ABSTRACT

OBJECTIVE: To investigate what changes are endoscopically evident after glycosaminoglycans (GAGs) therapy by hyaluronic acid (HA) and chondroitin sulphate (CS) (Ialuril®) in female patients affected by bladder pain syndrome(BPS)/ interstitial cystitis (IC) or recurrent urinary tract infections (rUTIs). PATIENTS AND METHODS: 21 female patients over 18 years affected by rUTIs or BPS/IC received intravesical instillation of HA and CS (4 weekly instillations followed by 2 instillations every 2 weeks and 2 instillation monthly). Post-treatment evaluation included cystoscopy and patient assessment of improvement in symptoms and satisfaction on a visual analogue scale (VAS) from 0 to 10. RESULTS: The post-treatment endoscopy showed a positive effect on bladder mucosa morphology. In 2 cases, treatment did not change endoscopic findings and clinical symptoms. In the other patients, when macroscopic features of the bladder mucosa normalized, the clinical picture improved. CONCLUSIONS: GAGs therapy by HA and CS (Ialuril) improves the morphology of bladder mucosa in patients with rUTI or BPS/IC.

ABSTRACT

BACKGROUND: Although botulinum toxin (BoNT/A) injected into the detrusor muscle improves overactive bladder symptoms in patients with neurogenic detrusor overactivity, how it does so remains unclear. In this study, we investigated whether BoNT/A improves detrusor overactivity by modulating bladder afferent activity. METHODS: To do so, during urodynamic assessment, we tested the soleus muscle Hoffmann (H) reflex during bladder filling before and after intradetrusor BoNT/A in patients with Parkinson's disease (PD) and in patients with complete chronic spinal cord lesion (SCI) and detrusor overactivity refractory to conventional therapy. Healthy subjects underwent H reflex studies during urodynamic assessment and acted as controls. RESULTS: Our findings show that BoNT/A injected into the detrusor muscle effectively reduces clinical overactive bladder symptoms in patients with PD and SCI. In healthy subjects and patients with PD, bladder filling [at maximum cystometric capacity, (MCC)] significantly decreased the H reflex size, whereas in patients with SCI, it slightly facilitated the H reflex size. At MCC, in patients with PD, BoNT/A significantly reduced the expected H reflex inhibition, whereas in those with SCI, BoNT/A turned the H reflex facilitation at maximum bladder filling into a slight inhibition. CONCLUSIONS: These findings show that BoNT/A injected into the detrusor muscle in patients with PD and SCI modulates bladder afferent activity. Modulation of bladder afferents possibly explains why BoNT/A improves detrusor overactivity.

ABSTRACT

The increase of the prevalence of pelvic organ prolapse (POP) and urinary incontinence (UI), associated to changes in longevity, population demographics, and lifestyle expectation, is leading to a different set of urogynecological surgical challenges for 21st century women The objective of this review is to determine the characteristics and the effects of the different surgical technique in the management of POP. Here, we reviewed traditional techniques as well as we are going to take in consideration the introduction of several new procedures involving the use of different meshes or grafts, with or without introducer kits. Finally the laparoscopic approaches and the rapidly evolving robotic surgery will be discussed. Waiting for studies with high level of evidence, due to the plethora of techniques, mesh or graft material, absorbable (synthetic and biological) and non-absorbable, at present, there seems to be no final evidences about the best management.

ABSTRACT

AIM: The aim of this study was to review recent literature on mini-invasive surgical technique for the treatment of female stress urinary incontinence (SUI). Surgical aspects, intraoperative and perioperative complications and objective and subjective outcomes were analyzed and compared. METHODS: The PubMed databank from 2000 to February 2007 was searched for original prospective and randomized studies in English, on surgical treatment of female SUI, which avoided a laparotomic access to the female pelvis. Studies had to investigate at least 40 women with a minimum follow-up of 12 months. RESULTS: A total of 38 prospective studies were found: 27 of them were on mid-urethral slings; 8 assessed urethral injections; and 3 radiofrequency treatment. Fifteen studies were randomized. Follow-ups ranged from 12 to 60 months, except for sexual function which had a 6-month follow-up. Ten out of 38 studies assessed patients who did not refer pelvic organ prolapse or detrusor overactivity and had not undergone any previous anti-incontinence procedure. CONCLUSION: Mid-urethral slings showed good outcomes and are safe and brief to perform and have a relatively short learning curve. Urethral injections showed discouraging results, as they have poor outcomes and repetitive treatments are frequently necessary. Injections can be used in women with contraindications to major surgical procedures, with intrinsic sphincter deficiency as the main cause of incontinence. Radiofrequency showed worse results than mid-urethral slings and is a valuable choice in women who refuse more invasive procedures. The development of studies with longer follow-ups on mini-invasive surgical techniques are encouraged.

ABSTRACT

In recent years stone disease has become more widespread in developed countries. At present the prevalence is 5.2 and 15% of men and 6% of women are affected. The increase is linked to changes in lifestyle, eating patterns and obesity which has become very common. The 'metabolic syndrome' includes all the diseases, e.g. hypertension, lipid imbalances, type 2 diabetes mellitus, gout and cardiovascular disease, which are concomitant in the majority of stone formers. Dietary patterns, besides leading to stone formation, also determine stone chemistry. With a diet that is rich in oxalates, calcium oxalate will constitute 75% of stones, struvite 10-20%, uric acid 5-6% and cystine 1%. As approximately 50% of patients with stones suffer recurrences, metabolic and/or pharmacological prophylaxis is recommended.

ABSTRACT

The preservation of NANC nerve fibers (producing nitric oxide, NO) is necessary for erection recovery after retropubic radical prostatectomy (RRP). Yet, it is impossible to establish when and if a patient will recover erections; therefore, we investigate the prognostic value of cavernous blood NO levels on this parameter. Nerve-sparing RRP was performed on 14 patients for localized prostate cancer. We evaluated all patients 3 months after surgery by IIEF score: no patients had erections. A cavernous blood sample was also taken to determine NO levels (as nitrite). Patients were evaluated again 18 months after surgery. In six cases, erectile function was compromised, whereas in seven cases, potency was restored. Statistical analysis showed a relationship between nitrite levels in cavernous blood 3 months after surgery and the recovery or erectile function at 18 months. We propose that cavernous NO blood levels are a prognostic index of erection recovery.

ABSTRACT

AIM: Current pharmacologic treatment of detrusor overactivity relies on anticholinergic drugs. However, they often have untolerable side effects so that they are administered in doses insufficient to restore urinary continence. Recently, intravesical instillations and injections into the detrusor muscle of new pharmacological agents have been developed. The present study report our own experience in the treatment of detrusor overactivity with intravesical administrations of vanilloid agents and with botulinum-A toxin injections into the detrusor muscle in a group of spinal cord injured patients. In particular, we compared the clinical and urodynamic effects of the 2 drugs in an attempt to find a new and valid therapeutic option in those cases unresponsive to conventional treatment. METHODS: Seventy-five patients with spinal cord injury and refractory detrusor overactivity were included in the study: 35 patients received repeated intravesical instillations of resiniferatoxin (RTX) dissolved in normal saline; 40 patients received repeated injections of 300 units botulinum A-toxin diluted in 30 ml normal saline. Clinical assessment and urodynamics were performed at baseline and 6, 12 and 24 months after treatment. RESULTS: With both treatments there was a significant reduction in mean catheterization and episodes of incontinence and a significant increase in mean first involuntary detrusor contraction and in mean maximum bladder capacity at 6, 12 and 24 months after therapy. We did not detect any local side effects with either treatment. Botulinum-A toxin significantly reduced also the maximum pressure of uninhibited detrusor contractions more than RTX at all follow-up time points. CONCLUSION: In patients with spinal cord injury and refractory detrusor overactivity intravesical RTX and botulinum-A toxin injections into the detrusor muscle provided beneficial clinical and urodynamic results with reduction of detrusor overactivity and restoration of urinary continence in most patients. Botulinum-A toxin injection provided better clinical and urodynamic benefits than intravesical RTX.

ABSTRACT

We report our experience with four-corner colposuspension and the long-term functional and objective results. Thirty-seven women aged 42-74 affected by cystocele, associated with stress incontinence in 27, underwent four-corner colposuspension, combined with posterior colpoperineoplasty in 5 and vaginal wall sling in 5. Preoperative work-up included clinical examination, a symptoms questionnaire, transrectal dynamic ultrasonography and a urodynamic test. The mean follow-up to date is 62 months (range 36-83). Check-ups included a clinical examination, responses to a questionnaire on symptoms, uroflowmetry, transrectal ultrasound, and a urodynamic test in 25. All patients underwent four-corner colposuspension, together with vaginal wall sling in 5 with severe incontinence and colpoperineoplasty in another 5 with symptomatic rectoceles. There were no major complications. The urethrocele was stably corrected in all. No relapses occurred in 19 patients with grades I-II cystocele preoperatively. Various forms of prolapse recurred in 12/18 patients with grade III cystocele. Incontinence was successfully resolved in 23/27 patients (85%). Instability persisted in 8/14 patients. Obstruction persisted in 6 patients with prolapse recurrence. The ideal candidate for four-corner suspension is a patient with moderate cystocele and no signs of uterine prolapse who may, or may not, be incontinent.

ABSTRACT

PURPOSE: We evaluated the incidence of peritumoral satellite lesions in nephron sparing surgery and examined whether these findings have a negative effect on cancer specific survival and on the percent of local recurrence. MATERIALS AND METHODS: We performed nephron sparing surgery in 63 patients with kidney cancer, including 53 elective (group 1) and 10 imperative (group 2) operations. In all cases we removed 10 mm. of apparently healthy peritumoral parenchyma with the tumor. This tissue was subsequently examined by an anatomical pathologist to identify any satellite lesions. RESULTS: Four satellite lesions were identified, including 3 in group 1 and 1 in group 2, at a mean of 5.3 mm. from the primary lesion. None of the patients in either group had local recurrence at followup. Cancer specific survival was 96.3% in group 1 (mean followup 61 months) and 58% in group 2 (mean followup 39 months). It was not influenced by the presence of satellite micro-lesions. CONCLUSIONS: Despite common perplexities concerning the risk of multifocality in renal cell carcinoma we believe that the nephron sparing procedure in select patients is as effective as radical surgery. Based on our experience the surgical safety margin must be at least 10 mm. of macroscopically healthy, peritumoral tissue.

ABSTRACT

This work aimed to study the activities of the glyoxalase system enzymes (glyoxalase I (GI) and glyoxalase II (GII) and their gene expression in human bladder carcinomas compared with the corresponding normal mucosa. Samples of these tissues were collected from 26 patients with superficial (SBC) or invasive bladder cancer (IBC) and used to evaluate enzyme activity and gene expression by northern blot analysis. In keeping with the electrophoretic pattern and the expression level of the respective genes, GI activity significantly increased in SBC samples, while it remained unchanged in IBC samples compared with the normal mucosa. In contrast, GII showed a higher activity in the tumour (either SBC or IBC samples) versus normal tissues. These results confirm the role of the glyoxalases in detoxifying cytotoxic methylglyoxal (MG) in bladder cancer. The differing levels of GI activity level and gene expression of GI between the SBC and IBC samples could help in their differential diagnosis.

ABSTRACT

A prospective analysis of 166 women with genuine stress incontinence was performed comparing Valsalva leak-point pressure (VLPP) and maximum urethral closure pressure (MUCP) with age, previous urogynecologic surgery and/or hysterectomy, poor urethral mobility, weight, menopause and vaginal deliveries, to find correlations with intrinsic sphincter deficiency (ISD). Cut-off value for VLPP were 60 cmH2O and for MUCP 30 cmH2O. MUCP < or = 30 cmH2O identifies a group of patients with more severe incontinence, a shorter urethral functional length (UFL) (P = 0.02), more previous urogynecologic operations and the menopause (P = 0.004 and P = 0.000), and older age (P = 0.000). VLPP < or = 60 cmH2O identifies a group of patients with more severe incontinence, a shorter UFL (P = 0.005), more previous urogynecologic surgery (P=0.006) and poorer urethral mobility (P = 0.004). As these two tests measure different components of urethral functions we can hypothesize that they detect different pathogenic processes contributing to ISD. When one or both tests is abnormal incontinence is more severe and the incidence of poor prognostic factors is increased.

ABSTRACT

During the last years important changes in the management of the patients with erectile dysfunction have been verified. Psychologist, neuro-physiologist and bioengineers have given a valuable help in this field. Implant surgery represents, to our notice, the curative more acceptable choice for patient and the partner, since the results are excellent and the materials used extremely manageable. In each case the degree of satisfaction of the patient remains the only legitimate indicator currently for establish the effectiveness of the therapy.

ABSTRACT

OBJECTIVE: To establish who the best candidates for corporoplasty are. The standard guidelines include patients with partial erections, and/or recurvature preventing normal and satisfying intercourse. In our unit we prefer to implant prostheses even in patients with slight erectile dysfunction, therefore patients with full erections routinely undergo corporoplasty. MATERIALS AND METHODS: We report our experience with corporoplasty using a vein patch graft after plaque incision or excision in 12 patients affected by Peyronie's disease. RESULTS: The operation is easy to perform. Recovery of normal spontaneous erectile activity was observed in 10/12 (83%) patients at a mean of 1 month postoperatively. The results of checkups with Rigiscan and EchocolorDoppler have confirmed the stability of the graft and recovery of potency. DISCUSSION: Autologous material is easy to harvest and it is elastic enough to support traction during erection. The patch can be modelled to fashion patches in any shape required. The risk of scar shrinkage, with the consequent onset of recurvature, is lower than with other materials such as Gore-tex or Derma. Corporoplasty ensured rapid rehabilitation of sexual functions in all patients. We do not usually perform the Nesbit procedure as shortening of the penis (which is characteristic of Peyronie's disease) would, in most patients, be accentuated by albuginea plication.

ABSTRACT

PURPOSE: A proportion of patients with detrusor hyperreflexia who are unresponsive to oral oxybutynin often benefit from intravesical oxybutynin instillation. To our knowledge the precise mode of action of this method is obscure. MATERIALS AND METHODS: In 12 patients with detrusor hyperreflexia who were previously unresponsive to oral and intravesical passive diffusion of 5 mg. oxybutynin we administered 5 mg. oxybutynin orally as well as increased doses of 15 mg. oxybutynin intravesically with passive diffusion and with 15 mA. associated electric current. Each administration mode per patient was associated with an 8-hour urodynamic monitoring session during which oxybutynin and N-desethyl oxybutynin plasma levels, and intravesical oxybutynin uptake were measured. RESULTS: A dose of 5 mg. oxybutynin orally induced no urodynamic improvement with an area under the plasma concentration time curve of combined N-desethyl oxybutynin plus oxybutynin of 16,297 ng./8 hours and an area under the curve ratio of N-desethyl oxybutynin-to-oxybutynin of 11:1. Passive diffusion oxybutynin resulted in 12 mg. oxybutynin intravesical uptake and significant improvement in 3 of 8 urodynamic measurements, although the area under the curve of combined N-desethyl oxybutynin plus oxybutynin was only 2,123 ng./8 hours and the N-desethyl oxybutynin-to-oxybutynin ratio was 1.1:1.0. Electromotive administration of oxybutynin resulted in almost complete intravesical uptake of the 15 mg. dose, significant improvement in all 8 urodynamic measurements and an increased oxybutynin level versus oral and passive diffusion, although the area under the curve of combined N-desethyl oxybutynin plus oxybutynin was 4,574 ng./8 hours and the N-desethyl oxybutynin-to-oxybutynin ratio was inverted at 1.0:1.4. The oral dose of 5 mg. oxybutynin caused anticholinergic side effects in 8 of the 12 patients. Neither intravesical passive diffusion nor electromotive administration caused side effects with an uptake of 12 and 15 mg., respectively. CONCLUSIONS: A large proportion of intravesical oxybutynin is sequestered, probably in the urothelium. Intravesical oxybutynin administration confers therapeutic benefits via localized direct action within the bladder wall.

ABSTRACT

PURPOSE: We compared the safety and patient acceptance of a conventional Nélaton and a prelubricated nonhydrophilic catheter in 18 spinal cord injured patients on intermittent catheterization. MATERIALS AND METHODS: In a prospective crossover study each catheter was used for 7 weeks and the initial course was randomized. Urinalysis and urine culture were performed at 2, 4 and 7 weeks. Urethral trauma was evaluated by urethral cell count on the surface of each catheter used on the last day of each study period. Patient satisfaction was assessed at the end of the study by a questionnaire using multiple visual analog scales. RESULTS: Urinary tract infection was identified in 12 and 4 patients on a Nélaton and a prelubricated nonhydrophilic catheter (p = 0.03), while asymptomatic bacteruria was identified in 18 and 8 (p = 0.0244), respectively. The mean urethral cell count plus or minus standard deviation on the catheter surface was 6.7 +/- 2.8 x 10(4) and 15.1 +/- 8.9 x 10(4) for the prelubricated nonhydrophilic and the Néelaton catheter, respectively (p = 0.01). The prelubricated nonhydrophilic catheter resulted in a better mean satisfaction score than the Nélaton catheter (2.33 +/- 1.06 versus 4.72 +/- 2.13, p = 0.022). Urethral bleeding was reported in 2 patients during the study period while using the Nélaton catheter. CONCLUSIONS: The prelubricated nonhydrophilic catheter is a safe, effective and comfortable option in spinal cord injured patients on intermittent self-catheterization.

ABSTRACT

OBJECTIVE: This study reports our experience with a ureteroileal reimplantation technique based on the Leadbetter-Clarke method, which is used for orthotopic neo-bladders, constructed preferably with the Camey II technique. METHODS: We carried out 114 ureteroileal reimplantations using this technique in 58 patients undergoing radical cystectomy and orthotopic neobladder reconstruction. The incidence of neobladder-ureteral stenosis and reflux were analyzed during the follow-up. RESULTS: During the mean follow-up of 31 months, the incidence of stenosis was 2.6% (3 ureteroileal implants, including 1 case of neoplastic stenosis). The incidence of slight-to-moderate reflux was 9.6% but did not cause any deterioration in renal function or an increased incidence of reflux-related pyelonephritis. CONCLUSION: This technique provided good functional results and a low incidence of complications, and may be recommended as a valid alternative to standard methods of creating ureterovesical anastomosis.

ABSTRACT

BACKGROUND AND OBJECTIVES: We present the long-term functional results of a new technique for bladder substitution after cystectomy for bladder cancer in women. METHODS: Between 1991 and 1995, 10 women underwent radical cystectomy for bladder cancer with a new technique. We created a detubularized rectosigmoid neobladder associated with either a terminal colostomy or intrasphincteric perineal colostomy section (Heitz-Boyer-Hovelacque). We evaluated neobladder functioning over almost 5 years by means of urodynamic studies, ultrasound scans, urograms and pouchgrams, and renal function tests. RESULTS: Neobladder function was excellent in all patients, with good diurnal and nocturnal urinary continence, voiding patterns, and preservation of the upper urinary tract. CONCLUSIONS: This new technique, which is a modification of the standard rectal or rectosigmoid neobladder technique, is a valid alternative to the ortothopic neobladder in women, with good functional results.

ABSTRACT

Both prophylaxis and stone-free status after ESWL are most important goals in treating urinary stone disease, because his high social cost. In order to this situation, we matched two homogeneous groups of patients that underwent ESWL because renal stones: during a one year follow-up with several US controls, daily 1.5 litres of low mineral content water was drank by I group patients; vice versa, daily 3 litres (1st ten days) and afterwards 2 litres of Rocchetta low mineral content water was drank by II group patients. This last kind of approach led to a significant improvement in stone fragments elimination time, in inferior calix stone cure and in stone recurrences rate. So we conclude that hyperhydration using right low mineral content water, is a simple and cheap way to improve both treatment and prophylaxis of urinary stones.

ABSTRACT

PURPOSE: We assessed the efficacy of voiding and bladder biofeedback for achieving perineal synergy and curing symptoms in children with detrusor-sphincter dyssynergia MATERIALS AND METHODS: A total of 16 boys and 27 girls 4 to 14 years old with detrusor-sphincter dyssynergia diagnosed by uroflowmetry and electromyography underwent biweekly voiding biofeedback therapy consisting of perineal floor electromyography during uroflowmetry. The 6 patients with enuresis and an unstable bladder also underwent bladder biofeedback training during cystometry. Biofeedback continued until detrusor-sphincter dyssynergia resolved. Followup consisted of electromyography and uroflowmetry 1 month after completing biofeedback training, and telephone interviews after 2 and 4 years. RESULTS: Biofeedback resolved detrusor-sphincter dyssynergia in all children, although the condition disappeared significantly sooner in girls (p <0.02). Secondary enuresis disappeared significantly earlier than primary enuresis (p <0.0001). The 2-year success rate of 87.18% for enuresis decreased to 80% at the 4-year followup. CONCLUSIONS: Voiding and bladder biofeedback achieves perineal synergy and cures symptoms in children with detrusor-sphincter dyssynergia
