[PMID: 38614921 DOI: 10.1016/j.urolonc.2024.03.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 01/16/2024] [Accepted: 03/06/2024] [Indexed: 04/15/2024]
Abstract
INTRODUCTION Delayed bleeding is a potentially serious complication after partial nephrectomy (PN), with reported rates of 1%-2%. Patients with multiple renal tumors, including those with hereditary forms of kidney cancer, are often managed with resection of multiple tumors in a single kidney which may increase the risk of delayed bleeding, though outcomes have not previously been reported specifically in this population. The objective of this study was to evaluate the incidence and timing of delayed bleeding as well as the impact of intervention on renal functional outcomes in a cohort primarily made up of patients at risk for bilateral, multifocal renal tumors. METHODS A retrospective review of a prospectively maintained database of patients with known or suspected predisposition to bilateral, multifocal renal tumors who underwent PN from 2003 to 2023 was conducted. Patients who presented with delayed bleeding were identified. Patients with delayed bleeding were compared to those without. Comparative statistics and univariate logistic regression were used to determine potential risk factors for delayed bleeding. RESULTS A total of 1256 PN were performed during the study period. Angiographic evidence of pseudoaneurysm, AV fistula and/or extravasation occurred in 24 cases (1.9%). Of these, 21 were symptomatic presenting with gross hematuria in 13 (54.2%), decreasing hemoglobin in 4(16.7%), flank pain in 2(8.3%), and mental status change in 2 (8.3%), while 3 patients were asymptomatic. Median number of resected tumors was 5 (IQR 2-8). All patients underwent angiogram with super-selective embolization. Median time to bleed event was 13.5 days (IQR 7-22). Factors associated with delayed bleeding included open approach (OR 2.2, IQR(1.06-5.46), P = 0.04 and left-sided surgery (OR 4.93, IQR(1.67-14.5), P = 0.004. Selective embolization had little impact on ultimate renal functional outcomes, with a median change of 11% from the baseline eGFR after partial nephrectomy and embolization. One patient required total nephrectomy for refractory bleeding after embolization. CONCLUSIONS Delayed bleeding after PN in a cohort of patients with multifocal tumors is an infrequent event, with similar rates to single tumor series. Patients should be counseled regarding timing and symptoms of delayed bleeding and multidisciplinary management with interventional radiology is critical for timely diagnosis and treatment.

Robotic partial nephrectomy is associated with a significantly decreased rate of postoperative pseudoaneurysm compared to open and laparoscopic partial nephrectomy. J Robot Surg 2024; 18:241. [PMID: 38833079 DOI: 10.1007/s11701-024-01999-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Accepted: 05/27/2024] [Indexed: 06/06/2024]
Abstract
While partial nephrectomy offers oncologic efficacy and preserves renal function for T1 renal tumors, renal artery pseudoaneurysm (RAP) remains a rare but potentially life-threatening complication. This study compared RAP incidence across robotic-assisted (RAPN), laparoscopic (LPN), and open (OPN) partial nephrectomies in a large tertiary oncological center. This retrospective study analyzed 785 patients undergoing partial nephrectomy between 2012 and 2022 (398 RAPN, 122 LPN, 265 OPN). Data included demographics, tumor size/location, surgical type, clinical presentation, treatment, and post-operative outcomes. The primary outcome was RAP incidence, with secondary outcomes including presentation, treatment efficacy, and renal function. Seventeen patients (2.1%) developed RAP, presenting with massive hematuria (100%), hemorrhagic shock (5.8%), and clot retention (23%). The median onset was 12 days postoperatively. RAP occurred in 4 (1%), 4 (3.3%), and 9 (3.4%) patients following RAPN, LPN, and OPN, respectively (p = 0.04). Only operative length and surgical approach were independently associated with RAP. Selective embolization achieved immediate bleeding control in 94%, with one patient requiring a second embolization. No additional surgery or nephrectomy was needed. Estimated GFR at one year was similar across both groups (p = 0.53). RAPN demonstrated a significantly lower RAP incidence compared to LPN and OPN (p = 0.04). Emergency angiographic embolization proved effective, with no long-term renal function impact. This retrospective study lacked randomization and long-term follow-up. Further research with larger datasets and longer follow-ups is warranted. This study suggests that robotic-assisted partial nephrectomy is associated with a significantly lower risk of RAP compared to traditional approaches. Emergency embolization effectively treats RAP without compromising long-term renal function.

Impact of renal sinus protrusions on achieving trifecta in robot-assisted partial nephrectomy. BJUI COMPASS 2023; 4:584-590. [PMID: 37636206 PMCID: PMC10447216 DOI: 10.1002/bco2.244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 02/27/2023] [Accepted: 04/16/2023] [Indexed: 08/29/2023] Open
Abstract
Objective The objective of this work is to assess the relationship between the morphological characteristics of a central tumour and the perioperative outcomes of robot-assisted partial nephrectomy (RAPN). Subjects and Methods We retrospectively analysed the data from 186 patients with central tumours involving the renal sinus, who underwent RAPN in a single-centre study between February 2015 and June 2022. All cases were assigned a RENAL nephrometry score based on preoperative images. The shape of the protruding portion of the tumour was classified into four types: 'flat', 'spherical', 'single-hump', and 'complex-hump', and was independently assessed by two readers. The trifecta is defined as the warm ischemia time within 25 min, negative surgical margins, and no major postoperative complications. Univariate and multivariate analyses were performed to identify the factors associated with the failing trifecta. Results Trifecta was achieved in 113 cases (60.8%), and the achievement rate in flat, spherical, single-hump, and complex-hump types was 83.3%, 74.5%, 64.3%, and 21.3%, respectively. Prolonged warm ischemia time was the primary cause of the failure to achieve the trifecta. The rate of positive surgical margins and upstage to pathological T3a was greater for complex humps while the rate of major complications and postoperative GFR preservation did not differ between shapes. On multivariate analysis for failing trifecta achievement, the complex-hump protrusion was found to be an independent positive predictor (odds ratio: 15.8; p < 0.001), whereas the height and width of protrusion were not significantly related. Conclusions The degree of difficulty varied among central tumours, and it was not possible to precisely measure it with existing scoring systems. Complex-hump protrusions strongly correlate with failure to achieve the trifecta. Preoperative assessment of the morphology of protrusion is useful for predicting outcomes.

Abstract
The application and prognostic nature of systemic inflammatory reaction syndrome (SIRS) is still being researched, as using SIRS parameters to predict patient status is cheap, efficient, fast, and easy. The study aimed to determine SIRS markers and postoperative complications occurrence in patients undergoing kidney tumor surgery, and to verify if SIRS occurrence depends on age, sex, BMI (body mass index), comorbidities, patients' general condition before the surgery, type of surgery, intraoperative blood loss, or intraoperative ischemia time. Body temperature, heart rate, respiratory rate, and leukocyte count were measured in patients (n = 285) operated on due to a kidney tumor on the first (T0) and third (T3) postoperative day. Univariable and multivariable logistic regression were used to analyze the factors affecting postoperative SIRS and complications occurrence. T0: SIRS developed in patients with higher BMI, >2 ASA points, and more substantial intraoperative blood loss. T3: SIRS developed in obese or overweight patients, with >2 ASA points, significantly higher relative HR change, lower relative body temperature change, respiratory rate, and leukocyte count. BMI values, preoperative general health status, and the amount of intraoperative blood loss in patients undergoing surgery due to a kidney tumor can contribute to SIRS occurrence. Patient's sex, age, tumor size, type of surgery, operated side, and time of intraoperative ischemia do not affect SIRS occurrence.

Abstract
Background A renal artery aneurysm is a rare clinical presentation that can be found incidentally on imaging or during workup for refractory hypertension. Its presentation can be similar to that of a renal artery pseudoaneurysm, but the etiologies of the two vascular lesions differ. We present a patient who had an incidental finding of a large renal artery aneurysm that was managed with endovascular embolization. We also describe the literature surrounding the etiology, presentation and management of both renal artery aneurysms and renal artery pseudoaneurysms. Case presentation A 62-year-old man was referred to a urologic oncologist for workup of a newly found renal mass. Initial imaging with computed tomography showed a homogenous, well-circumscribed mass arising from the right kidney. Further evaluation with Doppler ultrasonography demonstrated pulsatile flow within the renal mass that was concerning for a renal artery pseudoaneurysm. The patient initially underwent a diagnostic angiogram by interventional radiology and was found to have a true renal artery aneurysm. Interventional radiology considered placement of a covered stent or angioembolization, but treatment was deferred due to concern for compromising the patient’s renal function. Patient was subsequently transferred to a neighboring hospital for management by vascular surgery. After considering both open surgical and endovascular approaches, the patient ultimately underwent angioembolization of the renal artery aneurysm. Short-term follow-up showed successful exclusion of the aneurysm with minimal adverse effects to the patient. Conclusions Our case report documents a unique case of an incidentally found large renal artery aneurysm that was successfully managed with endovascular embolization. Renal artery aneurysms and renal artery pseudoaneurysms, which can present similarly on imaging, are important diagnostic considerations in a patient presenting with a new renal mass. While open surgical approaches can be used to repair aneurysms, endovascular approaches using stenting or angioembolization are safe and effective options for treating renal aneurysms and renal pseudoaneurysms.

Mid-term outcome of transarterial embolization of renal artery pseudoaneurysm and arteriovenous fistula after partial nephrectomy screened by early postoperative contrast-enhanced CT. CVIR Endovasc 2020; 3:68.

Abstract
Purpose To retrospectively evaluate the mid-term outcome of transarterial embolization (TAE) of renal artery pseudoaneurysm (RAP) including arteriovenous fistula (AVF) after partial nephrectomy screened by early postoperative contrast-enhanced CT (CE-CT). Materials and methods Eighty-two patients (7.0%) who underwent TAE after partial nephrectomy were reviewed, from 1166 partial nephrectomies performed over 6 years. In 18 patients (22.0%), TAE was performed emergently on the median postoperative day (POD) seven. In the remaining patients, elective TAE was performed on the median POD six for RAP detected by early postoperative CE-CT or that emerged on follow-up CE-CT. Results In one patient (1.2%), TAE was performed twice because one of two RAPs could not be embolized during the first TAE, being successfully embolized at the second TAE after readmission with hematuria. Otherwise, no bleeding recurrence or RAPs were observed during the median 1354 follow-up days. Thus, the primary and secondary success rates of TAE were 98.8% (81 of 82 patients) and 100% (82 of 82 patients), respectively. On angiography, the average number of lesions was 1.7 ± 0.9 and the average RAP size was 12.8 ± 6.0 mm. The shapes of the lesions varied: oval-round 60, oval-round + AVF 36, irregular + AVF 14, AVF 12, irregular 10, disruption 4, and extravasation 3. No major complications were observed. The median inpatient days after TAE were two. No estimated glomerular filtration rate deterioration was observed (64.6 ± 18.6 vs. 64.2 ± 18.4 mL/min/1.73 m2, p = 0.902). Conclusion TAE is largely effective and safe for treating bleedings or RAPs, including AVFs, after partial nephrectomy, as screened by early postoperative CE-CT.

Abstract
OBJECTIVE Our specific aim was to introduce the TachoSil binding suturing technique for renal cell carcinoma (RCC) patients when closing the parenchymal defect after tumor excision during laparoscopic partial nephrectomy (LPN), which is a novel technique for reducing the risk of developing subsequent pseudoaneurysm (PA). METHODS We identified 113 pT1aN0M0 RCC patients who underwent LPN at our institution. Eighty-one (72%) patients underwent the suturing procedure without binding TachoSil, whereas 32 (28%) patients underwent renorraphy with the renal defect closed together with TachoSil. The vascular complications were evaluated by computed tomography or magnetic resonance imaging with enhanced contrast material at the first visit after LPN. We conducted Fischer's exact test to determine risk factors for transcatheter arterial embolization (TAE). RESULTS The median age was 55 (36-86) years old and the median follow-up time was 65 (12-147) months. In the overall population, there were 11 (11%) patients who underwent TAE because they developed PA. All 11 patients exhibited the imaging findings of PA, and were all from the conventional suturing group. In contrast, no patients for whom the TachoSil binding method was used had any significant findings on imaging (14% vs. 0%). Based on the analysis to determine risk factors for TAE due to PA development, the TachoSil binding suturing technique was one of the significant indicators for reducing the risk of developing PA. CONCLUSIONS Our study demonstrated that the TachoSil binding suturing technique might reduce the development of PA after LPN. Prospective randomized study and comparison to the standard 2 or 3-layer renorrhaphy is needed to prove its actual value.

Abstract
INTRODUCTION AND OBJECTIVE Partial nephrectomy (PN) represents the current surgical standard for T1 tumors. Renal arterial pseudoaneurysm is a rare but potentially life-threatening complication reported after PN. The aim of this study was to identify the factors associated with the occurrence of pseudoaneurysm after PN, specifically focusing on those requiring management with selective embolization. A literature review of the topic was performed. METHODS A retrospective review of the institutional PN database was performed from January 2011 to December 2016. Patients who underwent embolization for pseudoaneurysm represented a separated cohort to be compared with other patients (controls). Patients' and tumors' characteristics were considered. Univariable and multivariable analyses were used to test their eventual association with the occurrence of pseudoaneurysm. RESULTS A total of 1417 cases were evaluated. At a median of 21 days (interquartile range = 10-34), 20 patients (1.4%) developed postoperative pseudoaneurysm. The majority of patients (70%) presented with gross hematuria. The clinical suspicion was confirmed by contrast-enhanced computed tomography scan with angiography. Selective embolization was performed using endovascular coils. Technical success and clinical success rates were 100% and 95%, respectively. No difference was found in percentage estimated glomerular filtration rate (eGFR) preserved between patients who underwent embolization versus controls (median 82.6% versus 86.3%, P = .35). No differences in age, baseline renal function (as assessed by glomerular filtration rate [GFR]), tumor size, and R.E.N.A.L. were found between patients who reported and did not report pseudoaneurysm. In patients who developed pseudoaneurysm, longer operative time (225.6 minutes versus 193 minutes, P = .04), and cold ischemia time (48 minutes versus 29 minutes, P = .03) were reported. CONCLUSION In our series, the occurrence of pseudoaneurysm was associated with longer operative and cold ischemia times. In patients who underwent selective embolization, renal function remained comparable with that of controls.

Abstract
PURPOSE To describe the incidence of multiple renal artery pseudoaneurysms (PSA) in patients referred for renal artery embolization following partial nephrectomy and to study its relationship to RENAL nephrometry scores. MATERIALS AND METHODS The medical records of 25 patients referred for renal artery embolization after partial nephrectomy were retrospectively reviewed for the following parameters: size and number of tumors, RENAL nephrometry scores, angiographic abnormalities, technical and clinical outcomes, and estimated glomerular filtration rates (eGFRs) after embolization. RESULTS Twenty-four patients had primary renal tumors, while 1 patient had a pancreatic tumor invading the kidney. Multiple tumors were resected in 4 patients. Most patients (92 %) were symptomatic, presenting with gross hematuria, flank pain, or both. Angiography revealed PSA with (n = 5) or without (n = 20) AV fistulae. Sixteen patients (64 %) had multiple PSA involving multiple renal vessels. Higher RENAL nephrometry scores were associated with an increasing likelihood of multiple PSA. Multiple vessels were embolized in 14 patients (56 %). Clinical success was achieved after one (n = 22) or two (n = 3) embolization sessions in all patients. Post-embolization eGFR values at different time points after embolization were not significantly different from the post-operative eGFR. CONCLUSION A majority of patients requiring renal artery embolization following partial nephrectomy have multiple pseudoaneurysms, often requiring selective embolization of multiple vessels. Higher RENAL nephrometry score is associated with an increasing likelihood of multiple pseudoaneurysms. We found transarterial embolization to be a safe and effective treatment option with no long-term adverse effect on renal function in all but one patient with a solitary kidney.

Abstract
Background With the wider application of nephron-sparing surgery, there has been an increase in the occurrence of postoperative hemorrhage. However, despite such an increase, there are only a limited number of reports regarding renal artery embolization (RAE) for the management of postoperative bleeding after nephron-sparing surgery, especially after robot-assisted laparoscopic partial nephrectomy (RALPN). Purpose To evaluate the safety and clinical efficacy of transcatheter RAE for postoperative hemorrhage after open partial nephrectomy (OPN) and RALPN. Material and Methods A total of 29 patients (17 men, 12 women; age range, 31–70 years) who were referred to our hospital for postoperative hemorrhage after partial nephrectomy, between December 2003 and December 2014, were selected. We retrospectively reviewed patients’ clinical data, angiographic findings, embolization details, and clinical outcomes. Results Embolization was performed in patients who underwent OPN (25/29) and RALPN (4/29). The angiographic findings were as follows: renal artery pseudoaneurysm (n = 18), contrast extravasation (n = 8), and arteriovenous fistula (n = 3). Fiber-coated microcoil and n-butyl-2-cyanoacrylate (NBCA) was administered to the targeted bleeding renal arteries in 12 and 11 patients, respectively. In six patients, fiber-coated microcoil and NBCA were used concurrently. Technical and clinical successes were achieved in all patients (100%). Bleeding cessation was achieved in all patients, and no further relevant surgeries or interventions were required for hemorrhage control. There were no episodes of hemorrhagic recurrence during the follow-up period (median, 20 days; range, 7–108 days). Conclusion Angiography and RAE identified the origin of bleeding and could successfully preserve the residual renal function.

Abstract
OBJECTIVES The aim of this study was to investigate the clinical usefulness for prediction of outcome of laparoscopic partial nephrectomy (LPN) using the R.E.N.A.L nephrometry scoring system (RNS) and centrality index score (C-index). MATERIALS AND METHODS We retrospectively reviewed 64 patients who underwent LPN from 2010 to 2014 in our institution. The RNS and C-index scores were assigned according to the described protocols for their systems. The relationships between the patients' scores before surgery and the outcomes of LPN, warm ischemia time (WIT), operative time (ORT), estimated blood loss (EBL), and percent change in estimated glomerular filtration rate (eGFR) were analyzed retrospectively. RESULTS Mean tumor size was 3.1 cm, mean WIT was 27.6 minutes, mean ORT was 189.0 minutes, and mean EBL was 187 mL. Although the RNS had statistically significant correlations with WIT, ORT, and percent change in eGFR, these correlations were not score-dependent. For WIT, a statistically significant difference was observed between the low-risk group and the middle-risk group. For percent change in eGFR, a statistically significant difference was observed between the low-risk group and the high-risk group only. For the C-index, statistically significant correlations between complexity categories and WIT, ORT, EBL, and percent change in eGFR were observed. Regarding the raw C-index scores, linear correlations were observed between the scores and each outcome of LPN. CONCLUSIONS The RNS and C-index are useful for predicting the complexity of LPN. The C-index may be more suitable than the RNS for predicting postoperative renal function.

Abstract
Objectives. A symptomatic renal pseudoaneurysm (RPA) is a severe complication after open partial nephrectomy (OPN). The aim of our study was to assess incidence and risk factors for RPA formation. Furthermore, we present our management strategy. Patients and Methods. Clinical records of consecutive patients undergoing OPN were assessed for surgical outcome and postoperative complications. Renal masses were risk stratified for tumor complexity according to the PADUA score. Uni- and multivariate analysis for symptomatic RPAs were performed using the t-tests and logistic regression. Results. We identified 233 patients treated with OPN. Symptomatic RPAs were observed in 13 (5.6%) patients, on average 14 (4–42) days after surgery. Uni- and multivariate analysis identified tumor complexity to be an independent predictor for symptomatic RPAs (p = 0.004). There was a significant correlation between RPAs and transfusion and the duration of stay (p < 0.001 and p = 0.021). Symptomatic RPAs were diagnosed with CT scans and successfully treated with arterial embolization. Discussion. Symptomatic RPAs are not uncommon after OPN for high-risk renal masses. A high nephrometry score is a predictor for this severe complication and may enable a risk-stratified followup. RPAs can successfully be located by CT angiography, which enables targeted angiographic treatment.

Abstract
OBJECTIVE To evaluate the incidence of and risk factors for a urine leak in a large multicentre, prospective database of robot-assisted partial nephrectomy (RPN). PATIENTS AND METHODS A database of 1 791 RPN from five USA centres was reviewed for urine leak as a complication of RPN. Patient and tumour characteristics were compared between patients with and those without postoperative urine leaks. Fisher's exact test was used for qualitative variables and Wilcoxon sum-rank tests were used for quantitative variables. A review of the literature on PN and urine leak was conducted. RESULTS Urine leak was noted in 14/1 791 (0.78%) patients who underwent RPN. The mean (sd) nephrometry score of the entire cohort was 7.2 (1.9), and 8.0 (1.9) in patients who developed urine leak. The median (range) postoperative day of presentation was 13 (3-32) days. Patients with urine leak presented in delayed fashion with fever (two of the 14 patients, 14%), gastrointestinal complaints (four patients, 29%), and pain (five patients, 36%). Eight of the 14 patients (57%) required admission, while eight (57%) and nine (64%) had a drain or stent placed, respectively. Drains and stents were removed after a median (range) of 8 (4-13) days and 21 (8-83) days, respectively. Variables associated with urine leak included tumour size (P = 0.021), hilar location (P = 0.025), operative time (P = 0.006), warm ischaemia time (P = 0.005), and pelvicalyceal repair (P = 0.018). Upon literature review, the historical incidence of urine leak ranged from 1.0% to 17.4% for open PN and 1.6-16.5% for laparoscopic PN. CONCLUSION The incidence of urine leak after RPN is very low and may be predicted by some preoperative factors, affording better patient counselling of risks. The low urinary leak rate may be attributed to the enhanced visualisation and suturing technique that accompanies the robotic approach.

Abstract
OBJECTIVE To study the accuracy of CT for staging T3a (TNM 2009) renal cell carcinoma (RCC). METHODS Unenhanced and nephrographic phase CT studies of 117 patients (male:female = 82:35; age range, 21-86 years) with T1-T3a RCC were independently reviewed by 2 readers. The presence of sinus or perinephric fat, or renal vein invasion and tumour characteristics were noted. RESULTS Median (range) tumour size was 5.5 (0.9-19.0) cm; and 46 (39%), 16 (14%) and 55 (47%) tumours were pT1, pT2 and pT3a RCC, respectively. The sensitivity/specificity for sinus fat, perinephric fat and renal vein invasion were 71/79%, 83/76% and 59/93% (Reader 1) and 88/71%, 68/72% and 69/91% (Reader 2) with κ = 0.41, 0.43 and 0.61, respectively. Sinus fat invasion was seen in 47/55 (85%) cases with T3a RCC vs 16/55 (29%) and 33/55 (60%) for perinephric fat and renal vein invasion. Tumour necrosis, irregularity of tumour edge and direct tumour contact with perirenal fascia or sinus fat increased the odds of local invasion [odds ratio (OR), 2.5-3.7; p < 0.05; κ = 0.42-0.61]. Stage T3a tumours were centrally located (OR, 3.9; p = 0.0009). CONCLUSION Stage T3a RCC was identified with a sensitivity of 59-88% and specificity of 71-93% (κ = 0.41-0.61). Sinus fat invasion was the most common invasive feature. ADVANCES IN KNOWLEDGE Centrally situated renal tumours with an irregular tumour edge, inseparable from sinus structures or the perirenal fascia and CT features of tumour necrosis should alert the reader to the possibility of Stage T3a RCC (OR, 2.5-3.9).

Abstract
The skill of supra-12th rib mini-flank approach for open partial nephrectomy (MI-OPN) provides an advanced operative method for renal tumor. Compared with laparoscopic and robotic surgery, it may be a feasible selection for the complex renal tumors. We describe our techniques and results of MI-OPN in complex renal tumors with high RENAL nephrometry score (RENAL nephrometry score ≥10). Fifty-five patients diagnosed with renal tumors between January 2009 and July 2013 were included in this study. Eligibility criteria comprised of patients with complex renal tumor (RENAL score ≥10) being candidates for partial nephrectomy (PN). All patients received MI-OPN and all surgeries were performed by a single urologist. The preoperative workup comprised of medical history, physical examination, and routine laboratory tests. Serum creatinine was recorded preoperatively and 2 to 3 months after operation. Operative time, ischemia time, blood loss, operative and postoperative complications, renal function, and pathology parameters were recorded. MI-OPN was successfully performed in all cases. Mean tumor size was 4.7 cm (range: 2.5-8.1). Mean warm ischemia time was 28.1 minutes (range: 21-39), mean operative time was 105 minutes (range: 70-150) and mean estimated blood loss was 68 mL (range: 10-400). Mean postoperative hospital stay was 6.5 days (range: 5-12). Postoperative complications were found in 3 patients (5.5%). The mean pre- and postoperative serum creatinine levels were 76.2 μmol/L (range: 47-132) and 87.1 μmol/L (range: 61-189) with significant difference (P = 0.004). The mean pre- and postoperative estimated glomerular filtration rate (eGFR) were 91.5 (range: 34-133) and 82.5 (range: 22-126.5), respectively with significant difference (P = 0.024). In an average follow-up of 19.9 months (range: 8-50), no local recurrence or systemic progression occurred. In conclusion, MI-OPN can combine the benefits of both minimal invasive and traditional open partial nephrectomy (OPN) techniques with a smaller incision. It is an innovation of traditional OPN and suitable for the complex renal tumors with high RENAL nephrometry score safely and effectively.

Abstract
OBJECTIVES To investigate the incidence of asymptomatic unruptured renal artery pseudoaneurysm detected by 3-D computed tomography arteriography in the early period after minimally invasive partial nephrectomy, including laparoscopic and robotic partial nephrectomy. METHODS From February 2012 to November 2013, 101 patients underwent minimally invasive partial nephrectomy for renal masses. Computed tomography arteriography was carried out 3-4 days after surgery; radiologists diagnosed renal artery pseudoaneurysm in a blinded manner. Factors influencing the occurrence of renal artery pseudoaneurysm were analyzed with the logistic regression model. RESULTS The incidence of renal artery pseudoaneurysm was unexpectedly high at 21.7% when detected by computed tomography arteriography during the early period after minimally invasive partial nephrectomy. The renal artery pseudoaneurysm group showed a significantly larger tumor size (P = 0.02), significantly higher N component score (P = 0.01) and higher incidence of renal sinus exposure or opening of the collecting system (P < 0.01) compared with the no renal artery pseudoaneurysm group. Although these aforementioned factors were found to be significant by univariate analysis, multivariate analysis showed that renal sinus exposure was the only significant independent predictive factor for occurrence of renal artery pseudoaneurysm. Tumor-related factors, such as the N component of the nephrometry scoring system or tumor size, did not show an independent influence on the occurrence of renal artery pseudoaneurysm. CONCLUSIONS The present study shows an unexpectedly high incidence of asymptomatic unruptured renal artery pseudoaneurysm detected by computed tomography arteriography in the early period after minimally invasive partial nephrectomy. Renal sinus exposure is an independent significant factor predicting the occurrence of renal artery pseudoaneurysm. Avoidance of deep excision into the renal sinus could reduce the risk of renal artery pseudoaneurysm.

Abstract
OBJECTIVES We systematically examined the incidence and potential implications of renal artery pseudoaneurysm occurring after partial nephrectomy detected by computed tomography screening in the early postoperative period. METHODS Between January and December 2012, 117 patients underwent enhanced screening computed tomography on the fourth postoperative day after partial nephrectomy to evaluate for renal artery pseudoaneurysm. The size of the renal artery pseudoaneurysm and follow-up imaging were utilized to decide on pre-emptive angioembolization. Patient characteristics, tumor specifics and surgical data were analyzed. RESULTS A total of 17 of 117 patients (15%) were found to have renal artery pseudoaneurysm on early postoperative computed tomography. Renal artery pseudoaneurysm occurred in nine of 73 open partial nephrectomy patients (12.3%) and eight of 44 laparoscopic partial nephrectomy patients (18.2%). One early patient experienced a postoperative bleed on postoperative day 9 after diagnosis of a 3.5-mm diameter renal artery pseudoaneurysm on postoperative day 3, and this patient was successfully managed with angioembolization. There were no other postoperative bleeding episodes. Rapid growth of a renal artery pseudoaneurysm was observed in a second patient who was treated with pre-emptive angioembolization. Five patients were diagnosed with small renal artery pseudoaneurysm (2-4 mm) on postoperative day 4 and observed with follow-up imaging showing resolution of the renal artery pseudoaneurysm. Another 10 patients were diagnosed with larger renal artery pseudoaneurysm (≥4 mm) and were managed with pre-emptive angioembolization. CONCLUSIONS Early postoperative computed tomography screening is able to detect modest rates of asymptomatic renal artery pseudoaneurysm. The rate of postoperative bleed remained low with a policy of selective angioembolization. Renal artery pseudoaneurysm size and interval enlargement might indicate the risk of rupture. Further studies are required to assess the potential role of pre-emptive angioembolization.

Abstract
Laparoscopic partial nephrectomy has recently emerged as a minimally invasive treatment for small- to moderate-sized renal tumors. Renal artery pseudoaneurysms (RAPs) have been well-reported in patients with renal trauma or who have undergone percutaneous urological procedures, including biopsy, nephrostomy and percutaneous nephroureterolithotomy. However, RAP following laparoscopic partial nephrectomy for central renal tumor is a rare but serious, potentially life-threatening complication. In total, two patients underwent laparoscopic partial nephrectomy at The First Affiliated Hospital of Zhejiang University School of Medicine (Hangzhou, China) for central renal tumors that had developed gross hematuria several weeks following the surgical procedures. The formation of RAPs was confirmed by contrast-enhanced computed tomography scans. Superselective embolizations of the renal artery branches were successfully performed to treat these two patients. In the current report, the etiology, diagnosis and management of RAPs are discussed.

Abstract
Purpose The purpose of this study was to report our approach of partial nephrectomy (PN) using a supra-12th rib mini-flank incision. We compared mini-incision open partial nephrectomy (MI-OPN) with open partial nephrectomy (OPN) and laparoscopic partial nephrectomy (LPN) to verify whether MI-OPN can be an alternative to OPN and LPN. Methods This was a retrospective single-center study including 194 patients who underwent partial nephrectomy (PN) between February 2005 and December 2010. Demographic, perioperative, and complication data were compared among the MI-OPN group, OPN group and LPN group. Results No statistical differences were reported in either group for age, sex, BMI, tumour side (right or left kidney), RENAL nephrometry scores, PADUA score and preoperative eGFR. The operative time was longer in LPN group when compared with MI-OPN and OPN group (all P<0.001). The warm ischemia time of LPN group was longer than MI-OPN group (P = 0.032) and OPN group (P = 0.005). The length of stay of LPN group was shorter than OPN group (P = 0.018), but was similar to MI-OPN group (P = 0.094). The incidence of renal artery clamping was lower in OPN group when compared with MI-OPN and LPN group (all P<0.001). More estimated blood loss was found in OPN group when compared with MI-OPN group (p = 0.003) and LPN group (P = 0.014). The overall incidence of postoperative complications was similar. Conclusions The approach of MI-OPN can couple the benefits of both minimally invasive and open partial nephrectomy techniques with less estimated blood loss, shorter operative time, shorter length of stay, less postoperative complications, and a smaller incision. MI-OPN may be an effective alternative to laparoscopic or traditional open approaches, which maybe more suitable for the tumors with high RENAL nephrometry score or PADUA score.

Abstract
Purpose To evaluate the frequency and clinical characteristics of postoperative hemorrhage as a complication of partial nephrectomy. Materials and Methods The demographics, physical statistics, tumor size, R.E.N.A.L. nephrometry score, operative method, warm ischemic time, and presence of postoperative hemorrhage and its severity and method of intervention were examined in 300 partial nephrectomy patients in two medical centers (Stanford Medical Center and Kyung Hee University Medical Center) between March 2000 and March 2012. Results Of the 300 subjects, 13 (4.3%) experienced postoperative hemorrhage severe enough to require intervention more invasive than transfusion (Clavien grade III or higher). Univariate analysis of the bleeding and nonbleeding groups showed that whereas age, ischemic time, tumor size and stage, body mass index, American Society of Anesthesiologists class, and operative method did not differ significantly, the exophyticity (E) score was significantly higher for severe postoperative hemorrhage (p=0.04). However, multivariate analysis showed none of the factors to differ significantly. In most of the cases requiring intervention, selective embolization was sufficient, but in one case explorative laparotomy and nephrectomy were required. Clinical characteristics varied significantly among severe hemorrhage cases, with time of onset ranging from the first to the 30th postoperative day and symptoms presenting in a diverse manner, such as gross hematuria and pleuritic chest pain. Computed tomography and angiographic findings were consistent with either arteriovenous fistula or pseudoaneurysms. Conclusions Severe hemorrhage after partial nephrectomy is rare. Nonetheless, with the great variability in presenting symptoms and time of onset after surgery, surgeons should exercise great vigilance during the postoperative care of partial nephrectomy patients.

Abstract
OBJECTIVES To report our initial experience in retroperitoneal laparoscopic partial nephrectomy (LPN) for moderately complex renal hilar tumors and summarize the feasibility of the retroperitoneal laparoscopic approach. MATERIALS AND METHODS 14 patients with renal hilar tumors underwent retroperitoneal LPN between June 2010 and January 2012 at our institution. All of the masses were confirmed in the hilar location by computed tomography preoperatively and then evaluated with the R.E.N.A.L. nephrometry scoring system; all were defined as moderately complex lesions. A three-port retroperitoneal approach with a dorsal incision was used in all cases. Patient baseline demographics, perioperative outcomes and pathological characteristics were recorded based on a retrospective data collection and telephone interview. RESULTS All operations were performed successfully without conversion to radical nephrectomy or open surgery. Only two complications of perirenal fluid collection occurred, but the patients recovered with active surveillance. Mean operative time was 134.3 min, mean estimated blood loss 133.2 ml, mean warm ischemia time 30.6 min and mean retroperitoneal drainage 2.2 days. Mean postoperative hospital stay was 4.7 days. No recurrence or metastasis occurred in these patients at a mean follow-up of 18.6 months. CONCLUSIONS Our initial experience suggests that retroperitoneal LPN is a feasible, safe and effective procedure for moderately complex renal hilar tumors. Although it remains technically challenging, this approach can be recommended in some complex cases when in experienced hands.

Abstract
INTRODUCTION Comparison of treatments for partial nephrectomy is limited by case selection. We compared robotic (RPN), laparoscopic (LPN), and open partial nephrectomy (OPN), controlling for tumor size, patient age, sex, and nephrometry score. METHODS RPN, LPN, and OPN procedures between March 2003 and March 2010 were reviewed. All RPN and LPN were included, and 2 OPN were matched for each RPN in tumor size (±0.5cm), patient age (±10 y), sex, and nephrometry score. Perioperative outcomes were compared. RESULTS Ninety-six partial nephrectomy procedures were reviewed: 27 RPN, 15 LPN, and 54 OPN. RPN, LPN, and OPN had similar median tumor size (2.4, 2.2, and 2.3cm, respectively), nephrometry score (6.0 each), and preoperative glomerular filtration rate (71.5, 84.6, and 77.0 mL/min/1.73m(2), respectively). Blood loss was higher for OPN (250 mL) than for RPN or LPN (100 mL), P < 0.001. Operative time was shorter in OPN (147 min) than in RPN (190 min) or LPN (195 min), P < .001. Median warm ischemia time was shorter for OPN (12.0 min) than for RPN (25.0 min) or LPN (29.5 min), P Kt; .05. Cold ischemia time for OPN was 25.0 min. A 10% glomerular filtration rate decline occurred in 10 RPN, 5 LPN, and 29 OPN cases (P < .252). Median hospital stay for LPN and RPN was 2.0 d versus 3.0 d for OPN (P < .001). Urine leak occurred in 1 RPN and 3 OPN cases. Postoperative complications occurred in 4 RPN (3 were Clavien grade 2 or less), 1 LPN (grade 1), and 7 OPN (6 were grade 2 or less) cases. CONCLUSION Renal function preservation and complications are similar for each treatment modality. OPN offers faster operative and ischemia times at the expense of greater blood loss and hospital stay.

Abstract
BACKGROUND There are scant data on patient safety and the national diffusion of surgical innovations. Laparoscopic partial nephrectomy (LPN) provides an apt model for population-based analyses of patient safety and the propagation of complex surgical innovations. METHODS In the nationwide inpatient sample, we identified patients undergoing partial nephrectomy for renal tumors from 1998 to 2009 and utilized patient safety indicators (PSI) to measure preventable adverse outcomes. RESULTS Of the cases, 68,713 (87 %) were OPN and 9,842 (13 %) were LPN. The prevalence of LPN increased more than threefold from 2006 to 2009. Compared to open partial nephrectomy (OPN), LPN patients were more likely to be younger (p = 0.022), have lower Charlson comorbidity scores (p = 0.002), and undergo surgery at urban (p < 0.001) and teaching (p = 0.02) hospitals. On multivariate analysis, LPN was associated with a 28 % decreased probability of any PSI (adjusted odds ratio [ORadj] 0.72, 95 % confidence interval [CI] 0.55-0.96, p = 0.025), although this benefit did not attain significance when comparing robot-assisted LPN to OPN (ORadj 0.72, 95 % CI 0.44-1.16, p = 0.173). Overall mortality decreased from 0.9 % in 1998 to 0.1 % in 2009 (p < 0.001). There were no differences in adjusted mortality between LPN and OPN (p = 0.75). CONCLUSIONS During its initial national diffusion, LPN resulted in enhanced perioperative patient safety compared to OPN. Mortality for both LPN and OPN decreased over time. Further study is needed to elucidate and promote factors contributing to the safe diffusion of complex surgical innovations.

Abstract
A case of renal artery pseudoaneurysm (RAP) after partial nephrectomy for an 11-cm renal tumor is reviewed. Symptoms, computed tomography (CT) scan images and angiography are all displayed. A 57-year-old woman was readmitted 4 months after she underwent a retroperitoneal laparoscopic partial nephrectomy for an 11-cm right renal tumor. Contrast CT revealed a 10.3-cm mass recurrence in the same position as her former tumor. Renal arteriography confirmed active bleeding from the anterior upper pole segmental branch into a 3 × 3 × 7-cm pseudoaneurysm. Percutaneous selective coil angioembolization was successfully performed. The remaining kidney parenchyma was fully preserved.

Abstract
INTRODUCTION Bleeding after partial nephrectomy can be immediate or delayed and may have severe consequences. The incidence of this complication is low. The most frequent cause of delayed bleeding is arterial pseudoaneurysm. Superselective embolization is a feasible therapeutic option that has shown good results. OBJECTIVE To evaluate treatment and outcomes of delayed bleeding in our series of patients with partial nephrectomy. MATERIAL AND METHODS We performed a retrospective study of our database of partial nephrectomies. Patients who developed delayed bleeding (after discharge) were identified. Clinical histories were reviewed and data on presentation, diagnosis, treatment and outcomes were analyzed. RESULTS Among our series of patients undergoing partial nephrectomy, three developed delayed bleeding (1.3%). Symptom onset occurred 17 to 25 days after surgery and consisted of hematuria or lumbar pain. Diagnosis was provided through ultrasound, abdominal computed tomography and renal angiography. In all three patients, a complicated pseudoaneurysm was diagnosed and all patients underwent renal artery catheterization with selective renal artery embolization. In all patients, immediate control of bleeding was achieved. Outcome after a follow-up of 61 to 92 months was favorable. CONCLUSIONS Selective vascular embolization is the treatment of choice of renal pseudoaneurysm after partial nephrectomy in hemodynamically stable patients.

Iatrogenic vascular lesions after minimally invasive partial nephrectomy: a multi-institutional study of clinical and renal functional outcomes. Urology 2011; 78:820-6. [PMID: 21813164 DOI: 10.1016/j.urology.2011.04.063] [Citation(s) in RCA: 58] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2011] [Revised: 04/04/2011] [Accepted: 04/04/2011] [Indexed: 11/24/2022]
Abstract
OBJECTIVES To report the first large multi-institutional experience, including clinical and renal functional outcomes after treatment of iatrogenic vascular lesions (eg, renal artery pseudoaneurysm, arteriovenous fistula). These lesions are uncommon after minimally invasive partial nephrectomy (MIPN) but can be associated with significant morbidity. METHODS A retrospective review of MIPN was performed at 4 centers. Patients developing pseudoaneurysm or arteriovenous fistula in the postoperative period were identified. The demographic, disease, and perioperative details and data regarding the presentation and treatment of vascular lesions were collected. RESULTS Of the 998 patients undergoing MIPN, 20 (2.0%) presented with iatrogenic vascular lesions (17 with pseudoaneurysm and 3 with arteriovenous fistula). The mean age was 55.9 years, the tumor size was 2.6 cm, and the body mass index was 30.8 kg/m(2). Twelve patients (60%) had >50% endophytic tumors, 7 patients (35%) had undergone collecting system repair, and the mean warm ischemia time was 26 minutes. All patients presented with gross hematuria at a mean of 14.5 days postoperatively. The diagnosis was made using urgent computed tomography scan in all cases. Selective embolization was performed in 16 patients; 2 required no intervention and had spontaneous resolution, and 2 had negative angiography findings. Four patients required transfusion during rehospitalization. Although 4 patients had categorical worsening of the glomerular filtration rate after MIPN, all patients had stable function acutely after angioembolization, and 3 patients had categorical glomerular filtration rate improvement through a mean follow-up of 20 months. No patients had recurrent hemorrhagic events. CONCLUSIONS Iatrogenic vascular lesions occur in ∼2% of MIPN cases. Although a subset of patients will have resolution with observation only, most require angioembolization, with excellent clinical and renal function outcomes.

Abstract
CONTEXT The increasing incidence of localised renal cell carcinoma (RCC) over the last 3 decades and controversy over mortality rates have prompted reassessment of current treatment. OBJECTIVE To critically review the recent data on the management of localised RCC to arrive at a general consensus. EVIDENCE ACQUISITION A Medline search was performed from January 1, 2004, to May 3, 2011, using renal cell carcinoma, nephrectomy (Medical Subject Heading [MeSH] major topic), surgical procedures, minimally invasive (MeSH major topic), nephron-sparing surgery, cryoablation, radiofrequency ablation, surveillance, and watchful waiting. EVIDENCE SYNTHESIS Initial active surveillance (AS) should be a first treatment option for small renal masses (SRMs) <4 cm in unfit patients or those with limited life expectancy. SRMs that show fast growth or reach 4 cm in diameter while on AS should be considered for treatment. Partial nephrectomy (PN) is the established treatment for T1a tumours (<4 cm) and an emerging standard treatment for T1b tumours (4-7 cm) provided that the operation is technically feasible and the tumour can be completely removed. Radical nephrectomy (RN) should be limited to those cases where the tumour is not amenable to nephron-sparing surgery (NSS). Laparoscopic radical nephrectomy (LRN) has benefits over open RN in terms of morbidity and should be the standard of care for T1 and T2 tumours, provided that it is performed in an advanced laparoscopic centre and NSS is not applicable. Open PN, not LRN, should be performed if minimally invasive expertise is not available. At this time, there is insufficient long-term data available to adequately compare ablative techniques with surgical options. Therefore ablative therapies should be reserved for carefully selected high surgical risk patients with SRMs <4 cm. CONCLUSIONS The choice of treatment for the patient with localised RCC needs to be individualised. Preservation of renal function without compromising the oncologic outcome should be the most important goal in the decision-making process.

Abstract
PURPOSE We describe the presentation, endovascular management and functional outcomes of 15 patients with renal arterial pseudoaneurysm following open and laparoscopic partial nephrectomy. MATERIALS AND METHODS An institutional review board approved, Health Insurance Portability and Accountability Act compliant retrospective review of a prospectively maintained database revealed that 7 of 1,160 patients who underwent open partial nephrectomy and 8 of 301 treated with laparoscopic partial nephrectomy were diagnosed with a pseudoaneurysm of a renal artery branch between 2003 and 2010. Some cases were associated with arteriovenous fistula. RESULTS Diagnosis of pseudoaneurysm was made a median of 14 days after surgery. Gross hematuria was the most frequent symptom. Median estimated glomerular filtration rate measurements at the preoperative evaluation, postoperatively, on the day the vascular lesion was diagnosed, after embolization and at the last followup were 62, 55, 55, 56 and 58 ml/minute/1.73 m(2), respectively. Median followup was 7.8 months. All patients underwent angiography and superselective coil embolization of 1 or more pseudoaneurysms with or without arteriovenous fistula. Eleven patients had immediate cessation of symptoms while 4 had persistent gross hematuria after the procedure. Of these 4 patients 2 were treated with bedside care, 1 required repeat embolization with thrombin, which was successful, and the remaining patient had coagulopathy and underwent radical nephrectomy for persistent bleeding. CONCLUSIONS Pseudoaneurysms and arteriovenous fistulas of the renal artery are rare complications of partial nephrectomy. Presentation is often delayed. Superselective coil embolization is a safe, minimally invasive treatment option that usually solves the clinical problem and preserves renal function.

Abstract
OBJECTIVE • To assess the use of the RENAL Nephrometry Score (RNS), which has been proposed as an anatomical classification system for renal masses, aiming to predict surgical outcomes for patients undergoing laparoscopic partial nephrectomy (LPN). MATERIALS AND METHODS • In the present study, 159 consecutive patients who underwent LPN were reviewed and RNS was calculated for 141 patients with solitary renal masses who had complete radiographic data. • Renal tumours were categorized by RNS as low (nephrometry sum 4-6), intermediate (sum 7-9) and high (sum 10-12). RESULTS • Of the 141 patients, there were 43 (30%) low, 91 (65%) intermediate and seven (5%) high score lesions. There was no statistically significant difference in the demographics of the three groups. • There was a significant difference in warm ischaemia time (16 vs 23 vs 31 min; P < 0.001), estimated blood loss (163 vs 312 vs 317 mL; P= 0.034) and length of hospital stay (1.2 vs 1.9 vs 2.3 days; P < 0.001) between the low, intermediate and high score groups, respectively. There was no difference in overall operative time (P= 0.862), transfusion rate (P= 0.665), complication rate (P= 0.419), preoperative creatinine clearance (P= 0.888) or postoperative creatinine clearance (P= 0.473) between the groups. • Sixty-one lesions (43%) were anterior and 80 (57%) were posterior. No difference was found among any intra-operative, pathological or postoperative outcomes when comparing anterior vs posterior lesions. CONCLUSIONS • In patients undergoing LPN, a higher RNS was significantly associated with an increased estimated blood loss, warm ischaemia time and length of hospital stay. • The RNS may stratify tumours based on the technical difficulty of performing LPN.

Abstract
OBJECTIVES Surgical outcomes for a simplified LPN technique using a single-layer closure were reviewed for central and peripheral renal tumors. METHODS A total of 159 consecutive patients who underwent LPN were identified using a single-institution database. Renal tumors abutting the collecting system or renal sinus were considered central. After tumor excision, the tumor bed was repaired using a single layer closure by passing partially straightened CPX needles beneath the entire cut surface. Pathologic and postoperative outcomes were compared between the central tumor group (CTG) and the peripheral tumor group (PTG). RESULTS There were 83 and 76 patients in the CTG and PTG, respectively. When compared with the PTG, the CTG had a larger mean tumor size (3.4 vs 2.3 cm, P <.0001) and greater depth of tumor invasion (2.3 vs 1.1 cm, P <.0001). In the CTG, 66 tumors were malignant, and 2 patients had a positive margin. In the PTG, 50 tumors were malignant, and 1 patient had a positive margin. There was no statistically significant difference between the groups in operative times, estimated blood loss, transfusion rates, complications, positive margins, and length of hospital stays. The CTG had a longer warm ischemia time (24 vs 18 minutes, P = .0002), but this did not result in a significant difference in postoperative creatinine clearance (86 vs 87, P = .842). CONCLUSIONS During LPN, a single-layer closure without bolsters is safe and effective, and early surgical outcomes are similar for central and peripheral tumors.

Abstract
To analyse the current evidence of efficacy and safety of nephron-sparing surgery (NSS) that encompasses open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN) and robotic partial nephrectomy in the management of localized renal cell carcinoma (RCC). Oncological data, complications and postoperative renal function were reviewed for the most important series of partial nephrectomy. Partial nephrectomy (PN) provides similar oncological control as radical nephrectomy (RN) and is superior to RN with respect to preserving renal function and preventing chronic kidney disease. OPN remains the first treatment option for T1 renal tumors in centers without advanced laparoscopic expertise. Indications for LPN have expanded as such that LPN is suited for most renal tumors provided that the procedure is carried out in selected patients by an experienced laparoscopic surgeon. Warm ischemia time should be kept within 20 min, which is currently recommended regardless of surgical approach. In experienced hands, LPN yields intermediate oncological efficacy and renal function outcome comparable to open surgery in the treatment of pT1 renal tumors. Positive surgical margin rates are comparable after LPN and OPN. In contemporary series, the morbidity of LPN is decreasing to become similar to that of OPN. Preliminary results with robotic PN are comparable to results obtained with LPN. Additional studies are required to validate these results and compare with other current methods, such as thermal ablation. NSS is effective and safe for the management of localized RCC and is the gold standard to which new ablative techniques need to be compared.

Abstract
PURPOSE OF REVIEW Laparoscopic partial nephrectomy (LPN) technique has continually evolved over the last decade, resulting in better outcomes and increased popularity within the urological community. In this article, we provide an overview of the contemporary literature on LPN. RECENT FINDINGS The technique of LPN has evolved over the last 5 years with a nearly 50% reduction of warm ischemia time in experienced hands. Complication rates have also declined such that morbidity and oncological outcomes are comparable to open partial nephrectomy, the gold standard. LPN is now an established procedure for the treatment of T1a renal tumors. It can also be safely performed for favorably located T1b tumors and more complex tumors, including hilar tumors, central tumors or tumors in solitary kidneys with good oncological and functional outcomes. SUMMARY For renal tumors less than 4-7 cm (T1 lesions), partial nephrectomy is the treatment of choice. Contemporary LPN is a sophisticated procedure, and in expert hands, offers perioperative, functional and oncologic outcomes comparable to open partial nephrectomy, even for complex tumors.

Abstract
PURPOSE We retrospectively reviewed the charts of patients with renal artery pseudoaneurysms (RAPs) to document their clinical presentation, surgical background, and outcome. MATERIALS AND METHODS In all, 7 of the 1965 patients who underwent percutaneous stone surgery and 3 of the 25 patients who underwent laparoscopic nephron-sparing surgery had a diagnosis of RAP and were treated accordingly. The most common symptom was hematuria, which was classified as early or delayed according to the time of presentation, as mild, moderate, or severe according to the hemodynamics of the patient. In addition, angiographic images were reviewed, and the correlation between the clinical presentation of RAP and its location was investigated. RESULTS In the percutaneous stone surgery group, four patients experienced early mild to moderate hematuria and three experienced late moderate hematuria. All of the RAPs were located on the interlobar and arcuate arteries. In the laparoscopic nephron-sparing surgery group, one patient was asymptomatic, with diagnosis of renal-cell cancer recurrence at the 3-month follow-up, and had radical nephrectomy. Two patients presented with delayed moderate hematuria with lesions that were located on the interlobar, arcuate, and segmentary arteries. Two sessions of embolization were sufficient to stop bleeding in one patient with a segmentary artery aneurysm that had unfortunately lost kidney function during follow-up. CONCLUSION There is no predictive factor for patients undergoing percutaneous nephrolithotomy procedure yet, but laparoscopic partial nephrectomy for tumors localized in the central portion of kidney may end up with RAP especially if no adjuvant sealing agents are used. The outcome of RAPs depends primarily on early recognition and a high index of suspicion, which facilitates correct diagnosis and appropriate management. Selective angiography and embolization together is the gold standard, both for diagnosis and treatment.
