Abstract
INTRODUCTION The aim of this study was to assess the impact of the acquisition of a Da Vinci® robot on the use and outcomes of partial nephrectomy (PN). PATIENTS AND METHODS It was a single center retrospective study including 280 patients who underwent PN from January 2006 to May 2013. The number of PN, tumors and patients' characteristics and perioperative outcomes have been assessed over 3 periods defined according to the main surgical approach: 2006-2008 (open PN), 2008-2010 (laparoscopic PN) and 2010-2013 (robotic PN). RESULTS Over the study period, the surgical approach has changed significantly in favor of minimally-invasive surgery and especially robotic approach. The PN/nephrectomy rate has also evolved to a higher proportion of PN over radical nephrectomy (P=0.002). No significant difference was noted between the three periods in terms of tumor size but there was a higher rate of highly complex tumors (RENAL score≥10) during the last period (10.7%; 18.6% and 33.2%; P=0.04). Warm ischemia time increased from 2006-2008 to 2008-2010 (26 vs. 23minutes) but decreased thereafter during the robotic era (14.5minutes; P<0.001). Regarding postoperative outcomes, the only change was a decreased length of stay over time (P=0.003). CONCLUSION In this single center series, the robotic approach was associated with a spread of PN and with an improvement of nephron-sparing surgery outcomes. LEVEL OF EVIDENCE 4.

Abstract
INTRODUCTION Upper tract urinary carcinoma (UTUC) pT3 tumors are a heterogeneous entity including tumors invading the renal parenchyma, tumors with peripelvic fat invasion or peri-ureteral fat invasion. The aim of this study was to evaluate the prognostic significance of these three different groups of pT3 tumors. PATIENTS AND METHODS Between 1998 and 2012, 205 patients with UTUC were operated in two centers, including 52 patients with pT3 tumor stage. pT3 tumors were divided into three groups: peri-ureteral fat invasion (pT3U, n = 16), peripelvic fat invasion (pT3G, n = 21), and renal parenchyma invasion (pT3P, n = 15). The prognostic significance of the type of tumor infiltration was evaluated on specific and disease-free survival. RESULTS Median follow-up was 18.9 months [6-133.4]. In univariate analysis, renal parenchyma invasion was associated with a better prognostic in both specific (P = 0.026) and disease-free survival (P = 0.031) compared with peripelvic or peri-ureteral fat invasion. Mutivariate analysis retained the pT3 subgroup as an independant prognostic factor in both specific and disease-free survival (P = 0.02). CONCLUSION pT3 tumors with renal parenchyma invasion had a better prognosis than those with peripelvic or peri-ureteral fat invasion. The heterogeneity of the pT3 group should be taken into account to improve the care of patients.

Abstract
OBJECTIVE To evaluate the feasibility and morbidity of laparoscopic nephrectomy in patients with autosomal dominant polycystic kidney disease (ADPK). PATIENTS AND METHOD This is a retrospective multi-centre study (University Hospitals of Lyons, Toulouse, Nantes and Rennes). Sixty-eight patients who had undergone laparoscopic nephrectomy for polycystic kidney disease between November 1999 and May 2009 were included. This involved unilateral nephrectomy 64 cases, one-stage bilateral in one case and two-stage bilateral in three cases. RESULTS The mean operating time was 218±74min (100-420) Conversion was necessary in 7 cases. The mean weight of the removed kidney was 1291±646g (240-3400). We regret to report 20 postoperative complications, including one death on postoperative day 50, following an abscess in the renal pelvis, 6 retroperitoneal haemoatomas and 5 arteriovenous fistula thromboses. Postoperative analgesia involved PCA treatment with morphine for a mean period of 1.59±0.8 days (0.5-4). The mean length of hospital stay was 8.3±6.1 days (3-50). CONCLUSION This study shows the feasibility of the laparoscopic approach for nephrectomy in ADPK. This procedure should be performed by experienced laparoscopic surgeons. Indeed, the complication rate is moderate but there is still a risk of severe complications. LEVEL OF EVIDENCE 5.

Abstract
Background: Angiogenesis is essential for tumour growth and metastasis. There are conflicting reports as to whether microvessel density (MVD) using the endothelial marker CD105 (cluster of differentiation molecule 105) in clear-cell renal cell carcinomas (ccRCC) is associated with prognosis. Recently, CD105 has been described as a RCC cancer stem cell marker. Methods: A total of 102 ccRCC were analysed. Representative tumour sections were stained for CD105. Vascularity (endothelial CD105) was quantified by MVD. The immunohistochemistry analysis detected positive (if present) or negative (if absent) CD105 tumoral staining. This retrospective population-based study was evaluated using Kaplan–Meier method, t-test and Cox proportional hazard model. Results: We found that the expression of endothelial CD105 (MVD) negatively correlated with nuclear grade (P<0.001), tumour stage (P<0.001) and Leibovitch score (P<0.001), whereas the expression of tumoral CD105 positively correlated with these three clinicopathological factors (P<0.001). In multivariate analysis, tumoral CD105 was found to be an independent predictor of poor overall survival (P=0.002). Conclusions: We have shown for the first time that tumoral CD105 is an independent predictive marker for death risk and unfavourable prognosis in patients with ccRCC after curative resection.

Abstract
Surgery remains the treatment of choice for locally advanced or metastatic renal cell carcinoma. However, the contribution of targeted therapies has recently significantly impacted recurrence-free survival in metastatic patients, challenging in some cases the real interest of nephrectomy. Waiting for the results of CARMENA trial, assessing the impact of cytoreductive nephrectomy on survival, neoadjuvant and adjuvant strategies are emerging. In locally advanced disease, adjuvant therapy should be considered if the patient is considered at high risk of progression, and therefore require its inclusion in a prospective randomized trial. Neo-adjuvant anti-angiogenic strategies show a quite modest improvement in resectability of primary tumor, while allowing performing translational research. However, many questions remain on hold in terms of precise indications, choice of drugs, toxicity and optimal dosing schedule. All these questions explain the current development of phase III trials.

Abstract
De novo tumors in renal allografts are rare and their prevalence is underestimated. We therefore analyzed renal cell carcinomas arising in renal allografts through a retrospective French renal transplant cohort. We performed a retrospective, multicentric survey by sending questionnaires to all French kidney transplantation centers. All graft tumors diagnosed after transplantation were considered as de novo tumors. Thirty-two centers participated in this study. Seventy-nine tumors were identified among 41 806 recipients (Incidence 0.19%). Patients were 54 men and 25 women with a mean age of 47 years old at the time of diagnosis. Mean tumor size was 27.8 mm. Seventy-four (93.6%), 53 (67%) and 44 tumors (55.6%) were organ confined (T1-2), low grade (G1-2) and papillary carcinomas, respectively. Four patients died of renal cell carcinomas (5%). The mean time lapse between transplantation and RCC diagnosis was 131.7 months. Thirty-five patients underwent conservative surgery by partial nephrectomy (n = 35, 44.3%) or radiofrequency (n = 5; 6.3%). The estimated 5 years cancer specific survival rate was 94%. Most of these tumors were small and incidental. Most tumors were papillary carcinoma, low stage and low grade carcinomas. Conservative treatment has been preferred each time it was feasible in order to avoid a return to dialysis.

Abstract
Melanoma is a slowly growing malignancy, with potential distant metastasis at various sites. In this article, we reported three original cases of melanoma metastases in the upper urinary tract, and we achieved a literature review. Symptoms are inconstant and non-specific (pain or haematuria). Nephroureterectomy is performed in the majority of cases. Even if this metastatic location remains uncommon, it should be timely detected in order to allow an appropriate management and to improve the prognostic of melanoma.

Abstract
OBJECTIVE To determine the prognostic significance of the neutrophil gelatinase-associated lipocalin (NGAL) and the matrix metalloproteinase 9 (MMP-9) in clear cell renal cell carcinoma (CCRCC). PATIENTS AND METHODS NGAL and MMP-9 expression were quantified by immunohistochemistry in clear renal cell carcinoma tissues and in sera by Enzyme Linked Immunosorbent Assay (Elisa). Results were associated with clinicopathologic data. RESULTS Seventy-four patients operated for CCRCC in Rennes between 2003 and 2009 were included. High concentrations of NGAL-MMP-9 complex in serum were associated with short progression free survival (PFS) (33.3 months versus 47.3 months, P=0.016) and poor overall survival (42.5 months versus 51.9 months, P<0.047). High NGAL concentrations in serum were also associated with shorter PFS (13.6 months versus 41.6 months, P=0.04). However, no NGAL expression was observed in renal tumor cells. Interestingly, NGAL was expressed by neutrophils infiltrating CCRCC and we showed that the density of NGAL expressing neutrophils was associated with pejorative PFS and survival (36.9months versus 56.1 months, P<0.006). CONCLUSION In this study, we showed the pejorative significance of NGAL-MMP-9 complex and NGAL rates in serum of CCRCC. We also confirmed that density of NGAL expressing neutrophils in CCRCC was associated with poor outcome.

Abstract
Background: The growth factor Angiotensin-2 signals through Angiotensin receptor type 1 (AT1-R) in a broad range of cell types and tumours and through the type-2 receptor (AT2-R) in a more restricted group of cell types. Although numerous forms of cancer have been shown to overexpress AT1-R, expression of AT1-R and AT2-R by human renal clear-cell carcinoma (RCCC) is not well understood. In this study, the expression of both angiotensin receptors was quantified in a retrospective series of RCCC and correlated with prognostic factors. Methods: Angiotensin receptor type 1 and AT2-R expressions were quantified on tumour tissues by immunohistochemistry (IHC), western blot and quantitative reverse transcriptase PCR (qRT–PCR). IHC results were correlated to Fuhrman's grade and patient progression-free survival (PFS). Results: A total of 84 RCCC were analysed. By IHC, AT1-R and AT2-R were expressed to a greater level in high-grade tumours (AT1-R: P<0.001, AT2-R: P<0.001). Univariate analysis showed a correlation between PFS and AT1-R or AT2-R expression (P=0.001). By multivariate analysis, only AT2-R expression correlated with PFS (HR 1.021, P=0.006) and cancer stage (P<0.001). By western blot, AT1-R and AT1-R were also found to be overexpressed in higher Fuhrman's grade (P<0.01 and P=0.001 respectively). By qRT–PCR, AT1-R but not AT2-R mRNA were downregulated (P=0.001 and P=0.118, respectively). Conclusion: Our results show that AT1-R and AT2-R proteins are overexpressed in the most aggressive forms of RCCC and that AT2-R expression correlates with PFS. AT1-R or AT2-R blockage could, therefore, offer novel directions for anti-RCCC therapy.

Abstract
INTRODUCTION Optical spectroscopy refers to a group of novel technologies that uses interaction of light with tissues to analyze their structure and chemical composition. The objective of this article is to describe these technologies and detail their potential for assessing urological tumors. MATERIAL AND METHODS It has been shown that optical spectroscopy can accurately analyse multiple solid tumors. Several publications specifically aimed at assessing prostate cancers, renal carcinomas and urothelial tumors. RESULTS There are three types of spectroscopy that all use light focussed on a tissue and thereafter collect a specific reflected optical signal. Optical spectroscopy can differentiate benign (adenoma or inflammation) and malignant (adenocarcinoma) prostatic tissues. It can also distinguish normal bladder tissue from inflammatory or cancerous cells. Regarding renal tumors, spectroscopy can identify normal and tumoral tissue and differentiate benign and malignant tumors. Its diagnostic accuracy is about 85%. However, reported studies only concentrate on in vitro or ex vivo specimen and the numbers of patients are quite small. CONCLUSION Optical spectroscopy can be envisioned as an "optical biopsy" tool. Potential applications in the clinical field are promising. Larger studies on in vivo specimen need to be undertaken to confirm phase I preliminary reports.

Abstract
During the recent congress of urology and oncology key topics discussed were the evolution of survival data in metastatic kidney cancer which median is now around 40 months, persistent questions about the role of nephrectomy, including access to the systemic treatment of nephrectomized patients and tumor resectability induced by systemic therapies, the emergence of new prognostic models which are adapted to new therapeutic standards, and the emergence of promising new drugs including pazopanib. This article describes these advances.

Abstract
Nowadays, most of renal cancers are incidental tumors less than 4 cm. Prevalence of lymph node involvement is low and does not require a systematic lymphadenectomy as described by Robson in the 1960s. Radiologic progress and particularly CT scan describe with high precision lymph node involvement in the initial work-up. In renal cancer with a high risk of recurrence, lymphadenectomy has a pronostic interest and therapeutic role in rare situations where lymph node involvement is isolated. In metastatic patients, the role of cytoreductive nephrectomy has to be assessed.

Abstract
PURPOSE Our objective was to compare oncologic results of nephron sparing surgery (NSS) versus radical nephrectomy (RN) in T1aN0-x M0 papillary renal cell carcinoma (PRCC). PATIENTS AND METHODS We retrospectively reviewed 277 patients treated for a pT1aN0M0 PRCC selected from an academic database from 12 centres. We compared the clinico-pathological features by using Chi-square and Student statistical analyses. Survivals analyses using Kaplan-Meier and Log-rank models were performed. RESULTS The two groups were composed by 186 patients treated by NSS and 91 by RN. The TNM stage was fixed and the two groups were, in terms of age and Fuhrman grade, comparable. Median age at diagnosis was 59 years (27-85). Median tumor size was 2.7 cm (0.4-4). The average follow-up was 49 months (1-246). Very few events arose in both groups: two local recurrences were observed in the NSS group (1.07%), three patients died of cancer in the NSS treated group (1.6%) and five in the RN treated group (5.5%). The five and 10 cancer-specific survival rate were comparable in the two groups (98% vs. 100% and 98% vs. 97%). The specific survival curves were perfectly similar for both groups (log rank test, p=0.25). CONCLUSION NSS is equivalent to RN as far as oncologic control of pT1aN0M0 PRCC is concerned.

Abstract
Treatment of metastatic kidney cancer in elderly subjects is identical to treatment of younger subjects. Whereas cytokines were classically contraindicated in patients over 70 or 75 years (notably IL2), new targeted therapies have been evaluated and found to be usable with no age limit, and all of the phase III studies have included patients 80 years old and older. Overall, there seems to be no difference in efficacy based on age (except perhaps for temsirolimus). As for tolerance, it is satisfactory for all therapies. Dose reduction is slightly more frequent, which calls for caution, notably with sunitinib, for which a direct correlation between the dose administered and efficacy has been reported. Given the data available today, no dose adaptation in relation to age is recommended in metastatic renal cancer.

Abstract
Background: The von Hippel–Lindau gene (VHL) alteration, a common event in sporadic clear-cell renal-cell carcinoma (CCRCC), leads to highly vascularised tumours. Vascular endothelial growth factor (VEGF) is the major factor involved in angiogenesis, but the prognostic significance of both VHL inactivation and VEGF expression remain controversial. The aims of this study were to analyse the relationship between VHL genetic and epigenetic alterations, VHL expression and VEGF tumour or plasma expression, and to analyse their respective prognostic value in patients with CCRCC. Methods: A total of 102 patients with CCRCC were prospectively analysed. Alterations in VHL were determined by sequencing, Multiplex Ligation-dependent Probe Amplification (MLPA) and methylation-specific MLPA. Expression of pVHL and VEGF was determined by immunohistochemistry. Plasma VEGF was measured by enzyme-linked immunosorbent assay (ELISA). Results: VHL mutation, deletion and promoter methylation were identified in 70, 76 and 14 cases, respectively. Overall, at least one VHL-gene alteration occurred in 91 cases (89.2%). Both VEGF tumour and plasma expression appeared to be decreased in case of VHL alteration. Median progression-free survival and CCRCC-specific survival were significantly reduced in patients with wild-type VHL or altered VHL and high VEGF expression, which, therefore, represent two markers of tumour aggressiveness in CCRCC. Conclusion: Stratifying CCRCCs according to VHL and VEGF status may help tailor therapeutic strategy.

Abstract
Since 2004, the treatment of metastatic renal cell carcinoma is in deep mutation. Before, the Management was mostly relying on the use of cytokines in association with radical nephrectomy. From 2004, studies of new antiangiogenic molecules, acting on the pVHL-HIF way, VEGF, PDGF or tyrosine-kinase receptors have modified the management of metastatic patients. Antiangiogenic agents improve progression-free survival as shown with sunitinib, in first line treatment, or sorafenib, as second line treatment. The m-TOR inhibitors (Temsirolimus), can be used with a benefit on overall survival in case of poor prognosis renal cell carcinoma or non clear cell carcinoma. Lastly, bevacizumab, an antibody re-combining humanized monoclonal, is able to target VEGF. Side effects are different for each molecule and are not negligible. Nevertheless, the place of these molecules have to be defined in the sequence of the treatment.

Abstract
In case of a single renal cell carcinoma strictly located in the kidney, the radical nephrectomy remains the treatment of choice. However, it has been estimated that nearly 30 to 40 % of renal cell carcinoma are about to recur after primitive surgery. In certain cases, conservative surgery can be discussed as an alternative to radical treatment, especially in case of exophytic renal tumour or less than 4 cm in diameter. New ablative techniques (radiofrequency and cryoablation) have shown promising results but the follow-up is still very limited. French national recommendation regarding kidney cancer have been updated in 2007 and following the development of clinical trials using antiangiogenic agents. Regarding the use of antiangiogenic agents, several points have to be taken into account: existence of renal cell carcinoma, presence of metastasis, number of metastasis, location and risk factor prognosis determination.

Abstract
The indications for partial or radical nephrectomy of a kidney tumour are based on tumour diameter with a cut-off of 4cm. Tumour diameter has been demonstrated to be a continuous prognostic parameter which, ideally, should be integrated into multivariate prognostic models. The 4cm cut-off is reasonable, but was established pragmatically on the basis of series comprising selection biases. At least six series now question the validity of this cut-off, and some of them have demonstrated that partial nephrectomy and radical nephrectomy are equivalent in terms of cancer control for pT1b tumours. Furthermore, the excess mortality induced by broader indications for partial nephrectomy appears to be acceptable. These data appear to suggest that the feasibility of partial nephrectomy should be considered regardless of tumour diameter before proposing the indication for radical nephrectomy.

Abstract
When announcing the diagnosis of renal cell carcinoma, the urologist and the patient can wonder about the waiting time for surgically treating the cancer. This review aimed to investigate the scientific facts to determine the time between the diagnosis of kidney cancer and the achievement of surgically. The natural history of kidney cancer has been the fundamental of the therapeutic management. The time between diagnosis and surgical treatment depends on the conditions under which the diagnosis was established. Patients with symptomatic cancer or discovered at metastatic stage had to be treated quickly. In case of incidental diagnosis, evaluation of tumors has resulted in the selection of patients who can wait several months between diagnosis and surgical treatment of kidney cancer on the condition watchful waiting. The modalities of this assessment, radiological and anatomopathological, must be validated by further studies.

Abstract
Anti-tumour T cell response requires antigen presentation via efficient immunological synapse between antigen presenting cells, e.g. dendritic cells (DC), and specific T cells in an adapted Th1 cytokine context. Nine renal cell carcinoma (RCC) primary culture cells were used as sources of tumour antigens which were loaded on DC (DC-Tu) for autologous T cell activation assays. Cytotoxic activity of lymphocytes stimulated with DC-Tu was evaluated against autologous tumour cells. Assays were performed with 75 grays irradiated tumour cells (Tu irr) and with hydrogen peroxide +/- heat shock (Tu H(2)O(2) +/- HS) treated cells. DC-Tu irr failed to enhance cytotoxic activity of autologous lymphocytes in seven of 13 assays. In all these defective assays, irradiated tumour cells displayed high interleukin (IL)-6 and vascular endothelial growth factor (VEGF) release. Conversely, when tumour cells released low IL-6 levels (n = 4), DC-Tu irr efficiently enhanced CTL activity. When assays were performed with the same RCC cells treated with H(2)O(2) + HS, DC-Tu stimulation resulted in improved CTL activity. H(2)O(2) + HS treatment induced post-apoptotic cell necrosis of tumour cells, totally abrogated their cytokine release [IL-6, VEGF, transforming growth factor (TGF)-beta1] and induced HSP70 expression. Taken together, data show that reduction in IL-6 and VEGF release in the environment of the tumour concomitantly to tumour cell HSP expression favours induction of a stronger anti-tumour CTL response.

Abstract
Rupture of posterior urethra is usually seen in major traumas with associated pelvic fractures. Clinical presentation classically associates blood at the uretral meatus and urinary retention. Urinary diversion should be achieved by suprapubic puncture and major associated traumatic injuries (abdominal, orthopaedic, and neurological lesions) must be treated prior to urological management. Retrograde uretrocystography is performed a few days later in order to localize and classify the urethral lesion. Treatment of posterior urethral ruptures has evolved over the years. Immediate open repair is no longer recommended. The supra-pubic catheter can be left in place until resorption of the pelvic hematoma. Obliteration occurs in 100% of the cases and is treated by open surgery at 3 months. More and more patients are treated by early endoscopic realignment which has diminished by half the incidence of urethral strictures. Impotence and incontinence secondary to trauma or surgery occur in 20% and 10% of the patients respectively. Long term follow-up should be achieved in every patient.

Abstract
One of the goal of the Nephron-Sparing Surgery preoperative planning is to delineate as exactly as possible the renal carcinoma and to specify its relations to the renal arterial, venous and collecting system anatomy. The classical preoperative imaging system is the spiral CT urography, which gives successive 3D acquisitions of complementary information about the kidney anatomy. The fusion of this information can be achieved by intra-patient registration techniques. However, because the kidney is difficult to demarcate from the liver or the spleen, a partial information registration technique should be used. In our paper we propose a methodology based on spherical harmonics, which can be used for partial information registration and also for the 3D kidney form modeling.

Abstract
T1G3 tumours are the most aggressive superficial tumours of the bladder, with a high risk of recurrence and progression. Complete endoscopic resection of the tumour is the first diagnostic and therapeutic step in T1G3 management. A second resection should be done at 1 month to avoid residual tumour and misdiagnosis of a muscle infiltrative cancer. As a result of treatment by instillations of Calmette and Guérin bacillus following endoscopic resection, a 5-year survival rate of 80% has been reported, with 50 to 60% of bladder preservation. BCG is the only conservative treatment that has proven effectiveness on both tumour recurrence and progression. Long term protocols seem to give the best results. Endovesical chemotherapy is not commonly used as its impact on progression has not been demonstrated. Radical cystectomy can be chosen as first line treatment in patients with particularly aggressive tumours. Long term and close surveillance should be achieved in every patient.

Abstract
BACKGROUND Over recent decades, recurring efforts have been devoted to developing testicular cell or tissue cultures for basic and clinical research. However, there remains much confusion, particularly concerning the fate of human germ cells in culture. OBJECTIVE To reassess the status of human testicular cell types as well as the ability of germ cells to divide and differentiate in organotypic culture. METHODS Human testicular fragments were maintained for 2 weeks in culture. The viability and functionality of testicular cells were assessed using light and electronic microscopy, apoptotic cell labelling, 5-bromo-2'-deoxyuridine (BrdU) incorporation, immunohistochemistry and quantitative PCR against specific cell markers. RESULTS A gradual loss of meiotic and post-meiotic germ cells occurred throughout the culture period, irrespective of the presence of gonadotrophins. However, all germ cell types remained traceable for up to 16 days, some still dividing and differentiating at a rate compatible with the in vivo situation. Good maintenance of the general architecture of the explants associated with clearly quantifiable levels of several somatic cell markers was observed. CONCLUSION Although this culture model is clearly unsuitable for preparing germ cells for therapeutic purposes, it does represent a most valuable tool for testing the effects of biological and chemical agents on testicular tissue.

Abstract
Traumatic injuries of the urethra are uncommon. Most Lesions of the anterior (bulbar urethra) are straddle injuries and are initially dealt with by a suprapubic catheter with delayed treatment when urethral stenosis does ensue. Traumatic disruption of the posterior urethra is in most cases related to a pelvic fracture and is often associated with multiple life-threatening injuries, which receive priority treatment. Management of posterior urethral disruption remains a highly controversial issue: alternative treatments include early endoscopic realignment, early open surgical repair and suprapubic catheter and delayed open surgical repair. Management of urethral injuries is described and the different operative techniques are detailed.

Abstract
At the last congress of the American Urological Association (AUA), which took place in San Francisco from the 9th to the 12th May 2004, more than 200 abstracts on prostate cancer were presented as posters or as full communications. We present here the highlights of this congress and in particular the main subjects of news, controversies or innovations. Two major topics are particularly worthy of discussion: localized disease on the one hand and locally advanced or metastatic disease on the other. In the chapter on localized disease, we expound the most relevant data on epidemiology, screening, staging and prognosis. For the locally advanced disease we discuss quality of life, prognostic factors and recent advances in hormone therapy and chemotherapy.

Abstract
OBJECTIVE To develop a model to predict the outcome before surgery for non-metastatic renal cell carcinoma (RCC). PATIENTS AND METHODS The records of 660 patients with non-metastatic RCC, operated at three European medical institutes, were reviewed. Univariate and multivariate analyses were used to assess the clinical and pathological variables affecting disease-free survival. RESULTS The median (range) follow-up was 42 (2-180) months; the disease recurred in 110 patients (16%). The 2- and 5-year overall survival was 87% and 54%, respectively. Five variables were significant in the univariate analysis, i.e. clinical presentation, clinical and pathological size, tumour grade and stage (P < 0.05). The preoperative variables, e.g. clinical presentation and clinical tumour size, were retained from the multivariate model. A recurrence risk formula (RRF) was constructed from this model, as (1.28 x presentation (asymptomatic = 0; symptomatic = 1) + (0.13 x clinical size)). Using this equation, the 2- and 5-year disease-free survival was 96% and 93% for an RRF of < or = 1.2 and 83% and 68% for an RRF of > 1.2. CONCLUSION A formula was developed which, independent of stage, can be used to predict the rate of treatment failure in patients who undergo nephrectomy for non-metastatic RCC. The RRF might be useful for more accurate sub-grouping of good-prognosis patients, and for counselling patients before surgery, their personalized follow-up or adjuvant treatment once available.

Abstract
Hospital acquired infections represent a medical priority for surgeons as well as anesthetists and nursing staff. ANAES charged with national hospital accreditation program establishes protocols and objectives to be attained in terms of quality of care and patient satisfaction. According to available pilot studies, prevention of hospital acquired infections relies on surgical environment, preoperative patient preparation, sterilisation techniques, antibiotic prophylaxis and catheter care. Great improvements are under way in this domain and in management of multiresistant bacterial infections with a decrease in multiresistant kelbsiella infections. Our optimism is however tempered by the increase in methicillino-resistant Staphylococcus aureus (MRSA) infections. Many questions on nosocomial infections are still unanswered due to insufficient scientific evidence and difficulty in organising rigorous studies. Further progress will require a full involvement of hospital administrations and funding health organisations to provide the financial support required to implement preventive procedures and related architectural modifications.

Abstract
INTRODUCTION Spinal cord compression (SCC) in metastatic prostate cancer is not rare occurring in 1 to 12% of patients. We have analysed patients treated for this condition in our institution assessing outcome and prognostic factors. MATERIAL AND METHODS Retrospective analysis of the notes of 24 patients hospitalised with SCC due to metastatic prostate cancer from 1987 to 2001. RESULTS At presentation 3 patients were ambulant with mild neurological deficit, 12 patients were paraparetic and 9 patients were paraplegic. Diagnosis was established by emergency myelogram, CT-scan or MRI of the spine. 8 patients had received no hormone treatment prior to diagnosis of SCC. 19 patients presented dorsal or lumbar pain requiring opioid treatment on average 60 days before onset of neurological symptoms (range 10-840). All patients underwent steroid treatment; the 8 patients without prior hormone therapy were treated with bilateral orchidectomy, 1 out of these 8 patients had castration without other treatments; 12 patients underwent radiotherapy alone and 9 radiotherapy and laminectomy; 2 patients were in terminal conditions and receive only steroid treatment. Overall 15/24 patients were ambulant after treatment. 8 out of 9 patients treated by laminectomy and radiotherapy were ambulant after treatment versus 7 out of 12 patients treated by radiotherapy alone.17 patients died during follow-up with a median survival of 4 months (2 weeks to 49 months). 7 patients were alive at the last control with a mean follow-up of 10 months (range 4-40). CONCLUSION Outlook in patients with spinal cord compression from metastatic prostate cancer is poor. Efforts must be concentrated on prevention of spinal cord compression. Patients with hormone resistant prostate cancer who develop persistent back pain should undergo imaging studies (bone scan, spine CT-scan or MNR) and prophylactic local radiotherapy to the spine if bony metastases are identified.

Abstract
OBJECTIVE To study the incidence, clinical presentation, pathological prognostic factors and disease outcome of RCC in young adults less than 40-years-old. MATERIAL AND METHODS The notes of 400 patients treated by radical nephrectomy for RCC suspicion, between January 1984 and december 1999 were reviewed. Twenty-nine patients (7.25%) were under 40. RESULTS The most common histological cell type was clear cell carcinoma, found in 20 patients (69%). At a median follow-up of 80 months, 20 patients (69%) were disease free and 9 (31%) died of the disease. When comparing patients less than 40 years vs older than 40 years, we found significant differences in histology type (clear cell carcinoma 69% vs 91%; P = 0.0001), and tumor stage at presentation (pT2 = 34.5% vs 17.3%; P = 0.04) (pT3 = 20.7% vs. 42%; P = 0.03). Disease free survival was not significantly different between the 2 groups (69% vs 65.7%; Log rank test P = 0.4). CONCLUSION Although rare, RCC in young adults seems to follow a course similar to the disease seen in older patients. Stage at presentation was different between the 2 populations however survival was not affected by age.

Abstract
The development of cancer on the ileal graft after augmentation ileocystoplasty for benign bladder disease is a little known complication. The authors report a case of squamous cell carcinoma in the ileal bladder occurring 37 years after augmentation ileocystoplasty for tuberculous bladder, in a 68-year old patient. Carcinomatous degeneration is usually occurs more than ten years after cystoplasty. Patients treated by this operation must be submitted to annual cystoscopy combined with guided biopsies at the slightest doubt. This surveillance should be started between the 5th and the 10th postoperative year.

Abstract
OBJECTIVES We determined the incidence and characteristics of adrenal involvement in localized and advanced renal cell carcinoma, and evaluated the role of adrenalectomy as part of radical nephrectomy. PATIENTS AND METHODS From 1993 to 1999, 210 patients with renal cell carcinoma (RCC) (139 men and 71 women, mean age 60.8 years, range 12-96 years) underwent radical nephrectomy with associated adrenalectomy. Patients were divided into two subgroups of 106 with localized (stage T1-2 tumor, group 1) and 104 with advanced (stage T3-4N01M01, group 2) renal cell carcinoma. A retrospective review of preoperative computerized tomography (CT) of the abdomen was performed. Radiographic findings were subsequently compared with postoperative histopathological results to assess the predictive value of tumor characteristics and imaging in determining adrenal metastasis. RESULTS Of the 210 patients, 15 (7.1%) had adrenal involvement. Tumor stage correlated with probability of adrenal spread, with T3-4 and T1-2 accounting for 13.4% and 0.9% of cases, respectively (p < 0.001). Upper pole intrarenal RCC most likely to spread was local extension to the adrenal gland, representing 53.3% of adrenal involvement. In contrast, multifocal, lower pole and mid region RCC tumors metastasized hematogenously, representing 21.4%, 7%, and 14% of adrenal metastasis, respectively. The relationship between intrarenal tumor size (mean 7.8 cm, range 4-21) and adrenal involvement was not statistically significant. Preoperative CT demonstrated 97.7% specificity, 98.4% negative predictive value, 87% sensitivity and 80% positive value for adrenal involvement by RCC. CONCLUSIONS Ipsilateral adrenalectomy should only be performed if a lesion is seen preoperatively on CT scan or if gross disease is seen at the time of nephrectomy. The prognosis is poor for RCC with ipsilateral involvement even with complete removal. Because of this poor prognosis we believe that adrenal involvement should constitute a separate stage category.

Abstract
OBJECTIVE To evaluate the mode of detection of 400 renal tumours as a prognostic factor compared with the usual clinical and pathological prognostic variables. PATIENTS AND METHODS The data were reviewed for 400 patients operated for a renal tumour at our institution between 1984 and 1999, analysing the prognostic value of age, sex, tumour size, stage, grade, vein invasion, adrenal gland invasion, lymph node invasion, metastasis, and mode of detection (incidental or not). The survival rates were assessed using the Kaplan-Meier method and log-rank test, and the data evaluated using multivariate analysis with the Cox proportional-hazard model. RESULTS In all, 151 (38%) renal tumours were discovered incidentally. There was no significant difference in the percentage of renal cell carcinoma found between the groups of patients discovered incidentally or not (94.4% vs 93.9%). Tumours were smaller in the incidental group (5.7 cm vs 8.7 cm, P < 0.001). In the incidental group, 15.2% of the tumours were treated with partial nephrectomy, against 1.2% in the symptomatic group (P < 0.001). The specific survival was significantly better in patients with renal tumours discovered incidentally (log-rank test, P < 0.001). The multivariate analysis showed that the mode of detection, stage, grade, metastasis (all P < 0.001), and lymphatic extension (P = 0.005) were independent prognostic factors. CONCLUSION The incidental discovery of renal tumours gives a supplementary benefit to patients in terms of survival, and should be considered as a prognostic factor in addition to stage and grade.

Abstract
OBJECTIVE To examine whether the outcome of cystectomy for invasive transitional cell carcinoma (TCC) of the bladder was influenced by the type of disease at initial presentation. PATIENTS AND METHODS The charts of 76 patients treated for TCC by radical cystectomy from 1987 to 1997 in our unit were reviewed. The patients were divided into three groups: group 1 comprised 43 patients with primary invasive disease; group 2 included 12 patients with progression of an initial superficial bladder tumour after failure of conservative treatment; and group 3 comprised 21 patients who had a radical cystectomy for superficial TCC, with a high risk of progression after attempts at conservative treatment. The pathological findings on transurethral resection and cystectomy specimens, cancer-specific survival and the time to progression were compared among the three groups. RESULTS The rate of pT0 in cystectomy specimens was 16%, 41% and 24% in groups 1, 2 and 3, respectively. Under-staging occurred in 24% of cases in group 3. The 10-year cancer-specific survival rates were 48%, 47% and 82% in groups 1, 2 and 3, respectively. The cancer-specific survival rate and progression rate were not significantly different between groups 1 and 2, but were significantly lower/higher in these patients than in group 3 (P < 0.01). CONCLUSIONS These data suggest that the prognosis of superficial TCC which progresses despite conservative management is no better than that of invasive TCC at initial presentation, despite the closer follow-up received by the former patients. Early identification of this group of patients may improve the cancer-specific survival, as early cystectomy for high-risk superficial TCC yields better results.

Abstract
Spontaneous perirenal haematomas essentially raise the problem of the aetiological diagnosis, but can sometimes be inadequate. Arteriography is useful when CT scan is negative or in the case of vascular disease. The therapeutic attitude, nephrectomy or conservative treatment remains controversial, but in view of the frequency of renal neoplastic lesions, the authors recommend nephrectomy at the slightest doubt concerning renal integrity. When no case be found, the assessment must be completed postoperatively with long-term, close surveillance, due to the risk of an undiagnosed neoplastic lesion. The authors report two recent cases and try to propose a diagnostic and therapeutic strategy based on the aetiology.

Abstract
PURPOSE Interleukin (IL)-2 and interferon-gamma are released during T helper 1 lymphocyte responses and IL-10 is released during T helper 2 lymphocyte responses. We have previously reported that a T helper 1 lymphocyte urinary cytokine profile is associated with a favorable prognosis after bacillus Calmette-Guerin (BCG) treatment. We evaluated the T helper 1/2 lymphocyte cytokine profiles during courses 1 and 2 of 6 weekly BCG instillations. MATERIALS AND METHODS Urinary interferon-gamma, IL-2 and IL-10 were measured by enzyme-linked immunosorbent assay after each of 6 weekly instillations of 150 mg. BCG, Pasteur strain, in 19 patients with superficial stages Ta and T1 bladder cancer, and carcinoma in situ. The 11 patients who did not respond to course 1 were re-treated according to the same schedule and reevaluated. RESULTS During course 1 interferon-gamma was higher than during course 2 (p <0.001), which was associated with nonrecurrence (p <0.001). In contrast, IL-2 cytokine was higher after course 2 (p <0.01), which was associated with a BCG response (p = 0.01). Interferon-gamma and IL-10 correlated during courses 1 and 2 (p = 0.04 and 0.0004, respectively). We distinguished groups 1-immediate T helper 1 lymphocyte profile consisting of responders to course 1 with high interferon-gamma, IL-2 and IL-10, 2-delayed T helper 1 lymphocyte profile consisting of responders to course 2 with early high IL-2 and 3-consisting of nonresponders to the 2 courses with low interferon-gamma, IL-2 and IL-10. CONCLUSIONS A T helper 1 lymphocyte urinary cytokine profile was associated with a clinical response to BCG. A repeat BCG course induces a favorable immune response in a subset of patients, suggesting that maintenance therapy may be beneficial.

Abstract
BACKGROUND There has been a great deal of discussion regarding the necessity of antibiotic prophylaxis in transurethral cystoscopy. In order to clarify this complicated issue, a randomized prospective study was performed on 126 patients planned for cystoscopy. PATIENTS AND METHODS 126 patients who underwent urethrocystoscopy and did not have pyuria and bacteriuria were included and divided randomly into 2 groups: group 1 received 400 mg of norfloxacine and group 2 nothing. Urinalysis were performed on all patients 3 days after the examination. Statistical analyses were performed using Chi 2 test and the level of significance was set at 5%. RESULTS The global rate of infection was 5%. In the group 1 the incidence of infection was 3% (2/67) vs 5.1% (5/59) in group 2. There were no significant differences in the incidence in the background factor between the 2 groups of patients (p > 0.05). CONCLUSION Prophylactic administration of antibiotic before cystoscopy does not decrease the incidence of urinary tract incidence and it is not necessarily in patients with sterile urine.

Abstract
Renal cell carcinoma (RCC) is known to have a wide variation in clinical outcome despite the use of conventional prognostic factors, such as staging or grading. A better knowledge of the biologic aggressiveness of RCC could facilitate the selection of patients at high risk of tumor progression. The aim of this study was to determine if use of measurements of vascular density, cell proliferation, and cell adhesion could better predict the biologic behavior of RCC. We immunohistochemically analyzed CD34, Ki-67, and CD44H expression on formalin-fixed, paraffin-embedded tissues from 73 RCCs for quantifying microvessel density (MVD), Ki-67 labeling index (LI), and CD44H LI, respectively. Univariate cancer-specific survival analysis showed that tumor stage (P < .01), tumor size (P < .001), nuclear grade (P < .01), metastasis (P < .001), MVD (P < .03), Ki-67 LI (P < .001), and CD44H LI (P < .0001) were predictors of tumor-related death. There was a statistical correlation between CD44H LI and both Ki-67 LI (r' = .3) and MVD (r' = -44). Ki-67 LI (P < .04) and CD44H LI (P < .02), as well as metastasis (P < .008), emerged as independent predictors of cancer-specific survival in multivariate analysis in patients with metastases (P < .04 and P < .02, respectively) and in patients without metastases (P < .006 and P < .00001, respectively). Our study suggests that vascular density, cell proliferation, and cell adhesion represent a complex tumor-host interaction that may favor progression of RCC. Cell proliferation and CD44H expression appear to be powerful markers to identify patients with an adverse prognosis.

Abstract
OBJECTIVE To compare the immunological status of normal and peritumoral bladder walls, and to characterize immunocompetent cells before and during intravesical instillations of bacillus Calmette-Guérin (BCG). PATIENTS AND METHODS Twenty-three patients with superficial urothelial bladder carcinoma (stages pTa to pT1, grades 1-3) were treated with six weekly instillations of 150 mg of BCG (Pasteur strain). Biopsies of cystoscopically normal bladder wall were taken before, 3 weeks and 3 months after BCG instillation. The controls comprised bladder biopsy specimens from 13 brain-dead ventilated kidney donors. Local infiltrating cell types, i.e. lymphocyte infiltrates (CD4, CD8, CD20, CD3, interleukin-2-receptor-positive, natural killer, gammadelta), macrophages and dendritic cells, adhesion and costimulatory molecules (ICAM-1 and B7-BB1) and major histocompatibility complex (MHC) class I and class II antigens were assessed using semi-quantitative immunohistochemical analysis. RESULTS Before BCG the peritumoral bladder wall had fewer macrophages than control bladder wall. BCG treatment restored normal numbers of macrophages and enhanced T helper lymphocytes, B lymphocytes, natural killer cells, activated lymphocytes, dendritic cells, normal MHC class I, adhesion (ICAM-1) and costimulatory (B7-BB1) expression. The enhancement of these immunological variables was transient, with a return to baseline 3 months after BCG instillation. CONCLUSIONS These results support the concept that there is a host-immune escape associated with bladder cancer. BCG therapy may temporarily restore impaired tumour rejection mechanisms in the peritumoral bladder wall, suggesting a need for maintenance therapy after the first course of BCG.

Abstract
OBJECTIVES The aim of the study was to determine whether a nonoperative approach is able to reduce renal parenchymal loss after renal trauma. METHODS Sixty-four consecutive patients with major blunt renal lacerations were treated from 1988 to 1999. Initial management was conservative. In group 1 (35 patients) delayed hemorrhage, persistent urinoma or hemodynamic instability were dealt with by open surgery. In group 2 (29 patients), most complications were dealt with using endoscopic procedures; open surgery was reserved exclusively for major complications. RESULTS In group 1, 7 patients were not operated and 28 patients were managed surgically. Twenty (57%) patients underwent total (8) or partial (12) nephrectomy. In 8 patients the surgical intervention was open drainage of perinephric collection (6) and/or renorrhaphies (2). Four patients in this group developed urinary fistulae treated successfully with ureteral stents. Length of hospital stay was 9.6 days (3-25 days). In group 2, persistent hemodynamic instability led to nephrectomy in 1 case. The remaining 28 patients were managed conservatively, with endoscopic ureteric stenting in 5 cases. A persistent urinary extravasation with hyperthermia led to open drainage of perinephric urinoma (5) and renorrhaphy (2). No delayed nephrectomy was necessary. Average hospital stay was 12 days (5-21 days). Only 1 patient in this group developed hypertension. CONCLUSION For most patients and with close follow-up available, conservative treatment represents a real alternative to open surgery in major blunt renal lacerations. In our experience, open surgery usually results in loss of renal parenchyma.

Abstract
INTRODUCTION Iatrogenic trauma of the ureter can occur following pelvic, abdominal or retroperitoneal surgery and during laparoscopy or ureteroscopy. MATERIAL AND METHODS From 1988 to 1998, 30 patients with 34 iatrogenic ureteric injuries were treated in our department. RESULTS Patients were referred after a mean of 13 days. Endourological treatment was performed as first-line management in 76% of cases of ureteric trauma, with a 71% immediate success rate. In the case of failure, surgery was performed in 78% of cases, with an 83% success rate. Seven patients required nephrectomy and one patient died. CONCLUSION First-line endourological treatment gives good results. An early diagnosis remains an essential prerequisite to avoid serious complications.

Abstract
PURPOSE To evaluate the results of an endoscopic antireflux procedure in women with recurrent acute pyelonephritis and no evidence of vesicoureteral reflux (VUR) on voiding cystograms. PATIENTS AND METHODS From 1989 to 1999, 603 female patients were hospitalized for acute pyelonephritis with unilateral loin pain, chills, fever, and a positive urine culture. Of these patients, 48 (8%) had recurrent episodes of acute pyelonephritis and underwent a thorough diagnostic work-up including intravenous urography or renal CT scan, cystoscopy, and voiding cystourethrography (VCUG). Vesicoureteral reflux was demonstrated in 21 patients, who were then offered an antireflux procedure, either surgical or endoscopic. Another 27 patients had no reflux on VCUG; in 15 cases, the upper urinary tract was normal, and the ureteral orifices did not show any abnormality on cystoscopy. The other 12 patients in this group with a normal VCUG had one or more abnormal findings normally associated with VUR: renal scarring in five and ureteral duplication in two. Golf-hole ureteral orifices were noted in two patients. The intravesical ureter was short (< 5 mm) in five patients. In spite of the normal VCU, we offered these patients endoscopic treatment of VUR by submeatal injection of Teflon or microparticulate silicone (Macroplastic). The median follow-up before treatment was 4 years (range 1-15.3 years); 0.3 episodes of acute pyelonephritis per patient-month of follow-up were noted. The frequence of preoperative and postoperative episodes of acute pyelonephritis was compared with Wilcoxon's paired analysis. The median postoperative follow-up was 3.9 years (range 1.1 months-10.2 years). RESULTS There were no significant postoperative complications. One patient had two episodes of acute pyelonephritis during pregnancy. On the whole, 11 patients (91%) were free of recurrent pyelonephritis after treatment. Overall, 0.003 episodes of acute pyelonephritis per patient-month of postoperative follow-up were observed. The result was statistically significant (P < 0.01). CONCLUSION Recurrent acute pyelonephritis is frequently related to VUR. Intermittent reflux can be difficult to demonstrate on voiding conventional or nuclear cystograms but can be suspected in the presence of ureteral duplication, renal scarring, or abnormal ureteral orifices. Adult patients with recurrent episodes of upper urinary tract infection and normal cystograms should be considered for an endoscopic antireflux procedure in the presence of anatomic abnormalities commonly associated with reflux.

Abstract
PURPOSE We assessed the feasibility, reproducibility and morbidity of retroperitoneal laparoscopic pyeloplasty for ureteropelvic junction obstruction. MATERIALS AND METHODS A total of 55 retroperitoneal laparoscopic pyeloplasties were performed at 3 institutions between September 1996 and May 2000 in 33 women and 21 men. Results were analyzed in regard to radiological assessment by excretory urography at 3 months, complications and hospital stay. RESULTS We performed dismembered pyeloplasty in 48 cases and Fenger plasty in 7 cases. Crossing vessels were noted in 23 patients. The conversion rate was 5.4%. Mean operative time was 185 minutes (range 100 to 260), mean hospital stay was 4.5 days (range 1 to 14) and mean followup was 14.4 months (range 6 to 43.6). The overall complication rate was 12.7%. Complications in 7 patients included hematoma in 3, urinoma in 1, severe pyelonephritis in 1 and anastomotic stricture in 2 requiring open pyeloplasty at 3 weeks and delayed balloon incision at 13 months, respectively. Excretory urography in 50 patients and ultrasound in 4 showed decreased hydronephrosis in 88.9% at 3 months. Normal physical activity and absent pain were reported by 47 patients (87%) 1 month after surgery. CONCLUSIONS Retroperitoneal laparoscopic pyeloplasty seems to be a valuable alternative to open pyeloplasty for ureteropelvic junction obstruction. The long-term outcome must be assessed before this procedure may be definitively validated.

Abstract
OBJECTIVES To study the influence of adverse reactions on adherence to an immunotherapy maintenance schedule and the recurrence rate of bladder cancer. Bacille Calmette-Guérin immunotherapy has documented efficacy in the management of high-risk superficial bladder cancer. However, the optimal duration of intravesical bacille Calmette-Guérin therapy and the risk/benefit ratio of maintenance therapy are controversial. METHODS From April 1996 to April 2000, 72 patients with superficial bladder cancer were treated with Immucyst (six consecutive weekly instillations of 81 mg) and then received maintenance therapy consisting of three consecutive weekly instillations 3, 6, 12, 18, 24, 30, and 36 months later. Adverse reactions, studied during 518 instillations, were classified in four categories using a scale based on the World Health Organization recommendations, and their impact on the adherence to therapy was analyzed. RESULTS After an average follow-up of 24 months, a durable disease-free response was observed in 84.9% of the patients; 12.5% of patients had a relapse and 2.6% had disease progression. The response rate was similar in patients with and without adverse reactions. Only 14 patients (19%) received all the scheduled maintenance instillations. The dose was reduced in 41 patients (57%), and treatment was stopped in 28 patients (39%). In multivariate analysis, an adverse event score of 1.5 or greater during induction therapy was significantly associated with cessation or modification of maintenance therapy (P = 0.01). CONCLUSIONS The scale developed in this study to monitor the adverse reactions to bacille Calmette-Guérin and their impact on the adherence to maintenance therapy may be helpful for tailoring maintenance regimens or implementing protective measures (dose reduction or treatment postponement).

Abstract
OBJECTIVES To examine leukocyturia as a predictor of tumor recurrence and occurrence of adverse events after bacille Calmette-Guérin (BCG) immunotherapy. The use of BCG immunotherapy, a very major advance in the management of superficial bladder cancer, is limited by the frequency of adverse events. As yet, we have no way of predicting the efficacy and tolerability of BCG instillation in clinical practice. This problem is even more acute during BCG maintenance therapy. METHODS Adverse events in 72 patients who received 518 instillations were prospectively assessed using a four-class scale based on severity and duration. Urinary leukocytes were counted 3 days after each instillation, using the KOVA-Slide 10 method. RESULTS High leukocyturia during BCG treatment (cutoff value 1.65 x 10(5)/mL urine) correlated with recurrence-free status (P = 0.009). The degree of leukocyturia correlated with the severity/duration of adverse events (P <0.0001); the median leukocyturia values associated with class I, II, and III adverse events were 4 x 10(4)/mL, 1.5 x 10(5)/mL, and 3.5 x 10(5)/mL, respectively. No class IV events occurred. The cutoff point indicating treatment cessation for adverse events was leukocyturia of 8.6 x 10(4)/mL. CONCLUSIONS These results suggest a link between adverse events and efficacy during BCG maintenance therapy. Leukocyturia appears to correlate with both efficacy and tolerability in this setting. Prospective randomized studies are required to evaluate leukocyturia as a basis on which to adapt the BCG instillation schedule to individual patient susceptibility.
