Three-Dimensional Customized Imaging Reconstruction for Urological Surgery: Diffusion and Role in Real-Life Practice from an International Survey. J Pers Med 2023; 13:1435. [PMID: 37888045 PMCID: PMC10607910 DOI: 10.3390/jpm13101435] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 09/21/2023] [Accepted: 09/22/2023] [Indexed: 10/28/2023] Open
Abstract
Despite the arising interest in three-dimensional (3D) reconstruction models from 2D imaging, their diffusion and perception among urologists have been scarcely explored. The aim of the study is to report the results of an international survey investigating the use of such tools among urologists of different backgrounds and origins. Beyond demographics, the survey explored the degree to which 3D models are perceived to improve surgical outcomes, the procedures mostly making use of them, the settings in which those tools are mostly applied, the surgical steps benefiting from 3D reconstructions and future perspectives of improvement. One hundred responders fully completed the survey. All levels of expertise were allowed; more than half (53%) were first surgeons, and 59% had already completed their training. Their main application was partial nephrectomy (85%), followed by radical nephrectomy and radical prostatectomy. Three-dimensional models are mostly used for preoperative planning (75%), intraoperative consultation and tailoring. More than half recognized that 3D models may highly improve surgical outcomes. Despite their recognized usefulness, 77% of responders use 3D models in less than 25% of their major operations due to costs or the extra time taken to perform the reconstruction. Technical improvements and a higher availability of the 3D models will further increase their role in surgical and clinical daily practice.

The Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration Project: Development of Criteria for Reporting Adverse Events During Surgical Procedures and Evaluating Their Impact on the Postoperative Course. Eur Urol Focus 2022; 8:1847-1858. [PMID: 35177353 DOI: 10.1016/j.euf.2022.01.018] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 12/22/2021] [Accepted: 01/28/2022] [Indexed: 12/16/2022]
Abstract
BACKGROUND Intraoperative adverse events (iAEs) are surgical and anesthesiologic complications. Despite the availability of grading criteria, iAEs are infrequently reported in the surgical literature and in cases for which iAEs are reported, these events are described with significant heterogeneity. OBJECTIVE To develop Intraoperative Complications Assessment and Reporting with Universal Standards (ICARUS) Global Surgical Collaboration criteria to standardize the assessment, reporting, and grading of iAEs. The ultimate aim is to improve our understanding of the nature and frequency of iAEs and our ability to counsel patients regarding surgical procedures. DESIGN, SETTING, AND PARTICIPANTS The present study involved the following steps: (1) collecting criteria for assessing, reporting, and grading of iAEs via a comprehensive umbrella review; (2) collecting additional criteria via a survey of a panel of experienced surgeons (first round of a modified Delphi survey); (3) creating a comprehensive list of reporting criteria; (4) combining criteria acquired in the first two steps; and (5) establishing a consensus on clinical and quality assessment utility as determined in the second round of the Delphi survey. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Panel inter-rater agreement and consistency were assessed as the overall percentage agreement and Cronbach's α. RESULTS AND LIMITATIONS The umbrella review led to nine common criteria for assessing, grading, and reporting iAEs, and review of iAE grading systems led to two additional criteria. In the first Delphi round, 35 surgeons responded and two criteria were added. In the second Delphi round, 13 common criteria met the threshold for final guideline inclusion. All 13 criteria achieved the consensus minimum of 70%, with agreement on the usefulness of the criteria for clinical and quality improvement ranging from 74% to 100%. The mean inter-rater agreement was 89.0% for clinical improvement and 88.6% for quality improvement. CONCLUSIONS The ICARUS Global Collaboration criteria might aid in identifying important criteria when reporting iAEs, which will support all those involved in patient care and scientific publishing. PATIENT SUMMARY We consulted a panel of experienced surgeons to develop a set of guidelines for academic surgeons to follow when publishing surgical studies. The surgeon panel proposed a list of 13 criteria that may improve global understanding of complications during specific procedures and thus improve the ability to counsel patients on surgical risk.

Correlation Between Long-Term Acetylsalicylic Acid Use and Prostate Cancer Screening with PSA. Should We Reduce the PSA Cut-off for Patients in Chronic Therapy? A Multicenter Study. Res Rep Urol 2022; 14:369-377. [PMID: 36304173 PMCID: PMC9595058 DOI: 10.2147/rru.s377510] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 10/14/2022] [Indexed: 11/06/2022] Open
Abstract
Purpose To evaluate the prostate cancer (PCa) detection rate in men with chronic use of Aspirin and to compare it with the detection rate of non-users. Patients and Methods Prospectively maintained database regarding patients undergoing prostate biopsy over the last 10 years in five institutions. Patients were divided into two groups according to their exposure to Aspirin. We relied on multivariable linear and logistic regression models to test whether Aspirin administration was associated with lower PSA values at prostate biopsy, higher PCa diagnosis, and higher Gleason Grade Grouping (GGG) at biopsy. Results Were identified 1059 patients, of whom 803 (76%) did not take Aspirin vs 256 (24%) were taking it. In multivariable log-linear regression analysis, Aspirin administration was associated with lower PSA levels (OR 0.83, 95% CI 0.71–0.97, p = 0.01), after controlling for age, prostate volume, smoking history, associated inflammation at prostate biopsy, presence of PCa at biopsy, and GGG. In multivariable logistic regression analysis, Aspirin administration was not found to be a predictor of PCa at prostate biopsy (OR 1.40, 95% CI 0.82–2.40, p = 0.21) after controlling for age, PSA, smoking history, prostate volume, findings at digital rectal examination and the number of biopsy cores. In patients with PCa at prostate biopsy (n = 516), Aspirin administration was found to predict higher GGG (OR 2.24, 95% CI 1.01–4.87, p = 0.04). Conclusion Aspirin administration was found to be a predictor of more aggressive GGG. These findings suggest that a lower PSA threshold should be considered in patients taking Aspirin, as, despite low PSA levels, they might harbour aggressive PCa.

Perioperative outcomes of patients undergoing urological elective surgery during the COVID-19 pandemic: a national overview across 28 Italian institutions. Cent European J Urol 2021; 74:259-268. [PMID: 34336248 PMCID: PMC8318031 DOI: 10.5173/ceju.2021.0374] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 03/02/2021] [Accepted: 04/08/2021] [Indexed: 12/11/2022] Open
Abstract
Introduction The aim of this study was to assess the safety of elective urological surgery performed during the pandemic by estimating the prevalence of COVID-19-like symptoms in the postoperative period and its correlation with perioperative and clinical factors. Material and methods In this multicenter, observational study we recorded clinical, surgical and postoperative data of consecutive patients undergoing elective urological surgery in 28 different institutions across Italy during initial stage of the COVID-19 pandemic (between February 24 and March 30, 2020, inclusive). Results A total of 1943 patients were enrolled. In 12%, 7.1%, 21.3%, 56.7% and 2.6% of cases an open, laparoscopic, robotic, endoscopic or percutaneous surgical approach was performed, respectively. Overall, 166 (8.5%) postoperative complications were registered, 77 (3.9%) surgical and 89 (4.6%) medical. Twenty-eight (1.4%) patients were readmitted to hospital after discharge and 13 (0.7%) died. In the 30 days following discharge, fever and respiratory symptoms were recorded in 101 (5.2%) and 60 (3.1%) patients. At multivariable analysis, not performing nasopharyngeal swab at hospital admission (HR 2.3; CI 95% 1.01–5.19; p = 0.04) was independently associated with risk of developing postoperative medical complications. Number of patients in the facility was confirmed as an independent predictor of experiencing postoperative respiratory symptoms (p = 0.047, HR:1.12; CI95% 1.00–1.05), while COVID-19-free type of hospitalization facility was a strong independent protective factor (p = 0.02, HR:0.23, CI95% 0.07–0.79). Conclusions Performing elective surgery during the COVID-19 pandemic does not seem to affect perioperative outcomes as long as proper preventive measures are adopted, including nasopharyngeal swab before hospital admission and hospitalization in dedicated COVID-19-free facilities.

Abstract
Histiocytic sarcoma (HS) is a rare malignant lymphohematopoietic neoplasm; it has been cited in the recent World Health Organization (WHO) classification as a malignant proliferation of cells exhibiting morphological and immunophenotypic features of mature histiocytes. To our knowledge, the present case is the first to be described in the bladder of a patient without a history of lymphoma. Only one case has been reported so far regarding a secondary bladder presentation in the setting of a previous diffuse large B-cell lymphoma. We discuss the case of a 68-year-old male who presented with hematuria and dysuria. CT scan revealed a 4-cm intravesical mass that histological examination defined as HS. Our objective was to describe the clinical, histological, immunophenotypical, molecular characteristics and discuss the differential diagnoses of this first case of primary bladder HS. Our research was based on a review of selected articles obtained via the PubMed database. This extremely rare experience provided us with the opportunity to depict an interesting case, highlight its uniqueness, and build up new pathological evidence.

Abstract
Objective To describe the trend in surgical volume in urology in Italy during the coronavirus disease 2019 (COVID‐19) outbreak, as a result of the abrupt reorganisation of the Italian national health system to augment care provision to symptomatic patients with COVID‐19. Methods A total of 33 urological units with physicians affiliated to the AGILE consortium (Italian Group for Advanced Laparo‐Endoscopic Surgery; www.agilegroup.it) were surveyed. Urologists were asked to report the amount of surgical elective procedures week‐by‐week, from the beginning of the emergency to the following month. Results The 33 hospitals involved in the study account overall for 22 945 beds and are distributed in 13/20 Italian regions. Before the outbreak, the involved urology units performed overall 1213 procedures/week, half of which were oncological. A month later, the number of surgeries had declined by 78%. Lombardy, the first region with positive COVID‐19 cases, experienced a 94% reduction. The decrease in oncological and non‐oncological surgical activity was 35.9% and 89%, respectively. The trend of the decline showed a delay of roughly 2 weeks for the other regions. Conclusion Italy, a country with a high fatality rate from COVID‐19, experienced a sudden decline in surgical activity. This decline was inversely related to the increase in COVID‐19 care, with potential harm particularly in the oncological field. The Italian experience may be helpful for future surgical pre‐planning in other countries not so drastically affected by the disease to date.

Abstract
Background The aim of this work is to evaluate the detection rate of magnetic resonance imaging/transrectal ultrasound (MRI/TRUS) fusion-guided biopsy for clinically significant prostate cancers (Cs PCas), with particular interest in biopsy-naive patients and patients in active surveillance. MRI-targeted biopsy improves cancer detection rate (DR) in patients with prior negative biopsies; the current literature focuses on biopsy naive patients. We also evaluated the pathologic concordance between biopsies and surgical specimens. Methods MRI/TRUS fusion-guided biopsies were performed between February 2016 and February 2019. Patients with previous negative biopsies, biopsy-naive or in active surveillance (AS) were included. Cs PCas were defined through Epstein's criteria. Results A total of 416 men were enrolled. The overall DRs and Cs PCa DRs were 49% and 34.3%, respectively. Cs PCas were 17.2%, 44.9% and 73.4%, respectively for PI-RADS 3, 4 or 5. Among biopsy-naive patients, 34.8% were found to have a Cs PCa, while a 43.6% tumour upgrading was achieved in men with a low risk of PCa. In patients who underwent radical prostatectomy (RP), the concordance between biopsy Gleason score (GS) (bGS) and pathological GS (pGS) was 90.8%. Conclusion Our study highlights the role of MRI/TRUS fusion prostate biopsy in the detection of PCa in patients with previous negative biopsies focusing on Cs PCa diagnosis. The MRI/TRUS fusion biopsy is also emerging as a diagnostic tool in biopsy-naïve patients and deserves a fundamental role in AS protocols. A greater concordance between bGS and pGS can be achieved with targeted biopsies.

Abstract
PURPOSE The coronavirus disease 2019 (COVID-19) pandemic has put a substantial burden on the Italian healthcare system, resulting in the restructuring of hospitals to care for COVID-19 patients. However, this has likely impacted access to care for patients experiencing other conditions. We aimed to quantify the impact of COVID-19 on access to care for patients with urgent/emergent urological conditions throughout Italy. MATERIALS AND METHODS A questionnaire was sent to 33 urological units in the AGILE consortium, asking clinicians to report on the number of urgent/emergent urological patients seen and/or undergoing surgery over a 3-week period during the peak of the COVID-19 outbreak and a reference week prior to the outbreak. ANOVA and linear regression models were used to quantify these changes. RESULTS Data from 27 urological centres in Italy showed a decrease from 956 patients/week seen just prior to the outbreak to 291 patients/week seen by the end of the study period. There was a difference in the number of patients with urgent/emergent urological disease seen within/during the different weeks (all p values < 0.05). A significant decrease in the number of patients presenting with haematuria, urinary retention, urinary tract infection, scrotal pain, renal colic, or trauma and urgent/emergent cases that required surgery was reported (all p values < 0.05). CONCLUSION In Italy, during the COVID-19 outbreak there has been a decrease in patients seeking help for urgent/emergent urological conditions. Restructuring of hospitals and clinics is mandatory to cope with the COVID-19 pandemic; however, the healthcare system should continue to provide adequate levels of care also to patients with other conditions.

Abstract
INTRODUCTION T1 bladder cancer is associated with a high risk of recurrence and progression; concomitant carcinoma in situ and/or multifocality are negative prognostic factors. Persistent disease after resection of T1 tumours has been observed in 33-55% of patients, and after resection of High-grade (HG) Ta tumour in 41,4%. It has been demonstrated that a second TURB can increase recurrence-free survival and it can make a restaging of the cancer. PATIENTS AND METHODS From January 2011 to December 2016, 87 patients with superficial bladder tumor (Ta-T1), undergoing TURB and routine repeat TURB (Re-TURB) 4-6 weeks after the initial resection, were included in the study. Re-TURB was applied to the scar of the first resection and other suspicious lesions in the bladder. After the second-look, we studied the follow-up of each patient. RESULTS Specimens obtained during the second TURBT showed no tumor in 47 (54,02%) patients; 40 (45,98%) patients had residual cancer: 34 of them had cancer of the same stage, 6 patients of pT1 had a lower stage, and 3 had a higher stage. 5 patient underwent radical cistectomy immediatly after re-TURBT. During the first year of follow up, 15 patients had a recurrent bladder cancer; 2 of them underwent radical cistectomy. CONCLUSIONS T1 bladder cancer is an high risk tumor, so that second-look TURBT is a valuable procedure for accurate staging of nonmuscle-invasive bladder cancer and it can guarantee a better eradication of the neoplasm.

Abstract
INTRODUCTION Bladder mucosa is anatomically covered by urothelial epithelium. The replacement of the urothelium with stratified squamous cells is defined as squamous metaplasia which can be keratinizing or non-keratinizing. Clinically, it is also known as leukoplakia or keratinizing cystitis of the bladder. Although several etiologic factors have been proposed such as chronic inflammation, irritative stimuli and infection, its pathogenesis is not clearly understood. The natural history of squamous metaplasia and clinical treatment are controversial. Many authors consider squamous metaplasia as a premalignant lesion, so it is fundamental to find an effective treatment to reduce the risk of developing bladder squamous carcinoma. CASE DESCRIPTION We report our management of a 58-year-old man with histological evidence of keratinizing squamous metaplasia and severe lower urinary tract symptoms. After repeated transurethral resections, the patient was treated with intravesical instillation of hyaluronic acid showing the regression of the lesion with an improvement of macroscopic appearance followed by the resolution of clinical symptoms. CONCLUSION The therapeutic management of keratinizing squamous metaplasia is controversial, and currently no effective medical therapy is available for its treatment. Actually, patients undergo transurethral resections and a multidisciplinary approach is required to avoid cystectomy. Annual cystoscopy with multiple biopsies should be performed to determine the presence of dysplasia. Moreover, the therapeutic treatment with hyaluronic acid instillations could be the starting point and the gold standard in the follow-up of our patient. However, at present, further studies are required to formulate an adequate policy for therapeutic management of this unusual lesion of the bladder mucosa.

Abstract
Background: Chronic prostatitis/chronic pelvic pain syndrome (IIIB CP/CPPS) is a condition of unclear aetiology. Many approaches have been used without satisfactory results. The aim of this study is to evaluate the efficacy of once-daily 5 mg tadalafil in pain control and improving quality of life in patients affected by CP/CPPS. Methods: Twenty patients affected by chronic prostatitis according EAU (European Association of Urology) guidelines were evaluated for once-daily 5 mg tadalafil; 14 patients were eligible for the study. The validated Italian version of the NIH Chronic Prostatitis Symptom Index (NIH-CPSI) and the International Prostatic Symptom Score (IPSS) questionnaires were submitted to all the patients. Every patient underwent uroflowmetry and ultrasound prostatic volume at the beginning and at the end of the study. Results: All 14 patients eligible for the study reported an improvement of symptoms during therapy: statistically significant differences were reported in terms of NIH-CPSI (p < 0.000002) and IPSS (p < 0.0001) during follow-up evaluations. No statistically significant improvement of uroflowmetry parameters was reported during the treatment. Conclusions: In our study the daily use of 5 mg tadalafil improves symptoms and quality of life in patients affected by CP/CPPS after 4 weeks of therapy. A larger population of patients is needed to confirm the efficacy of this therapy in CP/CPPS.

Abstract
CONTEXT Postoperative acute kidney injury (AKI) is a serious complication after kidney surgery, associated with prolonged hospital stay, high morbidity, and mortality. Biomarkers represent a tool of increasing importance to identify renal impairment after partial nephrectomy (PN) or radical nephrectomy (RN) in order to optimize and anticipate the diagnosis of AKI. OBJECTIVE The goal of this systematic review is to investigate current insights on the role of biomarkers in predicting renal impairment in patients undergoing PN or RN. EVIDENCE ACQUISITION A systematic review was conducted up to November 30, 2017 through PubMed, Scopus, and Embase databases, to identify eligible studies evaluating the role of biomarkers for the prediction of AKI after PN or RN. The Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) criteria were applied to select articles. EVIDENCE SYNTHESIS According to the study selection criteria, 10 publications were included with a total number of 728 patients. Incidence of AKI was 26.7% (range: 9-58%). Based on the evidence reviewed, serum cystatin C and urinary neutrophil gelatinase-associated lipocalin (NGAL) showed a significant correlation with serum creatinine rise postoperatively, emerging as potential noninvasive and early biomarkers of AKI in patients undergoing renal surgery. In this setting, serum cystatin C and urinary NGAL have preceded the rise in serum creatinine peak from 3 up to 24h, even in case of mild renal damage. CONCLUSIONS The literature underlines the potential usefulness of biomarkers such as cystatin C and NGAL as promising and early tools to predict AKI after PN or RN. However, no strong evidence in support of their use is available to date and further investigations are awaited. PATIENT SUMMARY We looked at the role of biomarkers in predicting renal injury in patients undergoing partial or radical nephrectomy. Serum cystatin C and urinary neutrophil gelatinase-associated lipocalin have emerged as promising noninvasive, accurate, and early biomarkers.

Abstract
Objective: Three-dimensional (3D) laparoscopy was developed to overcome the main limitations of traditional laparoscopy. The aim of our study was to compare operative, functional and oncological results of 3D and two-dimensional (2D) laparoscopic radical prostatectomy. Materials and methods: A total of 102 consecutive patients with clinically localised prostate cancer underwent laparoscopic radical prostatectomy. Patients were randomly assigned into two groups, 2D high definition (HD) camera (50 patients) for the first and 3D HD camera (52 patients) for the second group. Total operative time, anastomosis time, blood loss, complications and pentafecta rates for both groups were compared. All patients had at least one year of follow-up. Results: Total operative time was, respectively, 143 ± 17 and 118 ± 15 minutes, with a mean anastomosis time of 31± 12 and 23 ± 12 minutes. Mean blood loss was 230 ± 30 ml with 2D vision and 175 ± 40 with 3D vision. Pentafecta was reached, respectively, by 46% and 50% of patients at 3 months and 60% and 67.3% at 12 months. 3D vision offers an increased speed if compared with traditional vision ( P=0.02). Pentafecta results were significantly better in the 3D group ( P=0.03). Conclusion: We believe that 3D laparoscopy offers important advantages for surgeons and patients; its use should be encouraged. Level of evidence: 1c

Abstract
INTRODUCTION In Western countries about 25% of prostate cancer (PCa) are high-risk tumors at presentation and its treatment is still a matter of debate among urologists. When a surgical approach is preferred the use of a mininvasive tecnique is still difficult due to the lack of data supporting it in literature. The aim of this study is to evaluate feasibility and safety of laparoscopic radical prostatectomy (LRP) for high-risk PCa. MATERIALS AND METHODS The study included 1114 patients with high-risk PCa submitted to LRP between 1998 and 2014. High-risk patients were defined according to D'Amico classification. We collected functional and oncological long-term outcomes and evaluated with univariate and multivariate analyses the role of predictive factors for survival and biochemical recurrence (BR). RESULTS Mean age at treatment was 62 ± 8 years; mean follow-up was 74 ± 50 months. We obtained an overall survival (OS) of 96.6% at a mean follow-up of 74 months (1076 patients) and a disease-free survival of 66.2% (737 patients). Age (p = 0.0006), pT (p < 0.0001), pN (p = 0.0018), and surgical margins (p = 0.0076) resulted as independent predictors for BR in multivariate analysis. pN (p = 0.0025) and Gs (p = 0.0003) are independent predictors for OS and cancer-specific survival in a univariate analysis; just the Gs results significant in the multivariate model. CONCLUSIONS According to our encouraging data about oncological and functional outcomes we believe that radical prostatectomy represents an effective treatment for patients with high-risk PCa and that laparoscopy is a safe approach offering a mini-invasive alternative to open surgery.

Abstract
PURPOSE The completion of the vescico-urethral anastomosis (VUA) represents the most critical step of laparoscopic radical prostatectomy (LRP), and it can often discourage the use of minimally invasive surgery in less experienced laparoscopic surgeons. The aim of this paper is to evaluate the usefulness of a new robotic needle driver named Dextérité in performing the VUA after LRP. MATERIALS AND METHODS This prospective randomized clinical study enrolled 40 consecutive patients eligible for LRP, which were randomized into four groups: group A, patients undergoing LRP done by an expert surgeon; group B, patients undergoing robotic-assisted radical prostatectomy (RARP) performed by the same expert surgeon; group C, patients undergoing LRP performed by a young surgeon at the beginning of the learning curve; group D, patients undergoing LRP performed by another young surgeon at the beginning of the learning curve with the aid of Dextérité needle driver for completion of the VUA. The two young urologists performed the same steps of LRP so that they are at the same step of the learning curve. All the anastomosis were performed with the same technique in order to be comparable. We use interrupted sutures with Vicryl 2/0 and a 5/8 needle; we performed the Rocco stitch technique before all the anastomosis (6) and we applied bladder neck sparing technique. All patients underwent an ultrasound control of the anastomosis on the seventh postoperative day, as we usually do (9, 10). We consider continent who utilised no pad. RESULTS Operative VUA completion time was 24.9 vs. 25 vs. 86.7 vs. 61 minutes, respectively. When comparing VUA completion time in group 3 and 4, the use of the Dextérité needle driver resulted in a reduction in VUA time. Urinary leakage was seen in zero out of 10 patients in groups 1 and 2 and in three out of 10 and one in 10 patients, respectively, in groups 3 and 4. All urinary leakages were managed conservatively. One-year continence rates were 95%, 97%, 93% and 95%, respectively. Only one patient in group C developed a bladder neck contracture 6 months after the procedure, but he underwent adiuvant radiotherapy after surgery. CONCLUSIONS Our data suggest that the use of Dextérité needle holder significantly reduces operative time of VUA completion and reduces the incidence of urinary leakage in laparoscopic surgeons at the beginning of the learning curve.

The morbidity of laparoscopic radical cystectomy: analysis of postoperative complications in a multicenter cohort by the European Association of Urology (EAU)-Section of Uro-Technology. World J Urol 2015; 34:149-56.

Abstract
PURPOSE To analyze postoperative complications after laparoscopic radical cystectomy (LRC) and evaluate its risk factors in a large prospective cohort built by the ESUT across European centers involved in minimally invasive urology in the last decade. METHODS Patients were prospectively enrolled, and data were retrospectively analyzed. Only oncologic cases were included. There were no formal contraindications for LRC: Also patients with locally advanced tumors (pT4a), serious comorbidities, and previous major abdominal surgery were enrolled. All procedures were performed via a standard laparoscopic approach, with no robotic assistance. Early and late postoperative complications were graded according to the modified Clavien-Dindo classification. Multivariate logistic regression was performed to explore possible risk factors for developing complications. RESULTS A total of 548 patients were available for final analysis, of which 258 (47%) experienced early complications during the first 90 days after LRC. Infectious, gastrointestinal, and genitourinary were, respectively, the most frequent systems involved. Postoperative ileus occurred in 51/548 (9.3%) patients. A total of 65/548 (12%) patients underwent surgical re-operation, and 10/548 (2%) patients died in the early postoperative period. Increased BMI (p = 0.024), blood loss (p = 0.021), and neoadjuvant treatment (p = 0.016) were significantly associated with a greater overall risk of experiencing complications on multivariate logistic regression. Long-term complications were documented in 64/548 (12%), and involved mainly stenosis of the uretero-ileal anastomosis or incisional hernias. CONCLUSIONS In this multicenter, prospective, large database, LRC appears to be a safe but morbid procedure. Standardized complication reporting should be encouraged to evaluate objectively a surgical procedure and permit comparison across studies.

Multidetector CT imaging of complications after laparoscopic nephron-sparing surgery. Insights Imaging 2015; 6:465-78. [PMID: 26104123 PMCID: PMC4519814 DOI: 10.1007/s13244-015-0413-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2015] [Revised: 05/18/2015] [Accepted: 05/21/2015] [Indexed: 11/29/2022] Open
Abstract
Purpose Laparoscopic nephron-sparing surgery (L-NSS) is increasingly performed to treat localised renal lesions. However, the associated morbidity is non-negligible, with a rate of major complications approaching 10 %. Methods and Results This paper provides an overview of indications, surgical techniques and results of L-NSS; explains the incidence, risk factors and manifestations of postoperative complications; discusses the preferred multidetector computed tomography (CT) acquisition techniques; illustrates the appearance of normal postoperative images following L-NSS; and reviews, with example images, the most common and unusual iatrogenic complications. These include haematuria, haemorrhage, vascular injuries, infections and urinary leaks. Most emphasis is placed on CT, which provides rapid, reliable triage and follow-up of iatrogenic complications after L-NSS, identifying occurrences that require transarterial embolisation or repeated surgery. Conclusions Multidetector CT allows precise assessment of the surgical resection site; detection of pneumoperitoneum and subcutaneous emphysema; quantification of retroperitoneal blood; and identification of active bleeding, pseudoaneurysms, arterio-venous fistulas, abscess collections and extravasated urine. Teaching Points • Laparoscopic nephron-sparing surgery (NSS) is increasingly performed to treat renal lesions. • Radiologists are increasingly requested to investigate suspected post-surgical NSS complications. • Post-NSS complications include haemorrhage, haematuria, vascular injuries, infections and urinary leaks. • Multidetector CT allows choice between conservative treatment, transarterial embolisation or surgery.

Abstract
OBJECTIVE To analyze positive surgical margins (PSM) after radical prostatectomy (RP) in the overall population and in patients previously treated with transurethral resection of the prostate (TURP). MATERIALS AND METHODS 2,408 patients treated with RP for clinically localized prostate cancer (PCa) were consecutively enrolled in 135 departments. We correlated PSM rates and all preoperative, surgical and pathological features. We stratified the site of PSM as unique or multifocal. Moreover, we analyzed differences between 75 patients who had undergone previous TURP and the remaining 2,333 patients. RESULTS In the entire study population, we identified 702 patients with PSM (29%). Using univariate analysis, we reported a significant correlation between overall PSM and prostate-specific antigen (PSA), stage cT, biopsy Gleason score, number of biopsy cores, number of positive cores, percentage of positive cores and nerve-sparing approach. PSM proved to be strongly dependent on pT in particular in patients with pT2 PCa. When we compared the data from 75 patients previously treated with TURP and those from 2,333 without previous prostatic surgery, a statistically significant difference in margin localization was found. Moreover, we analyzed the 75 patients mentioned above, stratified in incidental PCa diagnosed at TURP or PCa detected with prostate biopsy for PSA rising during the post-TURP follow-up: no statistical differences were found between the 2 groups regarding margin status, even if PSM were more frequent in incidental PCa with no significance deriving from the stratification for PSM location at the apex or base. CONCLUSION Men treated with TURP before RP presented an overall incidence of PSM similar to those without previous TURP, but with a higher risk of PSM at the bladder neck and a lower risk of PSM at the prostatic apex.

Abstract
Purpose Women undergoing radical cystectomy (RC) and urinary diversion for bladder cancer experience substantial limitations in health-related quality of life (HRQOL). However, the level of discomfort caused by different urinary diversion has been never evaluated in long term survivors. The aim of this multicenter study is to evaluate differences in HRQOL among recurrence-free women undergoing cutaneous ureterostomy (CUS), Bricker's ileal conduit (BK-IC) and Orthotopic neobladder VIP (ONB-VIP) in disease-free females treated with radical cystectomy (RC), with long-term follow up (mean 60.1 months; range 36-122 months). Materials and methods All consecutively treated female patients from two urological institutions who underwent RC and urinary diversion from January 2000 to December 2008, with no evidence of tumor recurrence at a minimum follow up of 36 months, were included. Patients received the European Organisation for Research and Treatment of Cancer (EORTC) generic (QLQ-C30) and bladder cancer-specific instruments (QLQ-BLM30) and the Functional Assessment of Cancer Therapy for Bladder Cancer (FACT-BL). Clinical data and questionnaire results were analyzed in order to evaluate the HRQOL differences among diversion groups. Results We identified 37 females (median age: 68, range 45–82 years), including 12 status-post CUS, 16 who underwent BK-IC, and 9 who underwent ONB-VIP. Most were healthy (24/37 with no comorbidities, 4/37 Charlson 1-2, 9/37 Charlson 3 or greater – we didn’t considered bladder cancer in Charlson evaluation because bladder cancer was the main inclusion criteria). Women undergoing CUS endorsed worse FACT-BL scores compared with BK-IC and ONB-VIP patients, worse HRQOL regarding physical and emotional well-being (p=0.008 and p=0.02, respectively), and a trend toward worse EORTC QLQ-C30 scores for appetite loss and fatigue (p=0.05 for both). Conclusions In our study long-term disease-free females treated with CUS endorsed worse HRQOL compared with women who underwent BK-IC or ONB-VIP, mostly due to worse physical and emotional perception of their body image.

Abstract
OBJECTIVE To retrospectively evaluate the clinical outcomes of 20 patients diagnosed with a nonpalpable or small testicular mass (2 cm) at 2 academic urological department. Testis-sparing surgery (TSS) is currently performed routinely for the management of nonpalpable testicular masses. High reliability of frozen section examination (FSE) and high-frequency ultrasound (US) and the adoption of microsurgical techniques improved safety and feasibility of this technique. METHODS From January 2004 to March 2011, 23 patients underwent microsurgical TSS. An inguinal approach was performed in 22 cases and a suprapubic incision in one bilateral case. All procedures were performed with an operating microscope, with warm ischemia in 21 cases and cold ischemia in 2 cases. Intraoperative US was performed before opening the albuginea. Mean operative time was 89 minutes. RESULTS After mass excision, FSE was performed; only 2 seminomatous tumors were identified, and the remaining masses were benign lesions. After a mean follow-up >12 months, all patients are free of disease; no hypogonadism developed. CONCLUSIONS TSS performed using an operating microscope allowed the preservation of testes for 21 patients diagnosed with small testicular and/or nonpalpable mass (<2 cm), without evidence of disease recurrence or de novo onset. This approach could be mandatory in the treatment of bilateral tumors or in solitary testis. Maintaining fertility is not the main goal of TSS because a great number of patients affected by testicular tumors are already infertile. Esthetic outcomes and sparing hormonal function are the main reasons for TSS.

Abstract
Objective. A number of evidence-based guidelines for diagnosis and management of prostate cancer have been published. The aim of this study is to evaluate the adherence of Italian urologists to the guidelines concerning the preoperative imaging staging of prostate cancer. Methods. In October 2007 a multicentric observational perspective study called Multicentric Italian Report on Radical prostatectomy Outcome and Research (MIRROR) was started in 135 Italian urology centers. Recruitment was closed in December 2008 and 2,408 cases were collected. In this paper we have taken into consideration all examinations carried out for preoperative imaging staging, evaluating compliance with the recommendations in the American Urological Association (AUA) and European Association of Urology (EAU) guidelines. Results. Five hundred sixty-seven (53.34%) patients were not managed according to the EAU guidelines concerning T-staging, 545 (51.27%) concerning N-staging and 757 (71.21%) concerning M-staging. According to AUA guidelines, we also analyzed patients with a Gleason grade of biopsy specimens of 7: 238 (57.35%) of these patients had undergone testing for T staging, 244 (57.35%) for N-staging and 322 (77.60%) for M-staging. Conclusions. The compliance of Italian urologists with the guidelines is low, leading to an inappropriate increase in cost of care and unnecessary anxiety for the patients.

Abstract
OBJECTIVES Bladder outlet obstruction with obstructive and irritative urinary symptoms may be a complication of surgery for female urinary incontinence. In presence of persistent symptoms the therapy is surgical and usually consists in an accurate urethrolysis. The way of approach is generally transvaginal. In this paper we propose and describe our experience with a transvestibular approach. METHODS From 1995 to 2009 18 women who had undergone anti-incontinence surgery (TVT 12 pts, TOT 3 pts, Burch retropubic colposuspension 3 pts) with obstruction and/or irritative symptoms underwent to a transvestibular urethrolysys. Five patients had urinary retention the other patients had post voiding residual urine > 100 ml. With a scalpel blade a circum-meatal incision was performed and the urethra was progressively freed, dissecting just below the os pubis upwards and on the vaginal wall downwards untethering it under direct vision obtaining a complete circular freeing of the urethra; at the end the urethral meatus is repositioned with circular stiches. RESULTS The operation lasts between 20 and 40 minutes. Urethral catheter was left in place for 24-48 hours and no complications were observed. The post-voiding residual urine decreased in all the cases and the irritative symptoms were reduced. CONCLUSIONS The transvestibular approach represents a safe and effective approach to urethrolysis undependently of the type of anti-incontinence surgey carried out. Urethrolysis has the advantage of working in a relatively unscarred tissue, can allow a complete untethering of the urethra even in the retropubic space and leaves the vaginal wall intact.

Abstract
PURPOSE As in men, female urethral stricture disease is often treated with repeat urethral dilation or internal urethrotomy but not always with good results. In nonresponsive cases surgical treatment may be useful but only a few cases are reported in the literature. We present our single institution experience with urethral reconstruction in 6 patients using an alternative vaginal inlay flap technique inspired by the Orandi technique. MATERIALS AND METHODS We treated 6 women with urethral stricture. In 5 patients stricture involved the entire middle and distal urethra, and in 1 it also involved the proximal urethra with bilateral hydronephrosis. Patients underwent urethral reconstruction using a vaginal flap with a lateral vascular pedicle that maintains the vascular axis. The flap was partially de-epithelialized to favor tissue cicatrix formation where the sutures are placed and avoid fistula formation. RESULTS Mean followup was 70.8 months. Normal micturition was achieved after catheter removal in all patients. Post-void residual urine was measured postoperatively in 3 patients. One patient had significant post-void residual urine and required intermittent self-catheterization. The remaining 5 patients required no additional treatment. CONCLUSIONS Using the vaginal wall to reconstruct large segments of the female urethra is simple and appears to have good results. Our technique preserves the vascular axis of the flap and protects the sutures. More contributions to the existing literature are needed before any further conclusions can be drawn.

Abstract
We report the case of a 76 ys-old woman with overactive bladder syndrome, determined by an histological exam of interstitial cystitis with plasma cell infiltration. To the best of our knowledge, in literature only a similar case has been described. The patient has been treated with corticosteroid therapy allowing a transitory benefit; despite this fact, after side effects have been shown, this therapy has been interrupted leading to the worsening of the previous sintomatology. Therefore the patient has undergone to radical cystectomy with orthotopic ileal neobladder. The phlogistic infiltration of the bladder wall is represented by the plasma cells for over 90% of the whole population. In addition, blood specimen was positive for perinuclear antineutrophil cytoplasmic antibodies (p-ANCA). All these elements could hint at a chronic cystitis due to autoimmune aetiology.

Abstract
BACKGROUND Synchronous primary cortical tumors of different histology in the same kidney are rare. Preoperative awareness of this coexistence is important, since it can help in planning the surgical approach. PURPOSE To describe the imaging findings observed in five patients with two parenchymal malignant tumors of different histology in the same kidney. MATERIAL AND METHODS We reviewed the pathology reports of 381 patients operated for renal tumors from January 2000 to March 2007. The medical records of all patients with multiple, synchronous, primary lesions of different histology in the same kidney were reviewed with special attention to imaging findings and indications on the nature of the disease process. Computed tomography (CT) examinations were retrospectively evaluated for tumor detection, size, location, and enhancement pattern. RESULTS We found seven patients with synchronous tumors of different histology in the same kidney (1.8%). Among these, five (1.3%) had two malignancies of different subtypes and represent our study group. Four had preoperative ultrasound; all had CT. Imaging allowed identification of multifocality in 4/5 cases and, in 3/4 patients with visible double tumors, recognition of differences in lesion appearance. In only one patient did the two tumors have similar enhancement patterns. CONCLUSION It is possible to suspect preoperatively the presence of tumors of different histologic subtypes within the same kidney. Imaging findings may provide information regarding the presence of lesions with different aggressiveness within the kidney, which may be helpful in therapeutic planning.

Abstract
BACKGROUND After long term disease free follow up (FUp) patients reconsider quality of life (QOL) outcomes. Aim of this study is assess QoL in prostate cancer patients who are disease-free at least 5 years after radical prostatectomy (RP). METHODS 367 patients treated with RP for clinically localized pCa, without biochemical failure (PSA <or= 0.2 ng/mL) at the follow up >or= 5 years were recruited.Urinary (UF) and Sexual Function (SF), Urinary (UB) and Sexual Bother (SB) were assessed by using UCLA-PCI questionnaire. UF, UB, SF and SB were analyzed according to: treatment timing (age at time of RP, FUp duration, age at time of FUp), tumor characteristics (preoperative PSA, TNM stage, pathological Gleason score), nerve sparing (NS) procedure, and hormonal treatment (HT).We calculated the differences between 93 NS-RP without HT (group A) and 274 non-NS-RP or NS-RP with HT (group B). We evaluated the correlation between function and bother in group A according to follow-up duration. RESULTS Time since prostatectomy had a negative effect on SF and a positive effect SB (both p < 0.001). Elderly men at follow up experienced worse UF and SF (p = 0.02 and p < 0.001) and better SB (p < 0.001).Higher stage PCa negatively affected UB, SF, and SB (all: p <or= 0.05). NS was associated with better UB, SF and SB (all: p <or= 0.05); conversely, HT was associated with worse UF, SF and SB (all: p <or= 0.05).More than 8 years after prostatectomy SF of group A and B were similar. Group A subjects (NS-RP without HT) demonstrated worsening SF, but improved SB, suggesting dissociation of the correlation between SF and SB over time. CONCLUSION Older age at follow up and higher pathological stage were associated with worse QoL outcomes after RP. The direct correlation between UF and age at follow up, with no correlation between UF and age at time of RP suggests that other issues (i.e: vascular or neurogenic disorders), subsequent to RP, are determinant on urinary incontinence. After NS-RP without HT the correlation between SF and SB is maintained for 7 years, after which function and bother appear to have divergent trajectories.

Abstract
PURPOSE Pelvic lymphadenectomy is frequently performed simultaneously with radical prostatectomy to determine lymph node status and the most frequently recorded postoperative complication is the development of a symptomatic lymphocele. This study evaluated TachoSil as an adjunct treatment in preventing lymphoceles after extraperitoneal pelvic lymphadenectomy for prostate cancer. MATERIALS AND METHODS A total of 60 consecutive patients who had undergone radical prostatectomy and pelvic lymphadenectomy were prospectively enrolled in this study. The patients were randomly assigned to a standard technique with the use of clips and electrocoagulation plus TachoSil, or to standard technique only. All patients underwent ultrasound examination on postoperative days 7, 14 and 28 to test for the development of symptomatic or asymptomatic lymphoceles. Drainage volume and duration were also recorded. RESULTS The baseline characteristics of the 2 randomized groups were well matched. Those patients in whom we used TachoSil showed a lower drainage volume with a mean total volume of 64 +/- 45 ml (range 0 to 110) vs 190 +/- 62.72 ml (range 70 to 270, p = 0.009), and had significantly fewer symptomatic and asymptomatic lymphoceles (5 vs 19, p = 0.001). Only 5 percutaneous surgical procedures to drain the lymphoceles proved necessary, 1 of which occurred in the group with TachoSil. CONCLUSIONS TachoSil seems to provide a useful additional treatment option for reducing drainage volume and preventing lymphocele development after extraperitoneal radical retropubic prostatectomy with pelvic lymphadenectomy.

Abstract
We describe the case of a 34-year-old patient, polytraumatized during a motorcycle accident. The patient reported complete urethral rupture, bilateral avulsion of the testes by the scrotum, subtotal avulsion with complete amputation of the corpora cavernosa, and a deep open perineal wound. The reconstruction, performed by urologists, was postponed to the following day to ensure high standard of treatment with appropriate tools. This choice has yielded a good aesthetic and functional result.

Abstract
The coexistence of multiple, synchronous primary tumors of different histology within the same kidney is a rare condition. We report herein a series of five patients with two tumors of different histology involving synchronously the same kidney. Materials and Methods We reviewed the pathology reports of a series of 381 patients who underwent surgery for primary renal tumors at our institution from 2000 to 2007. In the files of all patients with synchronous tumors of different histology, special attention was given to the results of imaging studies. Results Five out of 381 patients (1.37%) had coexistence of two primary tumors of different histology within the same kidney. Four patients had ultrasonography as the first imaging procedure, one patient had ultrasonography as the second imaging procedure; all had preoperative CT of the abdomen. Both lesions were detected by preoperative CT in 4/5 of the cases; in the remaining one, the smaller lesion was not visible, even in retrospect. Conclusions The coexistence of multiple and synchronous primary tumors of different histology within the same kidney has been only rarely described. To the best of our knowledge, in literature there are only case reports with the exception of a case of renal oncocytoma with evolving papillary RCC. We believe that this condition could be more frequent if the radiologist and the anatomopathologist try to find it.

Abstract
Objectives The treatment of aggressive superficial TCC of the bladder remains controversial. In fact, although still classified as ‘superficial’, it has been shown that the biological characteristics of T1G3 bladder tumors are the same as those of the muscle-invasive group (T2 and above). Even with close monitoring and intensive intravesical therapy, the reported risk of muscle invasion in these patients is 53% and 1/3 die from this disease in the long-term. The aim of this study is to determine whether the timing of radical cystectomy affects the survival of patients with aggressive superficial bladder tumor. Methods We consider 74 patients who underwent radical cystectomy between November 1994 and October 2006 before a diagnosis of T1G3 bladder tumor. These patients were divided in 2 subgroups: group A (n=27, 25 M and 2 F) who underwent immediate radical cystectomy, and group B (n=47, 40 M and 7 F) who underwent other conservative treatments before radical cystectomy. Results The two subgroups were similar concerning age (66.29±8.37 yrs vs 66.87±8.6 yrs, respectively, p NS) and the timing of follow-up (respectively 77±45 vs 60±35 mths, p NS). Moreover, the progression-free survival was significantly higher in subgroup A (53.73±48.54 vs 31.94±35.19 mths, log-rank p<0.05) as well as the overall survival (59.73±45.37 vs 36.45±33.96 mths respectively, log-rank p<0.05). Comparing the histological examinations, the two subgroups were significantly different concerning the T stage (superficial tumors 14/27 vs 16/47, respectively, p<0.05; invasive tumors 13/27 vs 31/47, respectively, p<0.00005) and the lymphonodal dissemination (2N+/27 vs 11N+/47, respectively, p<<0.0005). Conclusions Delaying radical cystectomy for aggressive superficial bladder tumors leads to a worse progression-free survival; the overall survival is likely to be due also to an early lymphonodal dissemination, which occurs extending the timing between diagnosis and radical treatment.

Abstract
Objectives The introduction of PSA in clinical practice has resulted in decreasing the death rate form prostate cancer and in a downward shift of the pathological stage in radical prostatectomy specimens. This seems not to be the case for bladder cancer. In order to verify this assumption, we have reviewed the charts of the patients operated on of radical prostatectomy and radical cystectomy between 1994 and 2006. Methods 456 and 491 consecutive patients, respectively, underwent radical cystectomy and radical prostatectomy with bilateral lymph nodes dissection. We excluded all the patients who had received neoadjuvant treatment or did not undergo node dissection. The patients were divided into two consecutive groups according to the year of treatment: group 1 included pts treated from 1994 to 2000, and group 2 pts from 2001 to 2006. The histopathological findings of the two groups of pts were compared. The difference among TNM systems has been balanced evaluating histopathological reports critically and converting them to the 2002 edition. Results For patients with prostate cancer, those in group 2 had a decrease in the incidence of extracapsular extension and lymph nodes invasion. The bladder cancer patients belonging to group 2 had a greater number of T2, but there was an increased number of pN+ in this group. Conclusions Even if there is a decline in locally advanced disease in patients with bladder cancer, our retrospective analysis did not show a comparable success in early diagnosis as it did for prostate cancer. There is undoubtedly an increase in the lymph node dissemination, whether this is due to a more extended lymph node dissection or to a premature dissemination remains questionable. Public awareness regarding bladder cancer and its risk factors is limited, but several studies have reported that a delay in diagnosis of invasive bladder cancer is an adverse prognostic factor. A higher care in the development of new diagnostic markers for bladder tumors and especially in the screening protocols together with an earlier radical therapy could hopefully improve the management of such a pathology, as it happened for prostate cancer.

Abstract
CONTEXT The effects of chronic therapy with long-acting somatostatin analogs (SSTa) on metabolic and cardiovascular parameters have been partially elucidated in acromegalic patients. OBJECTIVE The objective of this study was to compare the long-term effects of SSTa treatment and successful surgery on GH/IGF-I secretion and cardiovascular risk parameters in acromegaly. DESIGN, PATIENTS, AND INTERVENTION: This was a retrospective study of 36 acromegalic patients treated with SSTa and evaluated after a median of 66 months and of 33 sex-, age-, and body mass index-matched cured patients evaluated after a similar period of remission, all from the Institute of Endocrine Sciences (Milan, Italy). MAIN OUTCOME MEASURES The main outcome measures were fasting and post-oral load glucose homeostasis, hemoglobin A(1c), insulin sensitivity and secretion by several indexes, lipid profile, and blood pressure. RESULTS Fasting and areas under the glucose response curve rose in patients controlled (n = 29) and not controlled (n = 7) by SSTa, becoming higher than those in cured subjects. A 1% hemoglobin A(1c) increase was observed in all nondiabetic SSTa patients, but not in cured subjects. Basal insulin secretion and resistance, evaluated by homeostasis model assessment, decreased in all SSTa patients, whereas oral glucose tolerance test-derived insulin secretion and resistance, evaluated by insulinogenic index and oral glucose tolerance test-derived insulin secretion, improved only in SSTa-treated controlled patients. Triglycerides did not change during SSTa, whereas high-density lipoprotein cholesterol increased in SSTa-treated controlled patients. At the last visit, the contemporary presence of at least three cardiovascular risk factors was more frequent in patients treated with SSTa than in cured subjects. CONCLUSIONS SSTa therapy induces long-lasting disease control and improvement of insulin sensitivity and high-density lipoprotein cholesterol levels in responsive patients. The progressive glucose homeostasis alterations, observed independently from the degree of cure, suggest the need for glucose homeostasis and peripheral vascular complications monitoring during chronic SSTa treatment.

Abstract
Criteria to define remission of acromegaly have changed over years. Since 2000, criteria for cure are normal IGF-I levels and a nadir GH after oral glucose tolerance test (OGTT) of less than 1 microg/liter, although recent studies have suggested to lower this cutoff value. This study reevaluated long-term disease activity of acromegalic patients, who were previously considered in remission, using these criteria. The study included 70 of 146 patients operated on between 1984 and 1996 who were considered cured based on normal IGF-I levels, GH values less than 2.5 microg/liter, and/or disappearance of abnormal GH response to TRH/GnRH. Among these 70 patients, 16 were lost to follow-up, three died, and 11 (one of whom had disease recurrence) only gave a phone interview. Forty patients participated in the study and were reevaluated for IGF-I levels and post-OGTT GH nadir after 14.3 +/- 4.2 (mean +/- sd) yr from surgery. In all patients, normal IGF-I levels and a post-OGTT GH nadir of less than 1 microg/liter were found. In particular, 19 patients had a GH nadir of less than 0.19 microg/liter, i.e. the upper limit (mean + 2 sd) found in 30 controls, whereas 21 patients had a nadir between 0.19 and 0.77 microg/liter. No significant differences in hormonal parameters and comorbidities between the two subgroups were observed. These data showed that lowering the post-OGTT GH cutoff value within the normal range does not seem to better discriminate patients with different disease activity or long-term recurrence risk.
