Ureteral access sheath-related injuries vs. post-operative infections. Is sheath insertion always needed? A prospective randomized study to understand the lights and shadows of this practice.

OBJECTIVE: To compare intraoperative ureteral injuries in RIRS with UAS insertion with the rate of postoperative infections after RIRS without UAS insertion. PATIENTS AND METHODS: In this randomized trial, patients who received an indication for RIRS between January 2017 and December 2017 were divided into two groups. Group A had no UAS insertion and Group B had UAS insertion. Post-Ureteroscopic Lesion Scale (PULS) grading was performed after UAS or flexible ureteroscope removal. Proximal, middle and distal ureteral lesions were evaluated and compared according to the PULS scale. Additionally, patients in both groups were followed postoperatively to assess any infective complication. RESULTS: The evaluation comprised 181 patients, 89 for group A and 92 for group B. Overall stone-free rate, clinically insignificant residual fragments, and final stone-free rate were 41.4%, 53.5%, and 95%, respectively. There were 33 (37.1%) patients with ureteral lesions in group A while 42 (45.6%) patients had ureteral lesions in group B, with no significant difference. On the other hand, the overall presence of postoperative infection rate was much higher for Group A (37.1% vs 16.3% P = 0.03). CONCLUSIONS: UAS insertion does not result in a higher number of ureteral injuries. UAS insertion during RIRS allows a lower rate of postoperative infections.

Is psychiatric residential facility discharge possible and predictable? A multivariate analytical approach applied to a prospective study in Italy.

BACKGROUND: A growing number of severely ill patients require long-term care in non-hospital residential facilities (RFs). Despite the magnitude of this development, longitudinal studies surveying fairly large resident samples and yielding important information on this population have been very few. AIMS: The aims of the study were (1) to describe the socio-demographic, clinical, and treatment-related characteristics of RF patients during an index period in 2010; (2) to identify predictors and characteristics associated with discharge at the 1-year follow-up; (3) to evaluate clinicians' predictions about each patient's likelihood of home discharge (HD). METHODS: A prospective observational cohort study was conducted involving all patients staying in 23 medium-long-term RFs of the St John of God Order with a primary psychiatric diagnosis. A comprehensive set of socio-demographic, clinical, and treatment-related information was gathered and standardized assessments (BPRS, HONOS, PSP, PHI, SLOF, RBANS) were administered to each participant. Logistic regression analyses were run to identify independent discharge predictors. RESULTS: The study involved 403 patients (66.7% male), with a mean age of 49 years (SD = 10). The participants' average illness duration was 23 years; median value for length of stay in the RF was 2.2 years. The most frequent diagnosis was schizophrenia (67.5%). 104 (25.8%) were discharged: 13.6% to home, 8.2% to other RFs, 2.2% to supported housing, and 1.5% to prison. Clinicians' predictions about HD were generally erroneous. CONCLUSIONS: Very few patients were discharged to independent accommodations after 1 year. The main variables associated with a higher HD likelihood were: illness duration of <15 years and effective social support during the previous year. Lower severity of psychopathology and higher working skill levels were also associated with a significantly greater HD likelihood.

Attitude towards psychiatric patients: a pilot study in a northern Italian town.

The stigmatisation of the psychiatric patient is still a strong barrier to the integration process of these subjects in our society. Therefore, it is necessary to identify what types of prejudices exist and the types of variables with which they are linked, in order to plan strategies to reduce them. In this exploratory study we administered a semi-structured interview to 303 subjects in order to examine the relationships between social attitudes towards mental disorders and some social demographic variables, the information about mental disorders and the previous 'contacts' with psychiatric patients. The data analysis shows that there is a relationship between knowledge of psychiatric patients and a more positive attitude towards them (i.e., less fear, more integration and work opportunities). This study is to be considered preliminary as far as people's attitudes towards psychiatric patients are concerned. This result encourages the planning and implementation of sensitisation and information programs concerning mental disorders, in the sense that increasing the knowledge of mental disorders could lead to significant achievements in the important fight against the stigma surrounding psychiatric patients.

[Urologic laparoscopy in day hospital]. / Laparoscopia urologica in Day Hospital.

Thanks to the less invasiveness that is the limitation of the surgical trauma, the utilization of laparoscopic techniques for managing a wide range of urological disorders has vastly expanded over the past five years. The advantages of less postoperative pain, shorter convalescence and decreased analgesic use collide with the high costs and the necessity of a proper training. Few cases are reported in the literature about urological laparoscopic procedures performed on an outpatient basis. This is due to the requirement of the general anesthesia in most cases with prolonged operative and anesthesiological times. Urological laparoscopic procedures are applicable on an outpatient basis only if the length of the surgery is less than two hours and the patients are able to collaborate and without concurrent medical problems. Therefore we think that the urological laparoscopic diagnostic procedures feasible on an outpatient basis could be: pelvic lymphadenectomy, identification of intra-abdominal testis and intersex, renal biopsy. Varicocelectomy, intra-abdominal orchiectomy, renal cyst resection, pelvic lymphocelectomy and bladder neck suspension can be performed as same-day surgery. We emphasize that the appropriate patient selection is critical: the ability of the patient and his family to care for the patient at home following surgery is of paramount importance in the decision to proceed with outpatient surgery. The availability of appropriately trained and experienced doctors and nurses are crucial for the potential postoperative complications.

[Conservative therapy in renal carcinoma: follow-up]. / Terapia conservativa nel carcinoma renale: follow up.

Due to the increasing use of sophisticated imaging techniques, up to 30% of diagnosed renal cell carcinoma (RCC) are asymptomatic and diagnosed incidentally. Getting the cue from our personal survey of conservative renal surgery for renal cell carcinoma with a cancer specific survival of 95.5% after a mean follow up of 32.7 months, a review of the literature is illustrated: numerous studies have documented the technical success rate with this approach as well as long term disease free survival, comparable to that obtained by radical nephrectomy, in patients with unilateral, small, low stage tumors and normal opposite kidney. Patient selection is of extreme importance in case of partial resection in the presence of a normal contralateral kidney. The tumor must be < 3-4 cm, solitary, well delineated on CT, without invasion of the perinephric far or pyelocaliceal system (T1 and T2), easily resectable with at least 1 cm of healthy parenchyma. Only well informed patients who agree on a careful follow up after surgery can be candidates for kidney sparing surgery. In case of imperative surgery the follow up must be strict and personified for every single patient. Those patients who underwent a partial nephrectomy in presence of a normal contralateral kidney should be monitored with a conventional follow up monitored in order to detect an eventual local recurrence: 12 monthly ultrasonography and contrast enhanced CT scan alternately every 6 months for the first five years after surgery and then lifelong once a year by echography and/or CT scan.

[100 orthotopic neobladders in men after cystectomy: a 5-year experience]. / 100 neovesciche ortotopiche nel maschio cistectomizzato: esperienza di 5 anni.

Urethral bladder substitution is traditionally suggested to good prognosis cystectomized patients. In our series this diversion was chosen for all but the salvage cystectomized men. Between the 1st of February 1991 and the 30th of April 1996, one hundred consecutive men underwent lower urinary tract reconstruction after radical cystoprostatectomy for bladder cancer. An orthotopic ileal neobladder was constructed (in 84 cases according to Kock's technique and in 16 to Studer's technique). Total early complication rate was 29% (29/100), including one perioperative death due to sepsis (mortality rate 1%). 13 patients required surgery (6 retroperitoneal hematomas, 2 wound dehiscences, 1 urinary fistula, 1 lymphocele, 1 rectal-neobladder fistula, 1 rectal-cutaneous fistula, 1 necrosis of the terminal ureter). The late complication rate was 19% (19/100); in 8 cases reparative surgery was required (1 mechanical ileus, 2 bladder neck stenoses, 3 stenoses of the ureteral anastomosis, 2 laparoceles). Four patients were lost at the follow-up; out of the 96 remaining patients only 85 were evaluable for continence: continence during the day was achieved in a period between there to six months in 78 patients (91.7%); night continence was achieved with planned awakenings in 60 patients (70.5%). Eight patients recovered potency, another 7 had successful intercourses after PGE1 intracavernous injection. Renal function based on creatinine value was mildly impaired in 5/78 evaluable patients (6.4%) (peak creatinine 2.8 mg%). In 29 patients tumour progression was observed (29%): 9 pelvic and 20 metastatic. Among the latter 2 urethral recurrences were observed (2%). Twenty-four patients died for metastatic cancer, one for primitive lung cancer, one patient for postoperative septic shock. Adjuvant chemotherapy was administered in 11 patients without complication with an indwelling catheter in the neobladder to avoid drug reabsorption. Four patients showed complete response (2 are alive after a mean of 12 months), 6 were non responders and 1 had a partial response. In our series the ileal neobladder is a feasible method of urinary diversion when urethral cancer involvement is ruled out. Early and late complications are proportionally decreasing with experience and overall continence is satisfactory. The fate of the neobladder depends on both the technique and patient's compliance. Only educated patients can cope successfully with neobladder diversion without major complications. All the patients operated for non salvage cystectomy deserve to be diverted with a continent urethral bladder substitution.

Is laparoscopy a worthy method to treat varicocele? Comparison between 160 cases of two-port laparoscopic and 120 cases of open inguinal spermatic vein ligation.

Because it is still a puzzling debate whether ligation of a unilateral varicose spermatic vein is worth performing by laparoscopy, even with the two-port technique, we conducted a study in which 280 patients with palpable left varicoceles were treated with spermatic vein ligation either by open surgery (120 patients) or by laparoscopy (160 patients). The inclusion criteria were the same for each group, and the two groups were homogeneous in preoperative clinical features and patient characteristics. The clinical outcomes were compared 6 months after surgery, and the costs of each treatment were analyzed. The procedures showed the same effectiveness and intraoperative safety. Open surgery scored a shorter operating time, whereas hospitalization was significantly shorter in the laparoscopic group. Postoperative complications occurred more frequently in the open surgery than in the laparoscopic group (7.5% and 0.6%, respectively). Of the patients treated, 197 were eligible for seminal analysis: 82 and 115 in the open surgery and laparoscopic groups, respectively. Significant improvement in seminal analysis was recorded in both groups, whereas no difference was found between the groups. Laparoscopy costs about 60% more than open surgery. It can thus be concluded that laparoscopy is not a worthy method to treat unilateral varicocele.

[T1G3 of the bladder: our experience]. / T1G3 della vescica: la nostra esperienza.

From June 1991 to June 1995 we treated 20 patients affected by T1 G3 TCC of the bladder, 18 men and 2 women, with a mean age of 65.1 years (46-71). In 11 patients the disease was monofocal, with diameter of the tumor under 3.5 cms; in 5 patients monofocal with diameter of the tumor over 3.5 cms; in 1 patient multifocal and in 3 patients complex (mono or multifocal associated with CIS). The 11 patients with monofocal disease under 3.5 cms were treated with TUR-B, the other 9 (all males) were submitted to radical cystectomy with OINB diversion as first choice treatment. The mean follow up (all patients) was 3.2 years (6 months-14 years). Out of the patients of the former group only 3 did not show any relapse, the other 8 showed multiple relapses or metachronous tumors: 5 were treated with TUR-B+BCG, 3 were cystectomized. The patients submitted to cystectomy as first choice treatment did not show any progression of the disease after a mean follow-up of 19.8 months.

[Physiopathology of BPH obstruction]. / Fisiopatologia dell'ostruzione da IPB.

The underlying BPH related mechanisms of outlet obstruction are outlined (modification of the shape of the bladder neck, failure of funnel formation, geometric variations of the urethra, alpha 1 adrenoceptors mediated sympathetic hyperactivity at the level of the lower genito-urinary tract). Bladder voiding dysfunction in response to prostate obstruction is also discussed and correlated to ultrastructural patterns and clinical symptoms. Finally, a pathogenetic mechanism for detrusor overactivity in obstructed bladder is suggested.

[Alpha blockers, TUS-P and TUR-P in the treatment of benign prostatic hypertrophy. A comparison using multivariate statistical analysis]. / Alfa-litici, TUS-P, TUR-P nel trattamento dell'IPB. Confronto con analisi statistica multivariata.

To evaluate the effectiveness of Alpha-blockers, TUI-P and TUR-P in the treatment of obstruction due to BPH, 50 patients, never before treated, were considered. Fifteen were treated with alfuzosin chlorhydrate 7.5 mg/day for four months, 15 were submitted to TUI-P and 20 to TUR-P. In all patients linear purr was carried out before treatment and was repeated from 60 to 90 days after intervention in surgical patients and during the fourth month of treatment in patients treated with alfuzosin. The data obtained were analyzed with the T-test both for dependent and independent samples. The results show that Alpha-blocker contain an increase in maximal flow, without decreasing bladder voiding pressures. On the contrary TUI-P and TUR-P, besides the increase in maximal flow obtain a significant reduction of bladder pressures. The conclusions are the following: maximal flow alone is not a sufficient parameter to evaluate the work of the bladder, the entity of the obstruction and the effectiveness of the therapy. The treatment with Alpha-blockers is unable to reduce the obstruction due to BPH. TUI-P and TUR-P realize an effective deobstruction. Under the same deobstructing effect TUR-P assures a better voiding performance by obtaining higher flow values.

Retroperitoneoscopy.

From October 1992 to June 1994, 12 nephrectomies (all for benign diseases), one nephropexy and 7 adrenalectomies (one pheochromocitoma, three adenomas, one cyst) were performed. In all the cases the retroperitoneal working space was created with direct CO2 insufflation (without balloon) with the patient in prone position. Four 10-12 mm ports were always inserted in the lumbar area. Eighteen procedures were successful (90%), 2 failed (one nephrectomy and one adrenalectomy) and underwent open surgery. Twelve procedures were carried out with the patients in prone position, six (one nephropexy and 5 nephrectomies) were performed with the patients in lateral de cubitus. The removal of organs was managed either through an enlarged port (phi 2 cm.) or by joining vertically the stabs of the two ports lateral to the sarcospinalis muscle. The average operative time was 4.10 hours) range 2.30-5.20). Both CO2 absorption and blood loss were negligible. No major complications were observed. Postoperative pain never required medications. All patients were able to stand on the 1st postoperative day. Mean postoperative hospitalisation was 4 days. Direct retroperitoneal approach provides optimal access for laparoscopic renal, proximal ureteral and adrenal surgery, avoiding extensive dissection and handling of intraperitoneal structures.

[Familial multiple bilateral carcinoma of the kidney: clinical strategy and surgical approach]. / Carcinoma renale bilaterale multiplo familiare: strategia clinica e tattica chirurgica.

A case of familiar bilateral multicentric RCC in a young woman is an ideal model to evaluate preoperative and intraoperative diagnostic and surgical tools in order to achieve two distinct goals: the oncologic radicalness and the renal function preserved. Radical bilateral nephrectomy, the renal hypothermia by perfusion of both kidneys, the bench high resolution sonography of parenchyma, the choose of one kidney suitable for conservative surgery, the resection of suspect lesions with intraoperative pathology, the reconstructive bench surgery, the autotransplantation, are the steps accurately performed with particular concern to eradication of all the tumoral lesions present in the kidneys. The results confirm that renal function has been preserved with this method. Radicalness should be appointed by a longlasting follow up. However, as it is discussed, conservative surgery, when accurately performed can give results not different from radical demolitive surgery. In this paper tools to improve diagnostic and therapeutic methods are described in order to increase the diagnostic accuracy and the therapeutic efficacy. The possibility that this multiple RCC can be a part of the abnormalities occurring in the Von Hippel-Lindau syndrome does not change the surgical approach, being the RCC the worst prognostic factor of the syndrome.

[Retroextraperitoneal laparoscopic nephrectomy]. / Nefrectomia laparoscopica per via retroextraperitoneale.

The authors describe a new technique of laparoscopic nephrectomy; the retroextraperitoneal approach has been successfully performed in 4 patients with the following indications: 2 non functioning hydronephrotic kidneys, 2 atrophic chronic pyelonephritic kidneys. The patient was put in a proneoblique position after the retrograde placement of a ureteral catheter up to the renal pelvis, through which the contrast medium was injected. The Veress needle is inserted under fluoroscopic guidance into the perirenal fatty space which was insufflated with CO2. One 12 mm and three 10 mm Trocars were inserted into the cavity created by gas in the trapezoid area whose boundaries are: the 12th rib, the iliac crest, the posterior axillary line and the sacrospinalis muscle. The kidney was progressively dissected free with the traditional laparoscopic instruments (forceps and scissors). The artery has always been closed with clips. In two patients the vein has been stapled and cut with EndoGIA. After the section of the clipped ureter the kidney was removed en block by pulling it out through the 20 mm Kleiber Trocar in two cases and in the other two cases by extending to a length of 4 cm the port of one Trocar. The average total operating time was 4.35 hours and blood loss < 200 cc. The patients were all discharged on the fourth postoperative day. The advantages of the retroextraperitoneal approach with respect to open surgery are synthetically the following: a less traumatic and a more accurate dissection almost always bloodless; a shorter hospitalization period; an almost painless postoperative course.(ABSTRACT TRUNCATED AT 250 WORDS)

[Ligation of the internal spermatic vein through 2 laparoscopic ports]. / La legatura della vena spermatica interna attraveso due porte laparoscopiche.

Thirty-three two port laparoscopic internal spermatic vein ligations have been performed in 31 patients in our Department. The procedure carried out through two 10 mm ports in a mean time of 25 minutes decreases both the invasivity of intervention and the costs when reusable instruments are used. The technique is feasible with an operative laparoscope (working channel diameter 4 mm) through which a grasp can be maneuvered. The two port procedure is as safe as the three port procedures. Preliminary follow up indicated only one recurrence of varicocele (4%). Out of the 19 patients treated for male subfertility who have at least a 6 month follow up, eleven reported an improvement in seminal quality. All the patients but one were discharged on the first postoperative day. Laparoscopic internal spermatic vein ligation provides a real alternative to different surgical techniques decreasing postoperative pain and shortening period of convalescence with immediate return to full activity. The advantages of laparoscopic internal spermatic vein ligation are increased with the two port procedure.

[Lymphoma of the prostate: case reports and subject review]. / Il linfoma della prostata: contributo clinico e revisione dell'argomento.

Malignant lymphomas involving the prostate are rare whether as primary lymphoma or as secondary to generalized disease. Middle age, histotype prevalently non Hodgkin, intermediate and high grade of malignancy, symptoms of bladder outflow obstruction, diagnosis generally made after histological examination, severe prognosis are the most important features that result from literature review. The evaluation of therapeutic treatments is difficult as most reports do not include a sufficient number of cases. The Authors presenting two cases of lymphoma of the prostate point out the usefulness of radiotherapy since the prostate is usually a bulky seat of disease and suggest the combination with multiple drug chemotherapy for intermediate and high grade of malignancy and in advanced stages. The authors suggest that prognosis depends on histotype rather than on prostatic involvement of disease.

[Bladder irrigation with aluminum solution for the control of massive hematuria]. / Irrigazione vescicale con soluzione di alluminio per il controllo di ematurie massive.

The massive bladder hemorrhage is a serious condition which implies important difficulties of treatment. Nine cases are presented: the continuous intravesical irrigation with 1% alluminium potassium sulphate in sterile distilled water was used, using continuous intravesical lavage with a double channel catheter. The haematuria was caused by radiation cystitis in 7 patients, vesical tumors in 2 patients. In every case there was a complete control of the hemorrhage in 12-72 hours with few immediate side effects, controlled in most cases with antispasmodics. This solution is economical, easy to prepare, simple to use and effective in the treatment of severe bladder hemorrhage.
