Outcomes and predictive factors of successful salvage microdissection testicular sperm extraction (mTESE) after failed classic TESE: results from a multicenter cross-sectional study. Int J Impot Res 2022; 34:795-799. [PMID: 34743195 DOI: 10.1038/s41443-021-00487-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Revised: 10/14/2021] [Accepted: 10/21/2021] [Indexed: 12/24/2022]
Abstract
Microdissection testicular sperm extraction (mTESE) has been proposed as a salvage treatment option for men with a previously failed classic TESE (cTESE), but data are scarce. We aimed to assess the outcome of and potential predictors of successful salvage mTESE in a cohort of men previously submitted to unfruitful cTESE. Data from 61 men who underwent mTESE after a failed cTESE between 01/2014 and 10/2020, at 6 tertiary-referral centres in Italy were analysed. All men were investigated with semen analyses, testicular ultrasound, hormonal and genetic blood testing. Pathological diagnosis from TESE was collected in every man. Descriptive statistics and logistic regression models were used to investigate potential predictors of positive sperm retrieval (SR+) after salvage mTESE. Baseline serum Follicle-Stimulating hormone (FSH) and total testosterone levels were 17.2 (8.6-30.1) mUI/mL and 4.7 (3.5-6.4) ng/mL, respectively. Sertoli-cell-only syndrome (SCOS), maturation arrest (MA) and hypospermatogenesis were found in 24 (39.3%), 21 (34.4%) and 16 (26.2%) men after cTESE, respectively. At mTESE, SR+ was found in 30 (49.2%) men. Patients with a diagnosis of hypospermatogenesis had a higher rate of SR+ (12/16 (75%)) compared to MA (12/21 (57.1%)) and SCOS (6/24 (25%)) patients at mTESE (p < 0.01). No clinical and laboratory differences were observed between SR+ and SR- patients at mTESE. There were no significant complications after mTESE. At multivariable logistic regression analysis, only hypospermatogenesis (OR 9.5; p < 0.01) was independently associated with SR+ at mTESE, after accounting for age and FSH.In conclusion, salvage mTESE in NOA men with previous negative cTESE was safe and promoted SR+ in almost 50%. A baseline pathology of hypospermatogenesis at cTESE emerged as the only independent predictor of positive outcomes at salvage mTESE.

Abstract
Abstract
Study question
We assessed the outcome and predictors of successful salvage microdissection testicular sperm extraction (mTESE) in non-obstructive azoospermia (NOA) men previously submitted to unfruitful classic (cTESE).
Summary answer
The sperm retrieval rate at salvage mTESE was almost 50%. Hypospermatogenesis and low FSH values were associated with positive outcomes at salvage mTESE
What is known already
In men with NOA testicular sperm can be retrieved using cTESE in approximately 50% of cases. mTESE has been proposed as a salvage treatment option for men with a previously failed TESE, but data are scarce.
Study design, size, duration
Multicenter, cross-sectional study. Complete data from 61 NOA men who underwent mTESE after a failed cTESE between 01/2014 and 10/2020, at 6 tertiary referral centers in Italy were analysed.
Participants/materials, setting, methods
All men underwent testicular ultrasound, hormonal and genetic blood testing. Histopathological diagnosis from TESE was collected in every man. Semen analyses were based on the 2010 WHO reference criteria. mTESE was performed according to the technique of Schlegel et al. (1999). Descriptive statistics and logistic regression models were used to investigate potential predictors of positive sperm retrieval (SR+) after salvage mTESE.
Main results and the role of chance
Overall, median (IQR) age and testicular volume were 35 (31–38) years and 10 (6–15) ml, respectively. Baseline serum FSH and total testosterone levels were 17.1 (8.6–30.4) mUI/mL and 4.7 (3.5–6.4) ng/mL, respectively. Sertoli-cell-only (SCO) syndrome, maturation arrest (MA) and hypospermatogenesis were found in 24 (39.3%), 21 (34.4%) and 16 (26.2%) men after cTESE, respectively. Spermatozoa were retrieved in 30 (49.2%) men at salvage mTESE. Patients with a diagnosis of hypospermatogenesis had a higher rate of SR + [12/16 (75%)] than those with MA [12/21 (57.1%)] and SCOS [6/24 (25%)] after salvage mTESE (p < 0.01), which was bilateral in 36 (59%) cases. FSH was higher [16.5 (8–22) vs. 8.9 (5–13) mUI/mL, p < 0.01] in SR- patients compared to SR+. No difference in clinical characteristics was found between patients with SR+ and SR- at salvage mTESE. There were no significant complications after mTESE. Multivariable logistic regression analysis showed that hypospermatogenesis (OR 9.7; p < 0.01) and low FSH levels (OR 0.9, p < 0.001) were independent predictors of SR+ after salvage mTESE, after accounting for age.
Limitations, reasons for caution
Despite we analysed one of the largest series of salvage mTESE, the samples size is too small to draw general conclusions. Because of the multicenter nature of the study we cannot rely on standardization of surgical techniques for TESE.
Wider implications of the findings: This is one of the larger studies on salvage mTESE. The selection of patients for salvage mTESE is of critical importance.

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.

Retroperitoneal approach for robot-assisted partial nephrectomy: technique and early outcomes. Int Braz J Urol 2018; 44:63-68. [PMID: 29211396 PMCID: PMC5815533 DOI: 10.1590/s1677-5538.ibju.2017.0104] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2017] [Accepted: 08/07/2017] [Indexed: 01/20/2023] Open
Abstract
OBJECTIVES The aim of our study is to present early outcomes of our series of retroperitoneal-RAPN (Robot Assisted Partial Nephrectomy). MATERIALS AND METHODS From September 2010 until December 2015, we performed 81 RAPN procedures (44 at left kidney and 37 at right). Average size was 3cm (1-9). Average PADUA score 7.1 (5-10). Average surgical time (overall and only robot time), ischemia time, blood loss, pathological stage, complications and hospital stay have been recorded. RESULTS All of the cases were completed successfully without any operative complication or surgical conversion. Average surgical time was 177 minutes (75-340). Operative time was 145 minutes (80-300), overall blood loss was 142cc (60-310cc). In 30 cases the pedicle was late clamped with an average ischemia time of 4 minutes (2-7). None of the patient had positive surgical margins at definitive histology (49pT1a, 12pT1b, 3pT2a, 2pT3a). Hospital stay was 3 days (2-7). CONCLUSIONS The retroperitoneal robotic partial nephrectomy approach is safe and allows treatment of even quite complex tumors. It also combines the already well known advantages guaranteed by the da Vinci® robotic surgical system, with the advantages of the retroperitoneoscopic approach.

Abstract
BACKGROUND To report the perioperative and early functional outcomes of patients undergoing Robot-assisted radical cystectomy (RARC) with totally intracorporeal urinary diversion performed by a single surgeon after a modified modular training. METHODS The surgeon (A.P.) attained a 30-days modified modular training at a referring Center mentored by a worldwide-recognized robotic surgeon (P.W.). The training program consisted of: 1) e-learning based on 10 hours of theoretical lessons made by the mentor; 2) video-session concerning the different steps of the procedure, 3) step-by-step in vivo modular training. Demographics, intraoperative data and post-operative complications were recorded for each patient. RESULTS Twenty-four consecutive patients were prospectively evaluated. Median age was 68.5 years (IQR 59-75). Thirteen (54.2%) and 11 (45.8%) patients received RARC with orthotopic neobladder (ONB) and ileal conduit (IC), respectively. Overall mean (±SD) operative time was 392 (± 34.8) minutes. The median number of lymph node retrieved was 30 (IQR 24-42), the mean intraoperative estimated blood loss (EBL) was 403 mL (±60) with average hospitalization of 7.8 days (±2.2). All procedures were completed successfully without open conversion. A statistically significant difference in terms of overall operative time (OT) and urinary diversion operative time (UDOT) was found in favor of IC group compared to ONB group (P=0.002). Overall complication rate was 33%, 7 out of 9 (88%) were graded as minor (Clavien 1-2). Two (22%) major complications (Clavien 3-5) occurred solely on ONB group. CONCLUSIONS Robot-assisted radical cystectomy with totally intracorporeal urinary diversion is a challenging procedure with a steep learning curve. An adequate modular training with an experienced mentor and a skilled robotic team could be essential to reach these optimal results. Further studies investigating the impact of modular learning curve and a dedicated menthorship on operative and functional outcomes after RARC are needed.

Abstract
The treatment of ureteral strictures represents a challenge due to the variability of aetiology, site and extension of the stricture; it ranges from an end-to-end anastomosis or reimplantation into the bladder with a Boari flap or Psoas Hitch. Traditionally, these procedures have been done using an open access, but minimally invasive approaches have gained acceptance. The aim of this study is to evaluate the safety and feasibility and perioperative results of minimally invasive surgery for the treatment of ureteral stenosis with a long-term follow-up. Data of 62 laparoscopic (n = 36) and robotic (n = 26) treatments for ureteral stenosis in 9 Italian centers were reviewed. Patients were followed according to the referring center's protocol. Laparoscopic and robotic approaches were compared. All the procedures were completed successfully without open conversion. Average estimated blood loss in the two groups was 91.2 ± 71.9 cc for the laparoscopic and 47.2 ± 32.3 cc for the robotic, respectively (p = 0.004). Mean days of hospitalization were 5.9 ± 2.4 for the laparoscopic group and 7.6 ± 3.4 for the robotic group (p = 0.006). No differences were found in terms of operative time and post-operative complications. After a median follow-up of 27 months, the robotic group yielded 2 stenosis recurrence, instead the laparoscopic group shows no cases of recurrence (p = 0.091). Minimally invasive approach for ureteral stenosis is safe and feasible. Both robotic and pure laparoscopic approaches may offer good results in terms of perioperative outcomes, low incidence of complications and recurrence.

A novel stepwise micro-TESE approach in non obstructive azoospermia. BMC Urol 2016; 16:20.

Abstract
Background The purpose of the study was to investigate whether micro-TESE can improve sperm retrieval rate (SRR) compared to conventional single TESE biopsy on the same testicle or to contralateral multiple TESE, by employing a novel stepwise micro-TESE approach in a population of poor prognosis patients with non-obstructive azoospermia (NOA). Methods Sixty-four poor prognosis NOA men undergoing surgical testicular sperm retrieval for ICSI, from March 2007 to April 2013, were included in this study. Patients inclusion criteria were a) previous unsuccessful TESE, b) unfavorable histology (SCOS, MA, sclerahyalinosis), c) Klinefelter syndrome. We employed a stepwise micro-TESE consisting three-steps: 1) single conventional TESE biopsy; 2) micro-TESE on the same testis; 3) contralateral multiple TESE. Results SRR was 28.1 % (18/64). Sperm was obtained in both the initial single conventional TESE and in the following micro-TESE. The positive or negative sperm retrieval was further confirmed by a contralateral multiple TESE, when performed. No significant pre-operative predictors of sperm retrieval, including patients’ age, previous negative TESE or serological markers (LH, FSH, inhibin B), were observed at univariate or multivariate analysis. Micro-TESE (step 2) did not improve sperm retrieval as compared to single TESE biopsy on the same testicle (step 1) or multiple contralateral TESE (step 3). Conclusions Stepwise micro-TESE could represent an optimal approach for sperm retrieval in NOA men. In our view, it should be offered to NOA patients in order to gradually increase surgical invasiveness, when necessary. Stepwise micro-TESE might also reduce the costs, time and efforts involved in surgery.

Abstract
AIM The aim of the present work was to describe authors' surgical experience using the partial nephrectomy technique without intraoperatory pedicle clamping for masses even up to 4 cm of size. METHODS The study enrolled 96 patients with an average age of 59.7 years, who underwent partial nephrectomy without pedicle clamping. The average dimensions of the masses treated were 3.7x3x3.8. In preoperative and in postoperative time creatinine, hemoglobine, hematocrit and platelets were monitored. The follow-up was of 1-3-6 months. At the third month postoperatively a renal US scan was performed, together with a control CT scan and at the sixth month of follow-up the patients underwent also a control Tc99/DMSA renal scintigraphy in back, front, oblique and right posterior oblique left rear projections. RESULTS Surgery and anesthesia time have been respectively of 1 h 51 min e 2 h 30 min. In the postoperative time the average values were: creatinine 1.46 ng/mL (±0.45), hemoglobin: 11.25 g/dL (±1.6), hematocrit: 36.4 % (±3), platelets: 205 x 103 (±45 x 103). At follow-up at 1-3-6 months the average values were: creatinine 1.16 ng/dL (±0.66), hemoglobin 14.13 g/dL (±0.13), hematocrit 42.43% (±1.03), platelets 204 x 103 U/L (±1.66 x103). After six months the renal function demonstrated intraparenchymal homogeneous distribution of the drug in all the patients, with a 7% of difference of relative uptake by the operated kidney than the healthy controlateral one. CONCLUSION The partial nephrectomy without intraoperative pedicle clamping can be a good therapeutic option for the treatment of kidney cancer for masses even up to 4 cm of size. The follow-up should be longer to assess oncological results.

Abstract
BackgroundCystocele is connected to an ingravescent relaxation of uretrovesical support system. During surgical correction of this disease, a mesh has been introduced to strengthen weak tissue. The aim of the study was to compare different material aspects and various devices.MethodsFrom June 2002 to December 2008, 80 patients underwent surgical correction for high-degree cystocele. None of the patients had stress-incontinence. All the patients were studied with cistography and urodynamic test. Three different kinds of mesh were employed, such as: Goretex (26 pt.), Prolene (27 pt.), Bovine Pericardium (27 pt.). During surgery the mesh have been modelled if necessary and fixed by detached sutures.ResultsBy comparing the devices: in Goretex group there were excellent results about anatomical correction, in the follow-up too (6 months), good continence and an improving of quality of life; in Prolene group no post-surgery complication, 3 pts. referred urge incontinence resolved in about 3 months. After 6 months a subset of patients reported sensation of foreign vulvar body and moderate dyspareunia; in Bovine Pericardium group we had an intra-operatory difficulty, for its softness a high risk to tear the net itself. No post-surgery complications. No urinary symptoms. After 3 months 5 of the patients referred a sensation of foreign vulvar body and dyspareunia. After 6 months, 4 patients still have the same sensation.ConclusionWe hypothesize that Goretex mesh is an excellent device for its operator manageability, good anatomical results, and good tolerability. Further investigation is warranted to determine the effect of each of these techniques.
