among secondary outcomes, somatic and visceral pain intensity at rest and on coughing were assessed with a numerical rating scale (where 0 = no pain and 10 = the worst pain) until 24 h postoperatively. RESULTS Sufentanil equivalent consumption did not differ among the three groups (118 ± 36 μg in the control group, 115 ± 47 μg in the lateral QLB group and 119 ± 40 μg in the posterior QLB group; P = 0.955). However, both somatic (lateral QLB vs. control, median difference -1, P < 0.001 at rest and -2 to -1, P < 0.001 on coughing; posterior QLB vs. control, -1, P < 0.001 at rest and -2 to -1, P < 0.001 on coughing) and visceral pain scores (lateral QLB vs. control, -1 to 0, P < 0.001 at rest and -1, P < 0.001 on coughing; posterior QLB vs. control, -1 to 0, P < 0.001 at rest and -2 to -1, P < 0.001 on coughing) were significantly lower in the two QLB groups than in the control group. CONCLUSION For patients undergoing laparoscopic renal surgery, a pre-operative single-shot QLB via the lateral or posterior approach did not decrease opioid consumption, but improved analgesia for up to 24 h after surgery.

Abstract
OBJECTIVES To compare perioperative, oncological and functional outcomes of Laparoscopic Transperitoneal Partial Nephrectomy (LTPN) and Retroperitoneal Laparoscopic Partial Nephrectomy (LRPN) for posterior, cT1 renal masses (RMs). MATERIALS AND METHODS Databases of two urologic institutions applying different laparoscopic surgical approaches on posterior cT1 RMs between June 2016 and November 2018 were retrospectively evaluated. Data on patient demographics, perioperative data and tumor histology were collected and further analyzed statistically. RESULTS Each group consisted of 15 patients. Baseline characteristics were comparable in each group. When compared to LTPN, LRPN was associated with significantly shorter operative time (OT) (115 min versus 199 min, p < 0.05). No significant differences were detected in the other outcomes. CONCLUSIONS LRPN is associated with a significantly shorter OT compared to LTPN for posterior cT1 RMs. Both surgical approaches are safe, feasible and credible, demonstrating optimal results.

Abstract
BACKGROUND Aim of this study was to evaluate and compare perioperative outcomes of transperitoneal (TP) and retroperitoneal (TR) approaches in a multi-institutional cohort of minimally invasive partial nephrectomy (MI-PN). MATERIAL AND METHODS All consecutive patients undergone MI-PN for clinical T1 renal tumors at 26 Italian centers (RECORd2 project) between 01/2013 and 12/2016 were evaluated, collecting the pre-, intra-, and postoperative data. The patients were then stratified according to the surgical approach, TP or RP. A 1:1 propensity score (PS) matching was performed to obtain homogeneous cohorts, considering the age, gender, baseline eGFR, surgical indication, clinical diameter, and PADUA score. RESULTS 1669 patients treated with MI-PN were included in the study, 1256 and 413 undergoing TP and RP, respectively. After 1:1 PS matching according to the surgical access, 413 patients were selected from TP group to be compared with the 413 RP patients. Concerning intraoperative variables, no differences were found between the two groups in terms of surgical approach (lap/robot), extirpative technique (enucleation vs standard PN), hilar clamping, and ischemia time. Conversely, the TP group recorded a shorter median operative time in comparison with the RP group (115 vs 150 min), with a higher occurrence of intraoperative overall, 21 (5.0%) vs 9 (2.1%); p = 0.03, and surgical complications, 18 (4.3%) vs 7 (1.7%); p = 0.04. Concerning postoperative variables, the two groups resulted comparable in terms of complications, positive surgical margins and renal function, even if the RP group recorded a shorter median drainage duration and hospital length of stay (3 vs 2 for both variables), p < 0.0001. CONCLUSIONS The results of this study suggest that both TP and RP are feasible approaches when performing MI-PN, irrespectively from tumor location or surgical complexity. Notwithstanding longer operative times, RP seems to have a slighter intraoperative complication rate with earlier postoperative recovery when compared with TP.

Abstract
BACKGROUND Surgical approaches to the kidneys and perirenal structures are uncommonly performed in horses and several complications have been described with the current procedures. OBJECTIVE To describe the anatomy of the retroperitoneal perirenal space and investigate a retroperitoneal minimally invasive approach to access the kidney and perirenal structures in horses. STUDY DESIGN Descriptive, cadaveric study. METHODS Anatomical description of the retroperitoneal space was performed on three equine cadavers and the surgical approach was developed based on these dissections. Ten cadaveric horses underwent a retroperitoneoscopy. Five horses were placed in a right lateral recumbency position to explore the left retroperitoneal space and five horses were placed in a standing position to explore both left and right sides. Anatomical landmarks, working space and access to the renal hilus and perirenal structures were evaluated. RESULTS Dissections revealed that kidneys are surrounded by a renal fascia which delimits two spaces: a perirenal space between the kidney and the renal fascia, and a pararenal space between the renal fascia and psoas muscles or peritoneum. The retroperitoneoscopic portal was placed at the level of the dorsal aspect of the tuber coxae, 3 cm caudal to the last rib for the left side and 2 cm caudal to the last rib for the right side. Retroperitoneal access and working space were successfully established in all horses. The standing position allowed an easier dissection than lateral recumbency. Division of the perirenal fat allowed access to the kidney and adrenal glands as well as individualisation of renal vessels and ureter in the renal hilus. MAIN LIMITATIONS Study of cadavers precluded appreciation of haemorrhage or use the pulsating vessels as landmarks. CONCLUSIONS This study provides a description of the retroperitoneal perirenal space and describes a new surgical approach to access kidneys and perirenal structures in horses.

Abstract
OBJECTIVE The aim of this study is to assess the safety and feasibility of the transperitoneal laparoscopic approach during nephron sparing surgery in patients with previous abdominal surgery. PATIENTS AND METHODS We retrospectively analyzed patients undergoing transperitoneal laparoscopic partial nephrectomy for renal masses. All patients had received a diagnosis of cT1a renal exophytic mass (⩽5 cm). Patients were divided into two groups, those with and without previous abdominal surgery. Patients with solitary kidney or major previous abdominal surgery were excluded in this study. The operative time, estimated blood loss, length of stay, surgical complications, and positive surgical margins were recorded to compare outcomes among two groups. RESULTS Of the 157 patients who were included in our study, 71 (45.3%) had a history of abdominal surgery (Group 1), while the remaining 86 (54.7%) had not (Group 2). Cholecystectomy was the most common previous surgery performed near the renal fossa. Patients with previous abdominal surgery experienced increased operative time (111.5 vs 83.2 min; p = 0.001). However, no statistically significant difference was found in estimated blood loss (122.1 vs 114.4 mL; p = 0.363), length of stay (4.1 vs 3.8 days; p = 0.465), rate of conversion to open surgery (2.8% vs 2.3%; p = 0.234), and rate of complications (p = 0.121). However, operative time (p = 0.003) and length of stay (p < 0.001) were greater in patients with versus those without previous open cholecystectomy. CONCLUSION Our results suggest that laparoscopic partial nephrectomy after minor previous abdominal surgery is safe and feasible in selected patients affected by renal masses with low nephrometry score. However, previous cholecystectomy results in an increased risk of conversion to open surgery and longer hospital stay in patients undergoing right laparoscopic partial nephrectomy.

Abstract
Background: Surgical management of complicated retroperitoneal mass is one of the most challenging urologic oncologic surgeries. This study aims to describe our technique and experience in dealing with retroperitoneal mass. Methods: Three patients with complicated retroperitoneal mass were treated with robot-assisted surgery with four arms through retroperitoneal approach. Surgical Procedure: Our standardized anatomic-based "kidney safe first, then mass resection" technique for robot-assisted complicated retroperitoneal mass resection focused on minimizing the chance of renal pedicle injury. Baseline demographics, pathology data, and latest follow-up outcome were obtained. Results: In this retrospectively reviewed case series, all 3 patients were successfully treated with robot-assisted surgery with four arms during retroperitoneal space. One patient received paravertebral mass resection 2 weeks after the robotic surgery. Mean data included operative time of 175 minutes, estimated blood loss was 133 mL, and hospital stay was 4 days. No complications occurred. Conclusions: Robot-assist surgery for complicated retroperitoneal mass with four arms is a safe and feasible way. Patient Summary: Mini-invasive treatment for retroperitoneal mass with robotic four arms through retroperitoneal approach is a feasible way. The approach reduces interruption of intracorporeal structure and organs. And patients could benefit from the retroperitoneal approach with a quicker recovery.

BMC Anesthesiol 2019; 19:186. [PMID: 31627728 PMCID: PMC6800496 DOI: 10.1186/s12871-019-0850-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2019] [Accepted: 09/13/2019] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Ultrasound-guided lateral transversus abdominis plane (TAP) block can provide definite analgesia to the anterior abdominal wall. However, whether this method is useful in renal surgery through the lateral abdominal wall pathway remains unknown. The study aimed to evaluate the analgesic efficacy of lateral TAP block for retroperitoneoscopic partial or radical nephrectomy. METHOD In this prospective, randomized, double-blind, placebo-controlled trial, eligible patients were randomized into two groups. After anaesthesia induction, ultrasound-guided lateral TAP block was performed with either 30 ml of 0.4% ropivacaine (Group T) or an equivalent volume of normal saline (Group C). The primary outcomes were opioid consumption during surgery and in the first 24 h after surgery. Secondary outcomes included postsurgical pain intensity immediately awakening from anaesthesia and at 0.5, 1, 2, 6, 12, and 24 h after surgery, as well as recovery variables including the incidence of postoperative nausea and vomiting (PONV), sleep quality, time to first ambulation, drainage and length of hospital stay. RESULTS A total of 104 patients were enrolled and randomized (53 in Group T and 51 in Group C). Laparoscopic surgery was converted to open surgery in one patient of Group T; this patient was excluded from the outcome analysis. The opioid consumption during surgery (intravenous morphine equivalent dose: median 35.0 mg [interquartile range 18.0, 49.6] in Group C vs. 40.3 mg [20.9, 59.0] in Group T, P = 0.281) and in the first 24 h after surgery (10.8 mg [7.8, 21.7] in Group C vs. 13.2 mg [8.0, 26.6] in Group T, P = 0.311) did not differ significantly between groups. There were no significant differences between groups regarding the pain intensity at all time points after surgery and the recovery variables (all P > 0.05). CONCLUSIONS Our results showed that, in patients undergoing retroperitoneoscopic renal surgery, preoperative lateral TAP did not decrease intra- and postoperative opioid consumption, nor did it relieve pain intensity or promote postoperative recovery in the first 24 h after surgery. However, the trial might be underpowered. TRIAL REGISTRATION This study was registered on November 4, 2017, in the Chinese Clinical Trail Registry with the identification number ChiCTR-INR-17013244 .

Abstract
Renal cell carcinoma (RCC) is extremely rare in pregnant women. However, this is one of the most reported urologic tumors during pregnancy. The aim of this review was to evaluate RCC during pregnancy in terms of epidemiology, risk factors, diagnosis, natural history of disease, and the safety of laparoscopic approach in the management of this tumor. RCC presentation is frequently made incidentally during an ultrasonography performed for other reasons, such as hydronephrosis owing to non-neoplastic causes. The optimal time for surgery during pregnancy and the consequences of surgery on the maternal and fetal well-being are major considerations. Risks for adverse pregnancy outcomes should be explained, and the patient's decision about pregnancy termination should be considered. Ultrasound is good in diagnosing renal masses, with a sensitivity comparable to that of computed tomography only for exophytic masses larger than 3 cm. Magnetic resonance imaging is reproducible and a good, though expensive, alternative to computed tomography scans for the evaluation of renal lesions in pregnant women. Radical nephrectomy or nephron-sparing surgery are essential treatments for management of RCC. Laparoscopic surgery has historically been considered dangerous during pregnancy and avoided whenever possible, because of concerns regarding surgery-related risks, such as uterine injury, miscarriage, teratogenesis, preterm birth, and hypercapnia. The laparoscopic treatment during pregnancy is becoming increasingly accepted where feasible with low morbidity. However, the combination of a multidisciplinary approach, multi-specialty communication, and skilled surgeons can give the best possible outcomes for mother and fetus.

Abstract
Objectives: To summarize the value and application experiences of intraoperative laparoscopic ultrasonography (ILUS) in retroperitoneal laparoscopic partial nephrectomy (RLPN). Materials and Methods: From January 2013 to December 2018, RLPN with ILUS was performed on the recent 199 patients in our center (two patients received bilateral RLPN due to suspected malignancy of both right and left sides), and the relevant clinical and follow-up data were retrospectively reviewed. Among them, 119 patients were male and 80 were female; the age of patients was 53.4 ± 12.3 years. Of all the renal tumors, 105 were located on the left side and 96 on the right side with a RENAL score of 6.6 ± 1.7. All the patients were diagnosed as or suspected of having a renal tumor by preoperative imaging examination. The ILUS was applied in all the operations to help locate the tumor, delineate the boundary, clarify the diagnosis, observe the blood supply, and so on. Results: RLPN with ILUS in these 199 patients was successfully performed without conversion to open surgery. All surgeries were completed in 90.2 ± 21.7 min, with 73.6 ± 89.2 mL for estimated blood loss, and 19.3 ± 5.6 min for warm ischemia time. The tumor size was 3.6 ± 1.5 cm, and all the surgical margins were negative. The drainage days and postoperative hospital days were 4.7 ± 2.3 and 6.1 ± 2.3, respectively. The preoperative creatinine was 69.7 ± 19.4 μmol/L compared with 61.6 ± 12.7 μmol/L measured 1 month postoperatively. There were 17 cases of renal cell carcinoma no more than 1 cm, and they were resected without artery clamp or a large amount of blood loss. Satellite tumors were confirmed in 12 cases, of which 8 were not detected by preoperative examinations and finally found by ILUS during surgeries. Conclusion: ILUS can alleviate the difficulty of preoperative diagnosis, facilitate surgical dissection, and improve the effect of nephron-sparing surgeries. Due to its great advantage, ILUS should further be promoted and applied.

Abstract
RATIONALE Hydronephrosis caused by retroperitoneal hematoma after a seatbelt injury is a unique clinical entity. PATIENT CONCERNS A 21-year-old man, who had been wearing a seatbelt, was brought to our hospital after a motor vehicle collision, complaining of abdominal pain. Computed tomography (CT) revealed retroperitoneal hematoma in the upper pelvic region. Since he was hemodynamically stable throughout admission, he was managed conservatively. Seventeen days after initial discharge, the patient revisited our emergency department due to right back pain. DIAGNOSES CT scans indicated retroperitoneal hematoma growth resulting in hydronephrosis of the right kidney. INTERVENTIONS Laparoscopic drainage of the retroperitoneal hematoma was successfully performed. OUTCOMES His symptoms resolved after the surgery. Follow-up CT scans three months later demonstrated complete resolution of the hydronephrosis and retroperitoneal hematoma. LESSONS Our case highlights a patient with delayed hydronephrosis because of retroperitoneal hematoma expansion after a seatbelt injury.

Abstract
Objective To evaluate the feasibility and efficacy of intraoperative ultrasonography in laparoscopic partial nephrectomy (LPN) for intrarenal tumors. Patients and methods All patients who underwent LPN for renal tumors in our institution from January 2010 to October 2016 were assessed retrospectively. Patients were divided into two groups, the first with totally intrarenal tumors (TIT group), defined as a solid renal mass with no exophytic element on both preoperative and intraoperative evaluations, and the second with exophytic tumors (control group). General information and perioperative data of the two groups were compared, including tumor characteristics, operative time, estimated blood loss, warm ischemia time and pathological findings. Intraoperative laparoscopic ultrasonography (ILUS) was used to precisely locate and delineate the TIT border, as well as seeking for other suspected lesions. Results We identified 583 patients who underwent LPN in our center, including 46 in the TIT and 537 in the control group. All patients in the TIT group were evaluated by ILUS, and all TIT procedures were successfully performed with only one conversion to open surgery. The mean tumor sizes in the TIT and control groups were 2.42 ± 0.46 cm and 3.29 ± 1.43 cm (p < 0.001), respectively. The TIT group’s R.E.N.A.L. nephrometry score was higher than that of the control group (median 8.5 vs 6.0, p < 0.001), and their mean operation times were 127.2 ± 16.0 min and 120.1 ± 19.2 min, respectively. Mean estimated blood loss was higher in the TIT than in the control group (161.3 ml vs 136.6 ml, p = 0.003). Mean warm ischemia time differed in the TIT and control groups (22.2 ± 6.4 vs 20.6 ± 4.7 min, p = 0.105), but not significantly. Rates of open conversion and positive margins, as well as rates of major postoperative complications, pathological findings, and 1-month changes in renal function, were similar in the two groups. Conclusion Intraoperative ultrasonography is technically feasible in patients undergoing LPN for TITs. This method may reduce the need for radical nephrectomy in patients with endogenic renal masses.

Abstract
Nonmodifiable factors including pre-operative renal function and amount of healthy renal tissue preserved are the most important predictive factors that determine renal function after partial nephrectomy. Ischaemia time is an important modifiable risk factor and cold ischaemia time should be used if longer ischaemia time is anticipated. New techniques may have a role in maximising postoperative kidney function, but more robust studies are required to understand their potential benefits and risks.

Abstract
Objective To develop and describe a laparoscopic retroperitoneal access technique, investigate working space establishment, and describe the surgical anatomy in the retroperitoneal space as an initial step for clinical application of retroperitoneal laparoscopy in dogs. Study Design Cadaveric and experimental study. Animals Cadaveric (n=8) and healthy (n=6) adult dogs. Methods The retroperitoneal access technique was developed in 3 cadavers based on the human technique and transperitoneal observation. Its application and working space establishment with carbon dioxide (CO2) insufflation alone was evaluated in 5 cadavers by observing with a transperitoneal telescope and in 6 live dogs by repeated computed tomography (CT) scans at pressure of 0, 5, 10, and 15 mmHg. Recordings of retroperitoneoscopy as well as working space volume and linear dimensions measured on CT images were analyzed. Results Retroperitoneal access and working space establishment with CO2 insufflation alone were successfully performed in all 6 live dogs. The only complication observed was in 1 dog that developed subclinical pneumomediastinum. As pressure increased, working space was established from the ipsilateral to the contralateral side, and peritoneal tearing eventually developed. Working space volume increased significantly from 5 mmHg and linear dimensions increased significantly from 0 to 10 mmHg. With pneumo‐retroperitoneum above 5 mmHg, retroperitoneal organs, including kidneys and adrenal glands, were easily visualized. Conclusion The retroperitoneal access technique and working space establishment with CO2 insufflation starting with 5 mmHg and increasing to 10 mmHg provided adequate working space and visualization of retroperitoneal organs, which may allow direct access for retroperitoneal laparoscopy in dogs.

Abstract
OBJECTIVE To evaluate the feasibility of Hem-o-lok clips tied with threads to improve surgical view in retroperitoneal laparoscopic surgery for renal cell carcinoma. MATERIALS AND METHODS Laparoscopic radical and partial nephrectomies performed by a single surgeon from May 2013 to April 2015 were reviewed. If Hem-o-lok clips tied with threads were applied to improve surgical view, the patient was recruited to the Hem-o-lok group. The other patients were recruited to the control group. Patient information, time of exposure procedure, number of clips used, number of trocars, exposure satisfaction, operation time, estimated blood loss, and perioperative complications were recorded. RESULTS Sixty-eight laparoscopic radical/partial nephrectomies were performed by a single surgeon. For 31 cases, Hem-o-lok clips were tied with threads to improve surgical view. For the other 37 cases, no Hem-o-lok clips were used. All cases were successfully performed. It took 30 to 178 seconds to finish the exposure procedure. In the Hem-o-lok group, less trocar usage, shorter operation time, and better exposure satisfaction were observed than control group (P < .05). CONCLUSIONS This new technique is feasible and easy to improve surgical view in retroperitoneal laparoscopic surgery for renal cell carcinoma. This technique may be helpful to shorten operation time and avoid the use of the fourth trocar in certain cases. Large scale randomized controlled studies are needed to further prove its efficiency.

Abstract
Background Among the different organs used for NOTES (natural orifice translumenal endoscopic surgery) technique, the transvaginal approach may be the optimal choice because of a simple and secure closure of colpotomy site. Pure and hybrid NOTES transvaginal operations were routinely performed via transperitoneal access. In this study, we investigate the safety and feasibility of pure retroperitoneal natural orifice translumenal endoscopic surgery (NOTES) transvaginal nephrectomy using conventional laparoscopic techniques in a porcine model. Methods Six female pigs, weighing an average of 30 kg, were used in this study. Under general anesthesia, pure retroperitoneal NOTES transvaginal nephrectomy was conducted using standard laparoscopic instruments. Posterolateral colpotomy was performed, and the incision was enlarged laterally using blunt dissection and pneumatic dilation. A single-port device was inserted to construct the operative channel. The retroperitoneal space was created using sharp and blunt dissection under endoscopic guidance up to the level of the kidney. Dissection and removal of the kidney were performed according to standard surgical procedure, and the colpotomy site was closed using interrupted sutures. The survival and complications were observed 1 week postoperatively. Results Our results showed that two cases failed because of peritoneal rupture. One case was successful, but required the assistance of an extra 5 mm laparoscopic trocar inserted in the flank. Three cases of pure retroperitoneal NOTES transvaginal nephrectomy were completed, and survived 1 week after the operation. In these three cases, no intra- or postoperative complications were observed. Conclusions All findings confirmed the safety and feasibility of the retroperitoneal pure retroperitoneal NOTES transvaginal nephrectomy using standard laparoscopic instruments, which suggested the possibility of clinical application in human beings in the future.

Abstract
AIM: To evaluate outcomes of robotic-assisted laparoscopic partial nephrectomy performed for posterior renal tumors via a transperitoneal or retroperitoneal approach.
METHODS: Retrospective review was performed for patients who underwent robotic-assisted laparoscopic partial nephrectomy (RALPN) for a posterior renal tumor between 2009-2015. Patient demographic characteristics, operative factors, pathology, oncologic outcomes, renal function, and tumor complexity were obtained. Radius of the tumor, exophytic/endophytic properties of the tumor, nearness of tumor to the collecting system, anterior/posterior position, location relative to the polar line (RENAL) nephrometry scores were calculated. nephrometry scores were calculated. The operative approach was determined by the primary surgeon.
RESULTS: A total of 91 patients were identified who underwent RALPN for a posterior renal tumor. Fifty-four procedures were performed via the retroperitoneal (RP) approach, and 37 via the transperitoneal (TP) approach. There were no significant differences in patient factors (race, sex, age and body mass index), RENAL nephrometry scores, tumor size, conversion rates, or margin status. Among procedures performed on-clamp, there was no significant difference in warm ischemia times. Total operative time (180.7 min for RP vs 227.8 min for TP, P < 0.001), robotic console time (126.9 min for RP vs 164.3 min for TP, P < 0.001), and median estimated blood loss (32.5 mL for RP vs 150 mL for TP, P < 0.001) were significantly lower via the RP approach. Off-clamp RALPN was performed for 31 (57.4%) of RP procedures vs 9 (24.3%) of TP procedures. Oncologic and renal functional outcomes were equivalent.
CONCLUSION: The RP approach to RALPN for posterior renal tumors is superior with regard to operative time and blood loss and the ability to be performed off-clamp.

Abstract
Nephrectomy is, perhaps, one of the techniques in which laparoscopic approach has been widely used. It has quickly evolved since Clayman introduced it in 1990 with a renal tumor. Since then, its goodness has been extrapolated to most entities that require surgical removal of the kidney. We review the current most discussed aspects referred to the main laparoscopic nephrectomy techniques (simple nephrectomy, nephroureterectomy, radical, and nephron-sparing nephrectomy) and particularities of this approach.

Abstract
INTRODUCTION Retroperitoneal partial nephrectomy has not been studied as a surgical approach for children with bilateral Wilms tumor. There are advantages to this technique, including isolation of urine leaks to the retroperitoneum, decreased risk of bowel injury, and decreased time to resuming a diet. Presently, all bilateral Wilms tumors are treated with neoadjuvant chemotherapy and attempted nephron-sparing surgery. In this study, we compare the outcomes of the retroperitoneal and transabdominal approaches in doing partial nephrectomy for bilateral Wilms tumor. METHODS With the institutional review board approval, we reviewed records of 14 pediatric patients with metachronous or synchronous bilateral Wilms tumors who underwent surgery after chemotherapy between 1994 and 2014. Only operative procedures with the intent to cure were included (n=15) and of these, 5 procedures were retroperitoneal and 10 were transabdominal in approach. Individual kidneys operated upon (n=26) were analyzed using the preoperative radius exophytic/endophytic nearness anterior/posterior location nephrometry score to ensure that resected tumors were comparable between the two surgical groups. Charts were retrospectively analyzed for intraoperative parameters and postoperative course. Differences between parameters were evaluated using Mann-Whitney and chi-square tests. RESULTS Resected tumors in both surgical treatment groups had comparable sizes, nephrometry scores, and rates of anaplasia. Operative time, blood loss, and transfusion requirement were similar between the two groups. The extent of lymph node sampling and rates of R0 resection were equivalent. One adverse intraoperative event, a bowel enterotomy, was seen in the transabdominal group. Patients after retroperitoneal partial nephrectomy required half the time to return to an oral diet as compared with those after a transabdominal surgery, approaching statistical significance (p=0.08). Rates of the postoperative urine leak were similar, though two in the transabdominal group required reoperation for drainage. There were four recurrences, all in the transabdominal group. CONCLUSION Our experience demonstrates that the retroperitoneal approach is equivalent to the transabdominal technique with regards to intraoperative complications, lymph node dissection, and R0 resection. Advantages include less time to resumption of oral feeding, decreased risk of bowel injury, and isolation of urine leaks to the retroperitoneum. It should be considered a viable surgical option in the treatment of bilateral Wilms tumors.

Abstract
PURPOSE To evaluate the validity of hand-assisted laparoscopic partial nephrectomy (HALPN) for small renal masses, patients who underwent HALPN, robot-assisted laparoscopic partial nephrectomy (RALPN), or open partial nephrectomy (OPN) at a single medical institution were compared in terms of perioperative outcomes. PATIENTS AND METHODS In this retrospective cohort study, all 590 consecutive patients who underwent HALPN (n=89), RALPN (n=147), or OPN (n=354) between July 2011 and April 2014 in a single institute were compared in terms of perioperative outcomes, including the mean operative time, warm ischemia time (WIT), length of the hospital stay, change in the estimated glomerulofiltration rate (eGFR), duration of analgesic use, surgical margins, and adverse events. The patient groups were compared by a multivariate regression model, in which adjustments were made for differences in baseline demographic and tumor characteristics. RESULTS OPN associated with a significantly longer mean operative time (187 minutes) than RALPN (162 minutes; p<0.001) or HALPN (172 minutes; p=0.013), a longer hospital stay (7.3, 5.3, and 5.9 days, respectively; p<0.001 and <0.001, respectively), and a longer duration of analgesic use (6.6, 4.6, and 5.4 days, respectively; p<0.001 and <0.001, respectively). HALPN and RALPN were equivalent in terms of operative time. RALPN had a significantly longer WIT than HALPN and OPN (p<0.001 and <0.001, respectively). HALPN had a significantly longer hospital stay than RALPN (p=0.026). The three methods differed in terms of eGFR change (p=0.028), but multivariate analysis found that the surgical method was not a significant factor for eGFR. The three methods did not differ in terms of complication rates. CONCLUSIONS HALPN associated with shorter operative and convalescence times compared with OPN. HALPN was generally not inferior to RALPN in terms of perioperative outcomes, although it associated with a longer convalescence.

Abstract
Objectives: To compare the treatment of laparoscopic (LPN) versus open partial nephrectomy (OPN) in patients with multilocular cystic renal cell carcinoma (MCRCC). Methods: Thirty-seven patients diagnosed with MCRCC were reviewed retrospectively between January 2007 and January 2013 at our institution. They were divided into two groups: group 1 (LPN) consisted of 19 patients (51.4%) and group 2 (OPN) of 18 patients (48.6%). RENAL and the Preoperative Aspects and Dimensions Used for an Anatomical classification were applied to predict perioperative complications, which were graded based on the Clavien-Dindo classification. Results: The two groups were comparable with regard to all of the patients' baseline characteristics. In group 1, the mean operative time was 142.1 min, including the mean warm ischemia time (WIT) of 32.6 min; the mean estimated blood loss (EBL) was 96.1 ml, the mean retroperitoneal drainage lasted 3.6 days, and the mean postoperative hospital stay was 5.3 days. In group 2, the figures were 126.6 and 23.5 min, 223.3 ml, and 4.6 and 8.7 days, respectively. The differences in WIT, EBL, drainage days and hospitalization were statistically significant between both groups (p < 0.05). No recurrence or new lesions occurred in these patients during a mean follow-up of 37.8 months. Conclusions: Our single-center experience suggests that although it remains technically complex, demanding and challenging for MCRCC, LPN can still induce favorable perioperative results and survival rates in MCRCC are comparable with OPN.
