Long-term oncological outcomes of cystic renal cell carcinoma according to the Bosniak classification

OBJECTIVES

To evaluate the prognostic role of the Bosniak classification on the long-term oncological outcomes of cystic renal cell carcinomas.

MATERIAL AND METHOD

In a national multicentric retrospective study, we included patients treated surgically for localized cystic RCC from 2000 to 2010. Patients with a follow-up of less than 4 years, benign tumors, and ablative treatments were excluded. The primary outcome was disease-free survival.

RESULTS

152 patients met the inclusion criteria: Bosniak II (6%), III (53%), IV (41%), with a median follow-up of 61 (12-179) months. Characteristics of the population and the tumors were [median, (min-max)] age 57 (25-84) years old, tumor size 43 mm (20-280), RENAL score 7 (4-12), PADUA score 8 (5-14). Treatments were 55% partial nephrectomy, 45% radical nephrectomy, 74% open surgery, and 26% laparoscopy. In pathological report, cystic RCC were mainly of low grade (1-2, 77%) and low stage (pT1, 81%). The two main histological subtypes were conventional (56%) and papillary (23%) RCC. Staging at presentation and histological characteristics were similar between Bosniak III and IV, except for high grade which was more common in Bosniak IV (12 vs 36%, p < 0.01). The Bosniak classification was not predictive of the recurrence, as 5- and 10-year disease-free survival were similar in Bosniak III and IV (92% vs 92% and 84% vs 83%, p = 0.60).

CONCLUSION

The Bosniak classification is predictive of the risk of malignancy but not of the oncological prognosis. Regardless of the initial Bosniak categories, almost all cystic RCCs were of low stage/grade and had low long-term recurrence rate.

Prognostic factors after adrenalectomy for adrenal metastasis

PURPOSE

Very few studies have sought prognostic factors after adrenalectomy for metastasis. The aim of this study was to assess prognostic factors for oncological outcomes after adrenalectomy for adrenal metastasis.

METHODS

All adrenalectomies for metastases performed in seven centers between 2006 and 2016 were included in a retrospective study. Recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan-Meier method. Prognostic factors for CSS and RFS were sought by Cox regression analyses.

RESULTS

106 patients were included. The primary tumors were mostly renal (47.7%) and pulmonary (32.3%). RFS and CSS estimated rates at 5 years were 20.7% and 63.7%, respectively. In univariate analysis, tumor size (HR 3.83; p = 0.04) and the metastasis timing (synchronous vs. metachronous; HR 0.47; p = 0.02) were associated with RFS. In multivariate analysis, tumor size (HR 8.28; p = 0.01) and metastasis timing (HR 18.60; p = 0.002) were significant factors for RFS. In univariate analysis, the renal origin of the primary tumor (HR 0.1; p < 0.001) and the disease-free interval (DFI; HR 0.12; p = 0.02) were associated with better CSS, positive surgical margins with poorer CSS (HR 3.4; p = 0.01). In multivariate analysis, the renal origin of the primary tumor vs. pulmonary (HR 0.13; p = 0.03) and vs. other origins (HR 0.10; p = 00.4) and the DFI (HR 0.01; p = 0.009) were prognostic factors for CSS.

CONCLUSION

In this study, tumor size and synchronous occurrence of the adrenal metastasis were associated with poorer RFS. Renal origin of the primary tumor and longer DFI were associated with better CSS. These prognostic factors might help for treatment decision in the management of adrenal metastasis.

Sequential treatment with ProACT™ device implantation after male sling failure for male urinary incontinence

OBJECTIVES

There is no strong evidence for second line therapy after male sling failure for post-prostatectomy urinary incontinence (PPUI). We report the outcomes after periurethral balloons implantation for persistence or recurrence of mild PPI symptoms after male sling implantation.

METHODS

All patients implanted of a ProACT™ device (Uromedica, Inc., MN, USA) following I-STOP transobturator male sling (TOMS) failure, in a tertiary reference center between 2009 and 2016, were included. Patients were evaluated by 24-hour pad-test before and after implantation, and after each balloon repressurizing procedure. PGI-I and Likert scale patient satisfaction were estimated during a telephone interview conducted in 2016. Objective and subjective cure of urinary incontinence were defined by a 24-hour pad-test<8g and the use of zero or one pad per day, respectively.

RESULTS

Fourteen patients were included. Median follow-up was 34months [4-89]. Objective and subjective cure were 29% (n=4) and 57% (n=8), respectively. Median pad-test decreased from 95g [IQR: 130] to 34g [IQR: 83] (P=0.022). ProACT™ significantly decreased median pad-test by a factor 2.73 [1.19-6.29]. Eighty-eight percent patients were feeling a little better, much better or very much better and 77% were satisfied or very satisfied at the end of follow-up. Reoperation rate was 28% (n=4): 3 balloons were changed for caudally migration (n=2) or deflation (n=1) and 1 had a urinary sphincter implanted for severe UI.

CONCLUSIONS

ProACT™ is a safe and efficient treatment that can be used in second line therapy after TOMS failure for PPUI.

[Results of sacral neuromodulation on the urinary and fecal incontinence and sexuality in 20 women suffering from a double incontinence]

CONTEXT

Urinary and faecal incontinence (defining double incontinence) are common conditions, which are frequently associated and can altered sexuality. The effectiveness of the sacral nerve modulation (NMS) in the treatment of the urge urinary incontinence, faecal incontinence and double incontinence was shown.

OBJECTIVE

The present article aims to determine the impact of SNM on female sexual function in twenty women suffering from a double incontinence.

METHODS

All patients who received sacral neuromodulation for urge urinary and/or faecal incontinence between 2005 and 2010 and who still had the implant were included. Only 20 sexually active patients suffering from double incontinence were considered eligible. They completed a questionnaire on follow-up examinations.

RESULTS

The initial indication of NMS was the urge urinary incontinence for 15 patients and the faecal incontinence for five patients. Ten patients (50%) were improved on two incontinence. All patients preserved sexual activity after the treatment of NMS. NMS improves the quality of sexual activity in 45% patients. The numbers of urinary and faecal episodes of incontinence are decreased respectively for 50% and 15% patients during sexual activity. The quality of sexual's life and orgasm score are significantly increased in the group of patients improved on the DI.

CONCLUSION

This study confirms the effectiveness of NMS in the treatment of double incontinence which half patients are improved on the two incontinence. This study shows that improvement of urinary or faecal incontinence could have a positive impact on sexuality of these patients, especially for patients improved double incontinence. It is difficult to know if these results are related to its direct action on the neurological ways of sexual function or on its benefit on the continence.

[HoLEP learning curve: Toward a standardised formation and a team strategy]

AIM

Holmium laser enucleation of prostate (HoLEP) is renowned for the difficulty of its learning curve. Our aim was to evaluate the interest of a three-step tutorial in the HoLEP learning curve, in a university center.

METHODS

It is a retrospective, monocentric study of the 82 first procedures done consecutively by the same operator with a proctoring in early experience and after 40 procedures. For all patients were noted: enucleation efficiency (g/min), morcellation efficiency (g/min), percentage of enucleated tissue (enucleated tissue/adenome weigth evaluated by ultrasonography. g/g), perioperative morbidity (Clavien), length of hospital stay, length of urinary drainage, functional outcomes at short and middle term (Qmax, post-void residual volume [PVR], QOL scores and IPSS at 3 and 6months).

RESULTS

Enucleation and morcellation efficiency were significantly higher after the second proctoring (0.87 vs 0.44g/min; P<0.0001 and 4.2 vs 3.37g/min, P=0.038, respectively) so as the prostatic volume (43.5 vs 68.1mL, P=0.0001). Percentage of enucleated tissue was higher in the second group, however, the difference was not significant (69.5% vs 80.4%, P=0.03). Per- and postoperative complications, hospital length of stay, urinary drainage length and functional results at 3 and 6months were not significantly different.

CONCLUSION

The learning curve did not interfere with functional results. The second proctoring was essential to us in order to grasp the technique. These data underlined the necessity of a pedagogic reflexion in order to built a standardized formation technique to the HoLEP.

[Renal Trauma]

INTRODUCTION

Renal traumas are common, observed in 10% of patients with abdominal trauma. Most renal traumas are blunt, resulting from a direct hit or from an abrupt deceleration.

MATERIAL AND METHODS

We realized a synthesis of renal trauma management for nurses.

RESULTS

Clinical presentation often encompasses gross hematuria and lumbar pain. The best diagnostic tool is computed tomography (CT) urogram. Based on CT urogram images, renal traumas are classified according to the American Association for the Surgery of Trauma (AAST) classification in five grades of increasing severity. The management is conservative in the vast majority of cases and has been largely simplified over the past few years, being now mostly based on observation. Radiological interventional and endoscopic procedures are used only in very selected cases and surgical exploration has become extremely rare.

CONCLUSION

The prognosis has also considerably improved and renal trauma rarely result in death or loss of the kidney nowadays.

[French resident's performance on laparoscopic surgery box trainer: 7-year results of pelvitrainer contests]

OBJECTIVES

The study objectives were to analyze the resident's laparoscopic surgery performance in order to build a self-assessment data set, to identify discriminatory exercises and to investigate the suturing time changes.

METHODS

From 2007 to 2014, the French Association of Urologist in Training (AFUF) organized 7 pelvitrainer contests. Participant scores on 11 laparoscopic surgery exercises were evaluated.

RESULTS

Sixty-six residents participated to these contests and performed 11 exercises each. Twenty-two (33.3 %) participants were beginners, 26 (39.4 %) intermediates et 18 (27.3 %) experienced. The participant scores were gathered into a data set including the average time per exercise. We found a time scoring improvement related to the resident experience for all exercises. A significant decline in time was noted for exercise 8 and 9 between beginners and intermediates (139s [±71]), (173.9s [±118.3]) and between beginners and experienced (80.6s [±26.7]), (94,1s [±42.7]) with a P<0.05. The correlation coefficient for the exercise 11 duration (vesico-uretral anastomosis) was 0.04 over a 7-year period (P=0.44).

CONCLUSION

The study provided a data set on 11 laparoscopic surgery tasks which can be consulted by all residents as a reference in a self-assessment process. Two exercises (8 and 9) discriminated beginners from intermediates and experienced groups and could be used as a benchmark ahead of an operating room procedure. The vesico-uretral anastomosis duration (exercise 11) did not improve significantly between 2006 and 2014.

[External sphincterotomy in neurological patients: A monocentric experience]

AIM

The aim of this study was to assess the feasibility, efficacy and tolerance of Greenlight™ and Holmium sphincterotomy for treating detrusor-sphincter dyssynergia.

METHODS

All men treated with this two techniques between may 2012 and june 2015 were analyzed. Preoperative evaluation included kidney ultrasound scan, urodynamic, retrograde and voiding urethrocystography. Postoperative assessment was composed of a post-void residual volume measurement when the urethral catheter was removed and 1 year after the procedure, a retrograde and voiding urethrocystography at 3 months and telephonic Likert scale questionnaire.

RESULTS

Twelve patients were operated with Greenlight™ and 12 with Holmium. Eleven had a memocath urethral stent preoperatively. Post-void residual volume median for both techniques was 285 cc preoperatively vs 137.5 cc postoperatively (P<0.001). Likert scale global satisfaction was 75%. Five stenosis (20.8%) were observed within a median of 4 months.

CONCLUSION

Greenligth™ and Holmium procedures are efficient techniques with low morbidity. However, superiority toward monopolar incision remains to be demonstrated through complementary studies.

[Prognostic factors for metastatic renal cell carcinoma treated with second-line targeted therapies]

OBJECTIVE

To assess the prognostic value of clinical and biological features in patients treated with second-line targeted therapies (TT) for a metastatic renal cell carcinoma (mRCC).

MATERIAL AND METHODS

A retrospective study was performed including 60 patients treated with second-line TT from 2006 to 2013. Clinical and biological features were collected, including TT-induced toxicities, Heng and MSKCC prognostic scores, and renal function. Overall survival (OS) and progression-free survival (PFS) were assessed using univariate and multivariate analysis.

RESULTS

The median age was 61 years [39-81]. MSKCC and Heng scores were significantly prognostic for OS and PFS (P<0.05). Hypo-albuminemia, anemia and brain metastasis were associated with poorer OS and PFS (P<0.05). Severe induced toxicities had a prognostic impact with higher OS (26 months vs 10 months, P=0.003) and PFS (5 months vs 4 months, P=0.047). Renal function impairment at the initiation of the second line was also associated with higher survival (OS=24 months vs 9 months, P=0.035 and PFS=7 months vs 4 months, P=0.043). On multivariate analysis, induced toxicity was found as an independent factor of good prognosis for OS (HR=0.36; P=0.01).

CONCLUSION

Our results suggested that renal function impairment and TT-induced toxicities in the second line of treatment for mRCC have a potential prognostic interest as it had previously been reported for the first line of TT.

Is intraoperative heparin during renal transplantation useful to reduce graft vascular thrombosis?

OBJECTIVES

The standard treatment for end-stage renal disease is renal transplantation. As vascular anastomoses are performed during the surgery, it may expose to a risk of vascular thrombosis. This raises the question of using intravenous heparin during the procedure. The purpose of this study was to compare the incidence of renal transplant vascular thrombosis in the perioperative period based on whether the patients received or not intraoperative heparin.

METHODS

A single center retrospective study was conducted on a cohort of consecutive patients who underwent renal transplantation between 2011 and 2015. Patients were divided into two groups: patients not receiving heparin vs. receiving heparin at the dose of 0.5mg/kg. A Doppler ultrasound was performed at day one postoperatively to assess the occurrence of vascular thrombosis. Hemorrhagic complications and the need for postoperative transfusion were also assessed.

RESULTS

In total, 261 patients were included. Fifty-one patients received heparin (19.5%). Patient's baseline characteristics were comparable between the groups. No significant difference was found regarding the incidence of vascular thrombosis (6% for both groups, P=1). In addition, no difference was found regarding hemorrhagic complications requiring surgical revision (P=1) as well as early postoperative transfusion rate (P=0.57).

CONCLUSIONS

Our results suggest that intraoperative IV heparin doesn't improve the risk of vascular thrombosis following renal transplantation. However, intraoperative IV heparin was not significantly associated with a higher rate of hemorrhagic complications suggesting that heparin can be safely used if required in some selected patients at higher risk of thrombosis.

[Botulinum toxin A intradetrusor injections in consultation: single center experience during 2 years]

OBJECTIVES

In departments of urology, intradetrusor botulinum toxin injections are routinely performed in ambulatory outpatient clinic. The aim of the study was to assess the satisfaction level of patients treated with this technique.

PATIENTS AND METHODS

A satisfaction questionnaire was carried out by telephone for all patients treated in ambulatory outpatient clinic from 2009 to 2010.

RESULTS

Twenty-six patients were treated in consultation during the studied period for a total of 46 sessions of injections. The average age was 48.81 (±16.78) years. An injection programme containing 20 or 30 points was performed after a local anesthetic. Twenty patients answered the questionnaire. As regards the organization of the injections, 12 patients (60%) declared to have been satisfied and seven very satisfied (35%). Eight patients (40%) were very satisfied with the management of the pain and six (30%) satisfied versus only one (5%) not satisfied at all. For the time spent in the hospital during the injections, 10 (50%) were satisfied and seven (35%) very satisfied. Only 4 patients (20%) would have preferred to be hospitalized in an outpatient facility. In cases of new injections, 18 (90%) patients would have preferred an identical coverage. Finally, 17 (85%) would recommend this procedure to one of their close relations.

CONCLUSION

Our results showed that the majority of patients were completely satisfied with the injection programme. However, as patients are not currently covered by the national health system for these injections, this might hinder the development of this procedure.

[BCG strain shortage from 2012 to 2014: Evaluation of its impact on the management of patients with high-risk NMIBC]

INTRODUCTION

BCG instillations are the gold-standard treatment for high-risk non-muscle-invasive bladder cancer (NMIBC) with a decreased risk of tumor recurrence and muscle infiltration. From 2012 to 2014, a stock shortage of the Connaught strain has led to the cessation of supply for immucyst in France. The objective of this study was to evaluate the potential impact of BCG shortage on the management of patients with NMIBC.

PATIENTS AND METHODS

We conducted a retrospective single-center study including patients followed from May 2005 to May 2015 with a high-risk NMIBC (primo-diagnosis). Patients were separated into two groups: not impacted by the shortage (NISG: 56 patients) and impacted by the shortage (ISG: 53 patients). Data on tumour recurrence (RFS), muscle progression (PFS) and overall and specific survival (OS and SS) were also analysed.

RESULTS

The BCG induction schedule could not be carried out in 20.8% of cases in the ISG compared to only 5.3% of cases in NISG (P=0.02). Similarly, the maintenance treatment was incomplete for 56.6% of cases versus 37.5% in NISG (P=0.047). Nevertheless, it should be underlined that very high-risk NMIBC received a complete induction BCG schedule. The ISG seems to have benefited with the evolution of the guidelines with the use of diagnosis bladder fluorescence but without significant difference on the rate of second look bladder trans-uretral resection. The cystectomy rate was higher in ISG. No significant difference in RFS, PFS, OS, and SS between the two groups.

CONCLUSION

In our experience, RFS, PFS, OS or SS were not impacted by the BCG shortage. These data may be explained by a better selection of very high-risk patients including the recommended BCG schedule and more frequently the use of diagnosis bladder fluorescence.

[Treatment of pseudoaneurysm following partial nephrectomy]

BACKGROUND

Partial nephrectomy (PN) has become the gold standard for the treatment of small tumors confined to the kidney. As result, the number of PN procedures increased during the last years. Subsequently, we have more often to deal with the complications of this surgery. Among these, pseudoaneurysms are rare but potentially life-threatening due to a risk of bleeding. Therefore, pseudoaneurysms have to be treated according to a relevant strategy.

METHODS

We performed a literature review of the cases of pseudoaneurysm after PN was reported as well as a focus on the different treatment strategies and their outcomes.

RESULTS

The incidence of pseudoaneurysm is low, ranging from 0.5% to 4%. Radio-embolization represents the gold standard treatment, used in 98% of the cases reported in the literature, allowing high success rate and rare morbidity. However, in some selected cases, surveillance could be an alternative.

Effect of obesity on histological type of renal tumor: the Uroccr study 69

Renal cell carcinomas (RCC) are increasing worldwide and obesity is one of its recognized causal factor. Obesity thus could be differently associated with the different histologic types of renal tumors and also impact prognosis and patient care.

PURPOSE

the primary objective was to evaluate an association between obesity and histological type of RCC. The secondary objective was to assess if there was an effect of obesity on tumor characteristics.

METHODS

a multicenter comparative descriptive study was carried out in nearly 30 french hospitals. Histological features of operated RCC of patients included between 2007 and 2020 were compared according to their BMI. Obesity was defined as a BMI >=30 kg/m2, with a p < 0.05.

RESULTS

in total, 6749 RCC were analyzed, including 1687 (25%) from obese patients. This population was more frequently diabetic (61% versus 41%, p < 0.001) and hypertensive (27% versus 11%, p < 0.001). Regarding histological evaluation, the obese group presented more clear cell carcinoma. Other types presented Odd Ratios below 1 on multivariate analysis, p < 0.01 except for type II papillary RCC. Tumor size (pT) and nuclear ISUP grade were both lower when BMI was above 30 kg/m2 : 72.4% of size pT 1-2 versus 68.5% (p = 0.026) and 50% of nuclear ISUP grade 1-2 versus 43.3% for the non-obese group (p < 0.0001). There was no difference in survival due to an insufficient number of events.

CONCLUSION

in this large cohort study, we report novel data on a positive association between obesity and histological type of RCC, in particular clear cell RCC.
