Partial nephrectomy has become a treatment of choice for clinical T1a renal masses. Some international guidelines suggest that partial nephrectomy can be applied also in clinical T1b tumors. The aim of this study was to evaluate the feasibility of partial nephrectomy for tumors larger than 4 cm. We reviewed the medical records of 1280 patients who underwent partial nephrectomy and had pathologically confirmed malignancy. Patients were categorized into two groups by the size of tumors on computed tomography image, with a cutoff value of 4 cm. The oncologic and functional outcomes were compared between the two groups. Recurrence-free survival after surgery was estimated using the Kaplan-Meier method. Of the 1280 patients, 203 patients (15.9%) had renal tumors larger than 4 cm. There were significantly more exophytic tumors (P < 0.001) and the R.E.N.A.L. scores were significantly higher (P < 0.001) in partial nephrectomy >4 cm. Mean ischemic times were significantly different (P < 0.001). After 24 months, mean creatinine level between partial nephrectomy >4 cm and partial nephrectomy ≤4 cm was not different significantly (P = 0.554). And the percent changes of glomerular filtration rate after partial nephrectomy were not different at last follow-up (P = 0.082). The 5-year recurrence-free survival rates were 96.6% in partial nephrectomy ≤4 cm, and 94.5% in partial nephrectomy >4 cm (P = 0.416). Based on the present findings, partial nephrectomy for tumors larger than 4 cm showed comparable feasibility and safety to partial nephrectomy for tumors ≤4 cm considering oncologic and functional outcomes, despite longer operative and ischemic time.

Historically, radical nephrectomy represented the gold standard for the treatment of small (? 4cm) as well as larger renal masses.  Recently, for small renal masses, the risk of ensuing chronic kidney disease and end stage renal disease has largely favored nephron-sparing surgical techniques, mainly partial nephrectomy. In this review, we surveyed the literature on renal functional outcomes after partial nephrectomy for renal tumors. The largest randomized control trial comparing radical and partial nephrectomy failed to show a survival benefit for partial nephrectomy. With regards to overall survival, surgically induced chronic kidney disease (GFR < 60 ml/min/ 1.73m2) caused by nephrectomy might not be as deleterious as medically induced chronic kidney disease. In evaluating patients who underwent donor nephrectomy, transplant literature further validates that surgically induced reductions in GFR may not affect patient survival, unlike medically induced GFR declines.  Yet, because patients who present with a renal mass tend to be elderly with multiple comorbidities, many develop a mixed picture of medically, and surgically-induced renal disease after extirpative renal surgery.  In this population, we believe that nephron sparing surgery optimizes oncological control while protecting renal function.

Objectives: To compare perioperative, oncological and functional outcomes of Laparoscopic Transperitoneal Partial Nephrectomy (LTPN) and Retroperitoneal Laparoscopic Partial Nephrectomy (LRPN) for posterior, cT1 renal masses (RMs). Materials and methods: Databases of two urologic institutions applying different laparoscopic surgical approaches on posterior cT1 RMs between June 2016 and November 2018 were retrospectively evaluated. Data on patient demographics, perioperative data and tumor histology were collected and further analyzed statistically. Results: Each group consisted of 15 patients. Baseline characteristics were comparable in each group. When compared to LTPN, LRPN was associated with significantly shorter operative time (OT) (115 min versus 199 min, p < 0.05). No significant differences were detected in the other outcomes. Conclusions: LRPN is associated with a significantly shorter OT compared to LTPN for posterior cT1 RMs. Both surgical approaches are safe, feasible and credible, demonstrating optimal results.

Abstract Purpose To retrospectively investigate long-term outcomes of renal cryoablation from a multicenter database. Methods 338 patients with 363 renal tumors underwent cryoablation in 4 centers in North-Eastern Italy. 340/363 tumors (93.7%) were percutaneously treated with CT guidance. 234 (68.8%) were treated after conscious sedation, 76 (22.3%) under local lidocaine anesthesia only and 30 (8.8%) under general anesthesia. Treatment efficacy and complication rate considered all procedures. Oncologic outcomes considered a subset of 159 patients with 159 biopsy proven renal cell carcinoma. Results Mean tumor size was 2.53 cm. Technical success was achieved in 355/363 (97.8%) treatments. Treatment efficacy after the first treatment was achieved in 348/363 (95.9%) tumors. Statistical analysis revealed a significant lower treatment efficacy for ASA score >3, Padua score >8, tumor size >2.5 cm, use of >2 cryoprobes, presence of one single kidney. In the subset of 159 patients, recurrence-free survival rates were 90.5% (95% CI 83.0%, 94.9%) at 3 years and 82.4% (95% CI 72.0%, 89.4%) at 5 years; overall survival rates were 96.0% (95% CI 90.6%, 98.3%) at 3 years and 91.0% (95% CI 81.7%, 95.7%) at 5 years; no patient in this subset developed metastatic disease. Clavien-Dindo >1 complications were recorded in 14/369 procedures (3.8%) and were related to age >70 years, tumor size >4 cm and use of >2 cryoprobes. Conclusion Cryoablation performed across four different centers in a large cohort of predominantly small renal tumors showed that this technique provides good recurrence-free survival rates and overall survival rates at three- and five-year with very low major complications rate.

Abstract Objectives Patients with haemoptysis often experience daily physical and mental impairment. Bronchial artery embolisation is among the first-line treatment options used worldwide; however, no evidence exists regarding the health-related quality of life (HRQoL) after bronchial artery embolisation. Therefore, this study aimed to evaluate the effects of bronchial artery embolisation on the HRQoL of patients with haemoptysis. Methods We prospectively enrolled 61 consecutive patients who visited our hospital from July 2017 to August 2018 and received bronchial artery embolisation for haemoptysis. The primary outcome was the HRQoL evaluated using the Short Form Health Survey, which contains physical and mental components, before and after bronchial artery embolisation. The secondary outcomes were procedural success, complications, and recurrence-free survival rate at 6 months. Results The mean age of the patients was 69 years (range, 31–87 years). The procedural success rate was 98%. No major complications occurred. The recurrence-free survival rate estimated using the Kaplan-Meier analysis at 6 months after bronchial artery embolisation was 91.8% (95% confidence interval, 91.1–92.5%). Compared with the pre-treatment scores, the physical and mental scores were significantly improved at 6 months after bronchial artery embolisation (p < 0.05). Conclusion Bronchial artery embolisation improved the HRQoL of patients with haemoptysis. Key Points • Bronchial artery embolisation improved the HRQoL of patients with haemoptysis. • Vessel dilation on computed tomography and systemic artery-pulmonary artery direct shunting on angiography were the most common abnormalities. • The recurrence-free survival rate estimated using the Kaplan-Meier analysis at 6 months after bronchial artery embolisation was 91.8%.

Introduction: Many medical associations recommend nephron-sparing surgery (NSS) for tumours larger than 4 cm amenable to partial nephrectomy (PN). These recommendations are, however, mostly based on isolated reports. We systematically review the oncological outcomes of partial nephrectomy procedures performed for tumours larger than 4-cm.Methods: A PubMed search was carried out using keywords “partial nephrectomy” and “nephron sparing” for records dating back to 1995. In total, 2136 abstracts were analyzed; from these, 174 studies were scrutinized. We identified 32 manuscripts reporting size-specific cancer-specific survival rates for masses greater than 4 cm. From each of these studies, we recorded the number of PN, tumour diameter, follow-up duration, 5- and 10-year recurrence, overall and cancer-specific survival rates (OS, CSS). We also calculated weighted OS and CSS rates.Results: This systematic review includes 2445 patients with renal tumours larger than 4 cm who underwent PN: 1858 patients with tumours between 4 to 7 cm, 410 patients with tumours larger than 7 cm and 177 patients with tumours greater than 4 cm (exact size unknown). Our analysis revealed weighted 5-year CSS rates of 95.4%, 86.2% and 93.9% for tumours 4 to 7 cm, >7 cm, and all tumours >4 cm, respectively. The respective 5-year OS rates were 84.7%, 76.4%, and 84.7%.Conclusions: We found excellent 5-year CSS and OS rates for patients with tumours 4 to 7 cm treated with PN. These outcomes compare favourably to those reported in historical radical nephrectomy (RN) series for similarly sized tumours. Thus, PN is an acceptable and often preferred treatment for renal masses >4 cm which are amenable to nephron-sparing procedures.

Purpose: To analyze and compare the results of robotic partial nephrectomy (RPN) at a single center with the previous large-scale studies in terms of perioperative and oncological outcomes.Materials and Methods: We retrospectively evaluated 1,013 cases of RPN in our center database from December 2008 to August 2018. Total 11 cases were excluded in final analysis. We evaluated perioperative outcomes as the Trifecta achievement, which is defined as no positive surgical margin (PSM), no perioperative complications greater than Clavien-Dindo classification I and a warm ischemia time of <25 minutes. In addition, we analyzed pathological and oncological outcomes; recurrence, metastasis, all-cause deaths, cancer-specific deaths, and 5-year survival rates.Results: In 1,002 cases, the Trifecta achievement was 61.1% (n=612). The postoperative complication was 18.4% (n=184) but most were grade 2 or less (14.9%, n=145). Ninety-three cases (9.28%) had benign and 907 cases (90.5%) had malignant pathologies. A local recurrence were 14 cases (1.54%) and distant metastasis were 20 cases (2.2%) during follow-up periods. Allcause death rate was 1.2% (n=11) and cancer-specific death rate was 0.2% (n=2). The median follow-up period was 39 months. A 5-year recurrence-free survival rate, cancer-specific survival rate, and overall survival rate were 95.2%, 99.7%, and 98.4%.Conclusions: In summary, our data shows comparable perioperative outcomes to other largescale studies of RPN in terms of the Trifecta achievement with similar baseline characteristics. In terms of oncological outcomes, there was lower rate of PSM and similar recurrence free survival rate.

Background and Purpose: The European Association of Urology guidelines recommend restaging transurethral resection of bladder tumours (reTURB) 2–6 weeks after primary TURB. However, in clinical practice some patients undergo a second TURB procedure after Bacillus Calmette-Guérin immunotherapy (BCG)induction. To date, there are no studies comparing post-BCG reTURB with the classic pre-BCG approach. The aim of this study was to assess whether the performance of reTURB after BCG induction in T1HG bladder cancer is related to potential oncological benefits. Materials and Methods: Data from 645 patients with primary T1HG bladder cancer treated between 2001 and 2019 in 12 tertiary care centres were retrospectively reviewed. The study included patients who underwent reTURB before BCG induction (Pre-BCG group: 397 patients; 61.6%) and those who had reTURB performed after BCG induction (Post-BCG group: 248 patients, 38.4%). The decision to perform reTURB before or after BCG induction was according to the surgeon’s discretion, as well as a consideration of local proceedings and protocols. Due to variation in patients’ characteristics, both propensity-score-matched analysis (PSM) and inverse-probability weighting (IPW) were implemented. Results: The five-year recurrence-free survival (RFS) was 64.7% and 69.1% for the Pre- and Post-BCG groups, respectively, and progression-free survival (PFS) was 82.7% and 83.3% for the Pre- and Post-BCG groups, respectively (both: p > 0.05). Similarly, neither RFS nor PFS differed significantly for a five-year period or in the whole time of observation after the PSM and IPW matching methods were used. Conclusions: Our results suggest that there might be no difference in recurrence-free survival and progression-free survival rates, regardless of whether patients have reTURB performed before or after BCG induction.
