[TVA and TOA. New adjustable mesh for the treatment of female stress incontinence. Preliminaries results]. / TVA y TOA. Nuevas mallas ajustables de tensión en el tratamiento de la incontinencia urinaria de esfuerzo. Resultados preliminares.

OBJECTIVES: Evaluation of a new mesh for incontinence (TVA/TOA) which enables the degree of tension applied during surgery to be readjusted at the post-operative stage. PATIENTS AND METHOD: 62 patients treated with the TVA mesh and monitored over a 14-month period (SD 7.8, range 6-38). In 33 patients (53%) some other pelvic prolapse was corrected. Evaluation was carried out by clinical report, examination of bladder full of 250 saline solution, flowmetry and urinary residue. 40 patients filled in 4 quality of life questionnaires (QoL; ICIQ-SF; PGI-S; PGI-I). RESULTS: 42 patients were found to be objectively continent in the post-operative evaluation. Of these, it was necessary to reduce tension in 7 cases (11%) due to urinary obstruction (flow < 10 ml/sec and/or residue). The tension of the mesh was tightened in 20 patients (32%) due to continue with a certain degree of incontinence. All patients were discharged as continent and with no residue. In the last revision, 58 patients (93%) proved to be objectively continent and 4 (6.5%) showed a notable improvement in their incontinence. The Q(MAX) is 19.8 ml/sec (SD 9.8). The mictional urgency had disappeared or improved in 32 of the patients who had this prior to operation (76%) and had appeared in 3 of the patients who didn't (15%). The clinical report showed a high level of consensus with the ICIQ-SF survey (Kappa = 0.89) regarding stress incontinence, diminishing clearly (Kappa= 0.13) when urge incontinence was taken into account. 34 (85%) patients scored over 95 out of 110 in the QoL. 30 (75%) scored less than 6 in ICIQ-SF. 32 (80%) showed a perception of normality and 4 (10%) slight illness in the PGI-S. In the PGI-I 29 (72.5%) were much better and 11 (27.5%) quite a lot better. A relation exists between urgency and dismissed quality of life. CONCLUSION: With the TVA (trans-vaginal adjustable) mesh it is possible to adjust the tension originally applied during surgery at the post-operative stage, so that any defects or excesses can be corrected.

[Urodynamics of enterocystoplasty and continent diversions]. / Urodinámica de la enterocistoplastia y derivaciones continentes.

OBJECTIVE: To describe the filling and voiding urinary dynamics of enterocystoplasty and continent urinary diversion. METHODS: The different behaviour of the tubularized and detubularized intestinal segments and the different sphincteric lesions related with various surgical techniques are described. The possible causes of incontinence are discussed and the literature briefly reviewed. RESULTS/CONCLUSIONS: We underscore the importance of detubularizing the intestinal segment and preserving the sphincteric system as far as possible. Furthermore, voiding using abdominal pressure may cause post void residual urine, dilatation of the neobladder and renal changes. If warranted, self-catheterization should be performed.

[Histologic regression of localized prostatic tumor with neoadjuvant hormonal therapy]. / Desaparición histológica del tumor prostático localizado con hormonoterapia neoadyuvante.

OBJECTIVES: To determine the usefulness of preoperative hormone therapy in patients with organ-confined prostatic carcinoma undergoing radical prostatectomy. METHODS: 7 patients with localized prostatic carcinoma are presented. All patients were submitted to radical prostatectomy; 4 had been randomly selected for preoperative hormone therapy. RESULTS: Histological examination showed no nodal involvement in all cases. The tumor could not be identified (Po) in two of the four patients who received hormone therapy. The other two patients were staged down; the Gleason score remained unchanged in one and increased in the other. The patients who did not receive preoperative hormone therapy showed concordant clinical and pathological stages, except one in whom infiltration of the prostatic capsule was observed. No difference was found concerning the facility in performing surgery between the treated and untreated patients. CONCLUSIONS: Hormonal deprivation eliminated the tumor burden in two cases that might have been completely hormone sensitive, with no correlation in the pretreatment histological grade. Clinical downstaging is achieved by this treatment modality. However, further studies in larger series comparing the percentages of downstaging, histological downgrading, absence of tumor cells in the surgical specimen and impact on survivorship are warranted.

[Renal and urinary tract leishmaniasis. A disease to keep in mind]. / Leishmaniasis renal y vías urinarias. Patología a tener en cuenta.

Report of a case of renal and urinary tract leishmaniasis in a 61-year old male patient. The ureteral lesion responded favourably to treatment, unlike the renal one which required conservative surgery. Review of the literature stressing the fact that no other case has been found of kidney and urinary tract involvement. It is concluded that in the future, at least in those areas with a high prevalence of leishmaniasis, this condition should be taken into account as differential diagnosis when facing a toxic picture with renal involvement of the calyceal ecstasies type.

[Primary amyloidosis in the bladder: diagnostic and therapeutic update]. / Amiloidosis primaria de localización vesical: actualización diagnóstica y terapéutica.

We describe an additional case of primary amyloidosis of the bladder whose form of presentation warranted a differential diagnosis from carcinoma of the bladder. The diagnosis was made on the histological findings and the immunohistochemical analyses revealed amyloid fibrils that reacted against the light chain lambda antiserum. The treatment of choice was TUR, which resolves the condition in most of the cases. Conservative surgery, however, does not prevent new deposits and undetected residual lesions may persist, which may warrant other complementary procedures in these patients. After the diagnosis has been made, it is important to discard systemic amyloidosis.

[New location of aggressive angiomyxoma: the bladder]. / Nueva localización del angiomixoma agresivo: la vejiga.

Presentation of one case of aggressive angiomyxoma with vesical location in a 31-year-old female patient who underwent partial surgery, and who 8 years later remains disease-free. Emphasis is made on the low frequency of these tumours, of which only 26 cases are described in the international literature. All these cases have been located in soft areas of the pelvis and the perineum, with the exception of the one presented here, the first one with a vesical location. Clinical behaviour is characterized by the absence of metastasis and a great tendency to local relapse, 70% of cases reported.
