RESUMO

BACKGROUND: Robotic-pyeloplasty (RP) for uretero-pelvic-junction-obstruction (UPJO) has been performed in our institution since 2013. OBJECTIVES: To summarize the outcomes of RP in adults over 18 years of age. METHODS: Adult RP cases have been prospectively documented. Analysis included demographic data such as age, sex, American Association of Anesthesiology-ASA Score, surgical-side, pre-operative imaging. Operative time (OT), estimated blood loss (EBL), length of stay (LOS) and short-term complications were also recorded. In all cases a JJ-stent has been left in place and subsequently taken out. Complications were classified in accordance with the Clavien-Dindo classification criteria. Patients were seen periodically with repeat imaging. The renal scan was performed at least once during the post-operative follow-up. Results are given as median (inter-quartile range) or numeric values (%). RESULTS: A total of 32 patients aged 33.5 years (21-45.2) had RP between the years 2013-2020, among which 53% were females and 59% right sided. An ASA score of 1-2 has been observed in 87.5% of all cases. Skin-to-skin OT was 163 min (136-185), and EBL was 5 ml (0-30). Short-term post-operative complications were hematuria (3.1%), urinary leak/urinoma (12.5%), body temperature>38.30C (12.5%). In 2 cases (6.2%) the JJ-stent had been re-positioned in the operating-theater (Clavien-Dindo 3b). LOS was 3 days (2-4) and JJ-stent had been taken out 39 days (31.7-45.2) post-operatively. Median length of follow-up was 19.5 months (9.5-26.7). In 92.3% of cases an improvement in hydronephrosis has been observed in post-operative imaging. The renal scan did not demonstrate renal function deterioration. CONCLUSIONS: Adult robotic pyeloplasty for UPJO is safe and effective. Low complication rates and over 90% success rates have been observed. These findings are in line with those found in previous studies.

RESUMO

BACKGROUND: Urinary Incontinence (UI) following Robot-Assisted Laparoscopic-Radical Prostatectomy (RALP) adversely affects patients' quality of life. OBJECTIVES: To find parameters that predict full urinary continence (FUC) following RALP. METHODS: Out of an established prospective RALP database, we retrieved and analyzed parameters that potentially predict FUC: age, Body Mass Index, American Anesthesiology Association (ASA) score, previous abdominal surgeries, pre-operative IPSS (International Prostate-Symptom Score), operative time (OT), estimated blood loss (EBL), peritoneum closure and prostate weight. FUC has been defined as 0 pads/day. Univariate analysis has been executed for comparison between patient groups, whereas multivariate analysis has been implemented for the detection of predicting factors for FUC. Data are presented as median (interquartile range) or numeric value (%). RESULTS: A total of 431 RALP cases were recorded between the years 2010-2019. Final analysis included 364 patients with full medical records; 81% gained FUC within 15 weeks (8-28); 96% gained FUC or used 1 pad/day within 17.5 weeks (8-36). Among those who gained FUC, smaller prostates (p=0.028) and low EBL (p=0.025) have been observed. On multivariate analysis EBL has been associated with UI (OR=0.9). CONCLUSIONS: Most patients gained FUC following RALP. EBL was found as risk factor for UI.

RESUMO

BACKGROUND: Partial nephrectomy is the gold standard treatment for renal tumors less than 7 cm. OBJECTIVES: To describe surgical techniques and trends of treating renal tumors less than 7 cm at our department and present the clinical outcomes of our experience with Robot-Assisted Partial Nephrectomy (RAPN). METHODS: Out of an established prospective RAPN database, we retrieved demographic, clinical, surgical and pathological parameters. Operation length was defined as the time between the first surgical incision and the last suture (skin to skin). Warm ischemia time (WIT) was defined as the time between the renal artery clamping and clamp releasing. Data is presented as mean (range, standard deviation) or numeric value (%). RESULTS: Overall, 250 RAPN cases were recorded between the years 2013-2020. Mean tumor size was 32 mm. Mean operation length was 153 minutes. Mean warm ischemia time was 17.5 minutes. Intra-operative complication rates, including converting the surgery to an open approach or to radical nephrectomy, was low. Mean estimated blood loss was 359 cc. An increase in the utilization of the robotic approach has been recorded throughout the years, with a concurrent decrease in the open and laparoscopic approaches. CONCLUSIONS: RAPN is associated with lower complication rates and superior perioperative outcomes, therefore considered a good alternative to the open and laparoscopic approaches. Thus, RAPN is the gold standard treatment for renal tumors less than 7 cm at our institute.

RESUMO

INTRODUCTION: Focal treatment for prostate cancer has been proposed as an innovative strategy that aims to achieve oncological benefit while reducing treatment-related morbidity. This treatment is suitable for patients with low and intermediate risk, organ-confined disease. Focal therapy can be categorized as follows: unifocal index lesion ablation, multifocal ablation, hemi-gland ablation or subtotal gland ablation. Different types of energies are applied in focal therapy including high intensity focal ultrasound (HIFU), cryotherapy, focal laser ablation (FLA), irreversible electroporation (IRE) and Photodynamic therapy (PDT). In this review we will briefly present a summary of leading techniques and the available data regarding their oncological outcomes and adverse events. Whole-gland therapies were excluded from this review.

RESUMO

INTRODUCTION: Upper tract urothelial carcinoma is a relatively rare malignancy, but with an increasing prevalence. The main risk factor for the disease is smoking. The most common presentation is hematuria or flank pain. Workup is made by imaging of the upper tract - CTU/MRU (Computed Tomography-Urography/Magnetic resonance (MR) urography) and diagnostic uretero-nephroscopy with biopsy. In the past several years there is major advancement in our understanding of the disease and how to treat it, mainly in nephron-sparing treatments. A risk-stratification is usually conducted according to parameters such as tumor size, distribution, and pathologic diagnosis. The low-risk group is usually offered nephron-sparing treatments such as segmental ureterectomy, endoscopic treatments, and lately - local chemotherapy. The high-risk group is usually offered radical resection of the kidney and ureter, with the possible addition of new-adjuvant and adjuvant treatments. In this article we will review the epidemiology, risk factors, diagnosis, and treatment of this malignancy, with a distinction between the risk groups.

RESUMO

BACKGROUND: Little is known about oncologic outcomes following robot-assisted-radical-prostatectomy (RALP) for clinical T3 (cT3) prostate cancer. OBJECTIVES: To investigate oncologic outcomes of patients with cT3 prostate cancer treated by RALP. METHODS: Medical records of patients who underwent RALP from 2010 to 2018 were retrieved. cT3 cases were reviewed. Demographic and pre/postoperative pathology data were analyzed. Patients were followed in 3-6 month intervals with repeat PSA analyses. Adjuvant/salvage treatments were monitored. Biochemical recurrence (BCR) meant PSA levels of ≥ 0.2 ng/ml. RESULTS: Seventy-nine patients met inclusion criteria. Median age at surgery was 64 years. Preoperative PSA level was 7.14 ng/dl, median prostate weight was 54 grams, and 23 cases (29.1%) were down-staged to pathological stage T2. Positive surgical margin rate was 42%. Five patients were lost to follow-up. Median follow-up time for the remaining 74 patients was 24 months. Postoperative relapse in PSA levels occurred in 31 patients (42%), and BCR in 28 (38%). Median time to BCR was 9 months. The overall 5-year BCR-free survival rate was 61%. Predicting factors for BCR were age (hazard-ratio [HR] 0.85, 95% confidence interval [95%CI] 0.74-0.97, P = 0.017) and prostate weight (HR 1.04, 95%CI 1.01-1.08, P = 0.021). Twenty-six patients (35%) received adjuvant/salvage treatments. Three patients died from metastatic prostate cancer 31, 52, and 78 months post-surgery. Another patient died 6 months post-surgery of unknown reasons. The 5-year cancer-specific survival rate was 92. CONCLUSIONS: RALP is an oncologic effective procedure for cT3 prostate cancer. Adjuvant/salvage treatment is needed to achieve optimal disease-control.

RESUMO

INTRODUCTION: We aimed to compare systematic biopsies (SBs) of in-bore magnetic resonance-guided prostate biopsy (MRGpB) with those performed under transrectal ultrasound (TRUS) guidance in the clinical setting. METHODS: Data on all 161 consecutive patients undergoing prostate biopsy at our institution between November 2017 and July 2019 were retrospectively collected. The patients were referred to biopsy due to elevated prostate-specific antigen (PSA) and/or abnormal digital rectal examination (DRE) and/or at least one Prostate Imaging Reporting and Data System (PI-RADS) lesion score of ≥3 on multiparametric magnetic resonance imaging (mpMRI). We included patients with PSA levels ≤20 ng/ml and those with 8-12 core biopsies. Histology results of SBs performed by in-bore MRGpB were compared to TRUS SBs. Chi-squared, Fischer's exact, and multivariate Pearson regression tests were used for statistical analysis (SPSS, IBM Corporation). RESULTS: In total, 128 patients were eligible for analysis. Their median age was 68 years (interquartile range [IQR] 61.5-72), mean prostate size 55±29 cc, and mean PSA and PSA density levels 7.6±3.5 ng/ml and 0.18±0.13 ng/ml/cc, respectively. Thirty-five patients (27.3%) had suspicious DRE findings. Both biopsy groups were similar for these parameters. Thirty-eight (62.3%) MRGpB patients had a previous biopsy vs. five (7.1%) TRUS-SB patients (p<0.0001). The number of patients diagnosed with clinically significant and non-significant disease was similar for both groups. High-risk disease was more prevalent in the TRUS-SB group (22.4% vs. 4.9%, p<0.01). CONCLUSIONS: Our data suggest that in-bore MRGpB is no better than TRUS for guiding SBs for the detection of clinically significant prostate cancer.

RESUMO

PURPOSE: We reviewed the oncologic and surgical outcomes of endoscopic treatments for low grade upper tract urothelial carcinoma, and assessed the prognostic significance of tumor size, location and multifocality. MATERIALS AND METHODS: We retrospectively reviewed all patients who underwent endoscopic treatment for low grade upper tract urothelial carcinoma at our institution between 2014 and 2019. Tumors were treated with a dual laser generator, which alternately produces holmium and neodymium lasers. A stringent ureteroscopic followup protocol was conducted. We looked for an association between outcome and tumor size, location or multifocality, and for predictive factors for time to local recurrence and progression. RESULTS: The cohort included 59 patients (62 renal units), 27% of tumors were multifocal and 40% were >2 cm. The median followup time was 22 months (IQR 11-41), and the median number of ureteroscopies was 5.5 (4-9). Local recurrence was observed in 46 renal units (74.1%) at a median of 6.5 months after initial surgery. Four patients (6.4%) developed disease progression and were referred for radical surgery: 2 had pathological progression and 2 had a rapid and high volume local recurrence, and 1 later developed metastatic disease. The progression-free rate was 93.2%. Tumor location in kidney (p=0.03, HR 1.95) and multifocality (p=0.005, HR 3.25) significantly predicted time to local recurrence. No factor predicted time to progression. CONCLUSIONS: Ureteroscopic treatment of large, multifocal, low grade upper tract urothelial carcinoma is feasible, does not involve significant complications and has good short-term oncologic outcomes, with a 93.2% progression-free survival rate. Tumors located in the kidney and multifocality yielded shorter time to local recurrence but not progression.

RESUMO

OBJECTIVE: Ad-hoc guidelines for managing the COVID-19 pandemic are published worldwide. We investigated international applications of such policies in the urologic-oncology community. METHODS: A 20-item survey was e-mailed via SurveyMonkey to 100 international senior urologic-oncology surgeons. Leaders' policies regarding clinical/surgical management and medical education were surveyed probing demographics, affiliations, urologic-oncologic areas of interest, and current transportation restrictions. Data on COVID-19 burden were retrieved from the ECDC. Statistical analyses employed non-parametric tests (SPSS v.25.0, IBM). RESULTS: Of 100 leaders from 17 countries, 63 responded to our survey, with 58 (92%) reporting university and/or cancer-center affiliations. Policies on new-patient visits remained mostly unchanged, while follow-up visits for low-risk diseases were mostly postponed, for example, 83.3% for small renal mass (SRM). Radical prostatectomy was delayed in 76.2% of cases, while maintaining scheduled timing for radical cystectomy (71.7%). Delays were longer in Europe than in the Americas for kidney cancer (SRM follow-up, P = 0.014), prostate cancer (new visits, P = 0.003), and intravesical therapy for intermediate-risk bladder cancer (P = 0.043). In Europe, COVID-19 burden correlated with policy adaptation, for example, nephrectomy delays for T2 disease (r = 0.5, P =0.005). Regarding education policies, trainees' medical education was mainly unchanged, whereas senior urologists' planned attendance at professional meetings dropped from 6 (IQR 1-11) to 2 (IQR 0-5) (P < 0.0001). CONCLUSION: Under COVID-19, senior urologic-oncology surgeons worldwide apply risk-stratified approaches to timing of clinical and surgical schedules. Policies regarding trainee education were not significantly affected. We suggest establishment of an international consortium to create a directive for coping with such future challenges to global healthcare.

RESUMO

Ureteroscopic methods have been rapidly evolving in the last several decades. With advances in flexible devices, optics and laser technologies, the endourologic surgeon has now the tools to treat high-volume tumors, in difficult locations, with good oncologic outcome. This makes radical nephroureterectomy unnecessary in some cases. Endoscopy in the setting of UTUC will surely continue to evolve and become applicable to a wider selection of patients. In this review we describe the surgical technique and provide tips and tricks which we use in our practice of endoscopic retrograde treatment of upper-tract urothelial carcinoma.

RESUMO

PURPOSE: Prostate multiparametric magnetic resonance imaging (mpMRI) improves diagnosis of clinically significant cancer and reduces over-detection of nonsignificant cancer. Disagreement in the interpretation of mpMRI readings is well-known, with a reported discrepancy rate of 10% to 42%. We report the clinical repercussions of this variability on prostate biopsy candidates. MATERIALS AND METHODS: Medical records of patients referred from 11 medical centers for MR-guided prostate biopsy (MRGpB) between October, 2017 and January, 2019 were retrospectively analyzed. Patients with at least one prostate imaging reporting and data system (PI-RADS) 3 or greater prostate lesion were selected, and the mpMRI studies (all read by others) were reviewed by our prostate mpMRI reader. Outcomes included changes in PI-RADS score and the subsequent effect on total needle samples and indication for biopsy. RESULTS: Eighty-two patients with 128 lesions were suitable for analysis (mean age 66.5 ± 7.1 years, mean PSA 6.8 ± 8.5 ng/ml). Nine (11%) patients had suspicious rectal exams (T2a). Following our prostate mpMRI reader's imaging revisions, the PI-RADS score was downgraded in 66 (52%) lesions, upgraded in 15 (12%), and unchanged in 47 (37%), leaving a total of 84 suspected lesions (kappa = 0.17). Biopsy was deferred in 22 (27%) patients, and an estimated 136.4 (34.4%) samples were avoided (P = 0.0001 for both). There was a trend toward prostate size to correlate with imaging revision and abortion of biopsy (P = 0.06) while enrollment in active surveillance correlated with proof from such outcome (P = 0.007). CONCLUSION: These data suggest that high interobserver disagreement in prostate mpMRIs from diverse institutes significantly affects prostate biopsy practice. The clinical consequences of this discord are significant.

RESUMO

BACKGROUND: Pancreatic injuries during nephrectomy are rare, despite the relatively close anatomic relation between the kidneys and the pancreas. The data regarding the incidence and outcome of pancreatic injuries are scarce. OBJECTIVES: To assess the frequency and the clinical significance of pancreatic injuries during nephrectomy. METHODS: A retrospective analysis was conducted of all patients who underwent nephrectomy over a period of 30 years (1987-2016) in a large tertiary medical center. Demographic, clinical, and surgical data were collected and analyzed. RESULTS: A total of 1674 patients underwent nephrectomy during the study period. Of those, 553 (33%) and 294 patients (17.5%) underwent left nephrectomy and radical left nephrectomy, respectively. Among those, four patients (0.2% of the total group, 0.7% of the left nephrectomy group, and 1.36% of the radical left nephrectomy) experienced iatrogenic injuries to the pancreas. None of the injuries were recognized intraoperatively. All patients were treated with drains in an attempt to control the pancreatic leak and one patient required additional surgical interventions. Average length of stay was 65 days (range 15-190 days). Mean follow-up was 23.3 months (range 7.7-115 months). CONCLUSIONS: Pancreatic injuries during nephrectomy are rare and carry a significant risk for postoperative morbidity.

RESUMO

INTRODUCTION: Until recently, radical nephroureterectomy was considered the gold standard treatment for upper tract urothelial carcinoma (UTUC). Post-operative complications, long-term adverse effects of nephrectomy as well as the risk of contralateral recurrence have led to the development of nephron-sparing techniques. OBJECTIVES: To evaluate the safety, complication rate, and oncologic outcomes of ureteroscopic nephron-sparing treatment for low-grade UTUC utilizing a hybrid laser system that incorporates two types of lasers: Nd:YAG and Ho:YAG. METHODS: We reviewed the files of patients who underwent ureteroscopic treatment for UTUC with the hybrid laser system between the years 2014-2018. Only cases of low-grade UTUC and follow-up time of at least 6 months were included in the present study. The following were analyzed: demographic data, tumor histologic characteristics, peri-operative complications, histologic upgrade, oncologic outcomes (i.e: local recurrence, local spread, metastatic progression). RESULTS: A total of 38 patients, who underwent 74 ureteroscopies, met inclusion criteria. Mean tumor size was 16.2 mm. No intra-operative complications were recorded. Two post-operative complications were recorded in one patient - hematuria and retroperitoneal bleeding - both had been treated conservatively. Mean follow-up time was 21.8 months. Local recurrence rate was 73%. Histologic upgrade has been observed in two patients. Four patients (10.5%) were referred to radical nephroureterectomy. There were no cases of local spread, distant metastases or death during the follow-up period. DISCUSSION: Endoscopic dual-laser treatment for low-grade UTUC is safe, surgically feasible and associated with good short-term oncologic outcome. Patient selection and strict follow-up are mandatory.

RESUMO

OBJECTIVE: To assess long-term outcome after selective arterial embolization (SAE) as first-line treatment for large or symptomatic AML. DESIGN, SETTING, AND PARTICIPANTS: Data from a prospectively maintained database on 71 patients who underwent SAE for large or symptomatic AML were reviewed. Patients with sporadic and tuberous-sclerosis-complex (TSC) were included. OUTCOME MEASUREMENTS: The main endpoints were re-embolization rates, occurrence of clinical events related to AML, size of AML, and renal function. RESULTS: Thirteen (19.1%) patients reported at least 1 major clinical event. Major complications affected 2 patients (2.9%), both ending in complete loss of renal unit function. Four renal units (5.9%) were eventually treated surgically. The re-embolization rate was 41.1%, with an average time from the initial to a repeat SAE of 2.18 years (range 0.31-10.65 years). The size of the tumor prior to SAE and after 5 and 10 years of follow-up were 8.9 cm (7-12), 6.5 cm (4-7.5), 7 cm (4-7.8), respectively [median (IQR)]. These results are translated to a size reduction of 27% in 10 years follow-up. Patients with TSC had larger tumors on long-term follow-up (77.8 vs 41.3 mm, P = .045). The long-term follow-up estimated average glomerular filtration rate was 81.97 (range 26-196). No patient needed renal replacement therapy, and disease-specific survival was 100%. CONCLUSIONS: SAE is a safe treatment option for patients with symptomatic or large AML. It represents a minimally invasive intervention with good long-term outcome. SAE may be offered as first-line treatment in most cases, though, it is associated with high retreatment rates.

RESUMO

BACKGROUND: Partial nephrectomy (PN) for clinical stage T3 tumors is controversial. Radical nephrectomy (RN) has been associated with a greater rate of chronic kidney disease, an increased risk of cardiovascular disease, and increased mortality compared with PN. We present our long-term 2-center experience with PN for stage pT3a tumors and compare the oncologic outcomes with those of similar patients treated with RN. MATERIALS AND METHODS: We reviewed the data from all patients who had undergone nephrectomy for renal cell carcinoma from 1987 to 2015 in 2 medical centers. The study included 134 patients with pathologic stage T3a tumors, of whom 48 and 86 underwent PN and RN, respectively. We compared the 2 groups (PN and RN) using univariate and multivariate analyses. RESULTS: The tumors of all patients with pathologic stage T3a who had undergone PN had been pathologically upstaged from clinical stage T1 or T2. Univariate and multivariate analyses revealed tumor size was significantly different statistically between the study groups (median, 7.0 cm in RN group vs. 4.0 cm in PN group; P < .001). Surgery type was not a predictor of local recurrence (P = .978), metastatic progression (P = .972), death from renal cancer (P = .626), or death from all causes (P = .974) at the 5-year follow-up point. CONCLUSION: The results of the present study have shown similar oncologic outcomes between 48 patients with stage pT3a renal cancer who underwent PN and 86 patients who underwent RN. Although PN was not performed on clinical T3a tumors, our findings suggest that PN can also be considered for these tumors and, thus, avoid the long-term complications of RN. However, strict follow-up protocols are mandatory.

RESUMO

BACKGROUND: Positive surgical margins (PSM) are recognized as an adverse prognostic sign and are often associated with higher rates of local and systemic disease recurrence. The data regarding the oncological outcome for PSM following radical nephrectomy (RN) is limited. We examined the predictive factors for PSM and its influence on survival and site of recurrence in patients treated with RN for renal cell carcinoma (RCC). METHODS: Clinical, pathologic and follow-up data on 714 patients undergoing RN for kidney cancer were analyzed. Secondary analysis included 44 patients with metastatic RCC upon diagnosis who underwent cytoreductive nephrectomy (CRN). Univariate and multivariable logistic regression models were fit to determine clinicopathologic features associated with PSM. A Cox proportional-hazards regression model was used to test the independent effects of clinical and pathologic variables on survival. RESULTS: PSM was documented in 17 cases (2.4%). PSM were associated with tumour size, advanced pathologic stage (pT3 vs. ≤ pT2) and presence of necrosis. On multivariate analysis, cancer-specific survival (CSS) was associated with tumour stage, size, presence of necrosis and PSM. PSM was also associated with local recurrence but not distant metastasis or overall survival (OS). CSS and OS were comparable between the PSM and metastatic RCC groups, but significantly lower than the negative margin group. CONCLUSIONS: The prevalence of PSM following RN is rare. Pathological data, including advanced stage (> pT2), tumour necrosis and tumour size, are associated with the presence of PSM. PSM is associated with tumour recurrence and CSS. Patients with PSM are a potential group for adjuvant therapy or for more careful and thorough follow-up following surgery.

RESUMO

INTRODUCTION: Ureteral strictures can result in obstructive nephropathy and renal function deterioration. Surgical management of ureteral defects, especially in the proximal- and mid-ureter, is particularly challenging. Our purpose was to analyze the long-term outcomes of urothelial-based reconstructive surgery for upper- and mid-ureteral defects. METHODS: We conducted a retrospective analysis of a single tertiary centre's database, including 149 patients treated for ureteral defects between 2001 and 2011. Thirty-one patients (21%) underwent complex urothelial-based surgical repairs for upper- and mid-ureter defects. Patients' median age was 61 years. The mean length of the ureteral strictures was 2.5 cm, located in upper-, mid-ureter, or in between in 19 (61%), 10 (32%), and two (6%) patients, respectively. All patients were treated with a primary urothelial-based repair. Median followup time was 26 months. The primary outcome of the study was the long-term preservation of renal function and lack of clinical obstruction. The secondary endpoint of the study was the assessment of the intra- and postoperative complication rates. RESULTS: Most of the lesions were benign (22, 71%), while nine strictures (29%) were malignant. Seven patients (23%) suffered from postoperative complications, five of which were infectious. The median pre- and postoperative calculated glomerular filtration rates were 66 ml/min/1.72m2 and 64ml/min/1.72m2, respectively. Success rate was 84%, defined as lack of need for re-operation or kidney drainage at the last followup. CONCLUSIONS: Upper- and mid-ureteral defects present a complex pathology necessitating experienced reconstructive surgical skills. Our data suggest good long-term results for primary urothelial-based reconstructions for these pathologies.

RESUMO

INTRODUCTION: Laparoscopic adrenalectomy is the surgical treatment for various adrenal diseases. The procedure is a common surgical practice for urologists and general surgeons and requires fundamental laparoscopic skills, nowadays common in the surgical education of residents in these practices. The aim of this study is to assess whether laparoscopic adrenalectomy differs in outcome between certified and trained surgeons and surgical residents and whether the learning curve changes the endpoint of the surgery. MATERIALS AND METHODS: A cohort retrospective study, including all adult patients who underwent laparoscopic adrenalectomy between June 2008 and June 2014, was conducted. Patients' demographic, clinical, and surgical data were recorded and analyzed. RESULTS: Fifty-three patients were included in the database (21 men, 32 women) with a mean age of 54 years (range 17-77). The cause for surgery was most commonly a benign adrenal tumor (27 patients, 50.9%) followed by large nonfunctioning adrenal tumors (16 patients, 30.1%), and adrenal cancer (8 patients, 15%). Eighteen patients (33.9%) were operated by residents (4-6 years into the residency) and 35 patients by a certified senior surgeon (66.1%). Left-sided adrenalectomy was preferred to right-sided adrenalectomy for resident tutoring (P = .03). Overall, intraoperative complications were seen in 6 patients (11.3%) and postoperative complications were seen in 9 patients (16.9%). There were no differences in operation time (P = .36), intraoperative complications (P = .76), postoperative complications (P = .96), and length of stay (P = .34) between the patients operated by senior residents and certified surgeons. CONCLUSION: Laparoscopic adrenalectomy is a complex surgical procedure that should be a part of the surgical training of surgery residents, as it is safe in guided hands.

RESUMO

INTRODUCTION: Rising levels of plasma creatinine in the setting of acute unilateral ureteral obstruction (AUUO) often reflects acute renal failure, mandating kidney drainage. We hypothesize that re-absorption of peri-renal urine extravasation (PUE), a common result of UUO, contributes significantly to the elevation in plasma creatinine, rendering the latter an inaccurate benchmark for renal function. We explored this hypothesis in a rat model of AUUO and PUE. METHODS: In total, 20 rats were equally divided into 4 groups. Groups 1 and 2 underwent unilateral ligation of the ureter with infiltration of rat's urine (index group) or saline (control) into the peri-renal space. Two additional control groups underwent peri-renal injection of either urine or saline without AUUO. Plasma creatinine levels were determined immediately prior to the procedure (T0), and hourly for 3 hours (T1, T2 and T3). Renal histology was investigated after 3 hours. RESULTS: Rats in the index group had a significantly greater increase in plasma creatinine levels over 3 hours compared to all other groups (p < 0.05). At T3, average plasma creatinine levels for the index group increased by 96% (0.49 ± 0.18 mg/dL) compared to 46% (0.23 ± 0.06 mg/dL increase) in the AUUO and saline group, and less than 15% rise in both the non-obstructed control groups. Our study limitations includes lack of spontaneous PUE and intraperitoneal surgical approach. CONCLUSIONS: Absorption of peri-renal urine in the presence of AUUO is a significant contributor to rising plasma creatinine levels, beyond those attributable to the obstruction alone, and may overestimate the extent of the true renal functional impairment.

RESUMO

BACKGROUND: The treatment for and long-term outcome of renal angiomyolipoma (AML) at high-risk for bleeding has not been determined. OBJECTIVE: To evaluate the complication rates and the long-term outcomes among patients treated by selective arterial embolization (SAE) for a large or symptomatic renal AML. DESIGN, SETTING, AND PARTICIPANTS: Forty-one patients with 48 kidneys containing AML were treated by SAE at a single tertiary academic center. INTERVENTION: All patients were treated by SAE and followed in a single center. MEASUREMENTS: SAE was performed with a mixture of 96% ethanol and polyvinyl alcohol particles. The variables used for the analysis included age, gender, presence of tuberous sclerosis (TS), and maximal tumor size prior to SAE. The study end points were recurrence of symptoms or bleeding, the need for re-embolization or surgery, and disease-specific survival. The mean follow-up period for the entire group was 4.8 yr. RESULTS AND LIMITATIONS: Mean patient age was 51 yr (range: 24-82), and the mean initial tumor size was 10.3 cm. Successful SAE was achieved in 40 patients (91%) with a minor complication rate of 11%. Avoidance of surgery was achieved in 96% of the kidneys. No retroperitoneal hemorrhage was noted during follow-up, and 98% of the kidneys were preserved during the follow-up period. No significant changes in creatinine levels were noted following SAE (P=0.27). The freedom from surgical treatment at 5 yr following SAE was 94% (95% CI, 89-99%). Disease-specific survival of the entire cohort was 100%. The study is a retrospective, and treatment was not given according to prospective protocol, and therefore sample bias may be present. CONCLUSIONS: SAE of renal AML has long-term efficacy in preventing hemorrhagic complications of renal AML, and preservation of the involved kidneys is amenable in both TS and sporadic cases.
