Testicular sperm retrieval and intra cytoplasmic sperm injection provide favorable outcome in spinal cord injury patients, failing conservative reproductive treatment.

STUDY DESIGN: Retrospective cohort analysis. OBJECTIVES: The objective of this study was to determine the in vitro fertilization (IVF) outcome after testicular sperm extraction (TESE) in a group of spinal cord injury (SCI) male patients not compatible with conservative fertility treatment. SETTING: University-affiliated medical center. METHODS: Thirty two SCI patients (C2 to L2) were referred to IVF after repeated trials of electroejaculation (EEJ) or penile vibratory stimulation (PVS), and full andrological evaluation. Testicular sperm aspiration (TESA) was the method of choice for sperm extraction. Open TESE was performed only after a negative TESA attempt. Clinical pregnancy and live birth rates were determined. RESULTS: A total of 106 testicular procedures were performed. Sperm was found in 95 cycles (89.6%). The average metaphase II (MII) oocyte number was 11.0±4.2, an average of 5.1±2.3 oocytes became normally fertilized after Intra Cytoplasmic Sperm Injection (ICSI) (fertilization rate 57.1%). On average, 2.7±1.2 embryos were replaced. The clinical pregnancy rate was 32/106 (30.2%) per cycle and 19/32 (59.3%) per couple. Live birth rate was 62.5% (20/32). CONCLUSIONS: TESA/E and IVF can provide excellent prognosis for SCI patients that cannot be treated by EEJ or PVS.

IVF outcome with cryopreserved testicular sperm.

The introduction of intracytoplasmic sperm injection and the use of spermatozoa extracted from the testicles have changed the option for conception for azoospermic patients. The purpose of the present study was to evaluate the IVF outcome after using cryopreserved testicular sperm samples in comparison with fresh ones. A total of 667 in vitro fertilisation cycles with fresh or cryopreserved testicular sperm obtained by an open biopsy and testicular needle aspiration were evaluated. Sperm motility was present in 70.9% of the cycles in Group-I, 77.8% cycles in Group-II and in 83.3% In Group-III (NS). The fertilisation rates were similar in the three study groups (50%, 48.6% and 54.8% respectively). The pregnancy rates were 26.7%, 22.2% and 16.3% respectively (NS). The delivery rate, however, was significantly lower in Group-III (4.1%) than in Group-I and -II (18.4% and 15.9%, respectively, P < 0.05). The IVF results after use of cryopreserved testicular sperm are comparable with those obtained with the fresh specimens. Lack of sperm motility before cryopreservation does not exclude favourable outcome and therefore testicular sperm freezing is feasible whenever there are enough sperm cells in the extracted testicular tissue.

New prospective for non-invasive detection, grading, size evaluation, and tumor location of prostate cancer.

BACKGROUND: PSA blood test and other present screening tools fail to provide the required sensitivity and specificity and, at early stages, lack correlation with tumor grade, volume, and location. Thus alternative approaches are highly desired. We present and assess a novel method for PCa detection, grading, volume evaluation and tumor location, based on non-invasive zinc concentration mapping in the gland by means of a dedicated rectal probe. METHODS: Zinc-concentration values measured in histologically examined tissue fragments from needle biopsy of 598 patients were analyzed. They were used to generate computer simulated zinc-concentration maps, further analyzed with image-processing tools. The tumor detection performances versus Gleason grade were assessed. RESULTS: A significant increase of zinc depletion with increasing Gleason pattern (grade) classification was established. Tumor detection performance in zinc-concentration maps progressively improves with the cancer's first component score. Reliable information on the location, size and Gleason-grade combination of the lesion can be extracted for clinically relevant volumes. CONCLUSIONS: Zinc depletion in the prostate peripheral zone is the basis for a novel, non-invasive PCa detection, localization, volume evaluation and grading method. Its realization and application as a pre-biopsy and pre-treatment examination, or a follow-up tool, relies on the development of a dedicated transrectal probe. It should have significant impact on biopsy effectiveness, point at a possible extraprostatic extension and provide critical data for focal treatment. The information on tumor grade and distribution may have an important impact on disease management.

Does age at orchidopexy impact on the results of testicular sperm extraction?

The aim of this study was to evaluate the affect of age at the time of orchidopexy on testicular sperm extraction (TESE) results among patients with a history of cryptorchidism and azoospermia. This retrospective study compared TESE results for couples undergoing IVF treatment, among two groups of patients. Group A included patients who underwent orchidopexy at age 10 and younger, and group B included patients who had the procedure above the age of 10. A total of 42 patients were included in the study. Forty patients had bilateral cryptorchidism and two had unilateral. The overall rate of sperm recovery was 59.5%. No differences were found in the sperm retrieval, fertilization, implantation, pregnancy, or live birth rates between the groups. The results suggest that age at orchidopexy, either at 10 years of age or younger or above 10 years of age, was not a predictive factor for successful TESE. Although bilateral cryptorchidism is usually considered a testicular secretory dysfunction, it was found that sperm retrieval attempts yielded spermatozoa in almost 60% of patients with azoospermia and a history of cryptorchidism.

Evaluating the cancer detection and grading potential of prostatic-zinc imaging: a simulation study.

The present work deals with the analysis of prostatic-zinc-concentration images. The goal is to evaluate potential clinically relevant information that can be extracted from such images. In the absence of experimental images, synthetic ones are produced from clinically measured zinc-concentration distributions in certified benign and cancerous tissue samples, classified by the lesion grade. We describe the method for producing the images and model the effect of counting statistics noise. We present in detail the image analysis, which is based on a combination of standard image processing and segmentation tools, optimized for this particular application. The information on lowest zinc value obtained from the image analysis is translated to clinical data such as tumour presence, location, size and grade. Their confidence is evaluated with the help of standard statistical tools such as receiver operating characteristic analysis. The present work predicts a potential for detecting small prostate-cancer lesions, of grade (4+3) and above, with very good specificity and sensitivity. The present analysis further provides data on the pixel size and image counting statistics requested from the trans-rectal probe that will record in vivo prostatic-zinc maps in patients.

IVF outcome in azoospermic cancer survivors.

OBJECTIVE: To assess clinical outcome among infertile couples treated by in vitro fertilization (IVF) and intra cytoplasmic sperm injection (ICSI) using testicular sperm from azoospermic cancer survivors. STUDY DESIGN: This clinical retrospective study included infertile couples treated in a single tertiary referral center between 1996 and 2013. All male partners were cancer survivors who were diagnosed with azoospermia due to previous gonadotoxic treatments and referred to testicular sperm extraction (TESE). Retrieved sperm was used for IVF-ICSI among patients' spouses. Sperm retrieval rate and IVF-ICSI outcome were evaluated. RESULTS: Sperm was successfully retrieved in 12 out of 36 patients (33.3%) on initial TESE, with an overall sperm retrieval rate of 38.6% (17 of 44). Female patients were 29.8±5.1 years old. The average number of retrieved oocytes was 14.0±4.0 per cycle, with clinical pregnancy and live birth rates per successful TESE of 64% (11 of 17) and 58.8% (10 of 17), respectively. Age, serum FSH, testicular volume and time from chemotherapy to TESE were not significantly different between patients with successful TESE to those without. Patients suffering from seminomas had significantly higher sperm retrieval rate, as compared to patients who had Hodgkin's lymphoma (P=0.024). CONCLUSIONS: Post-chemotherapy azoospermia can be successfully treated with TESE and ICSI, and should be offered to azoospermic cancer survivors who did not cryopreserve sperm prior to their gonadotoxic treatments.

Correlation between premature ejaculation and female vaginal penetration difficulties.

Male and female sexual dysfunctions encompass biological, psychological and interpersonal aspects. Premature ejaculation (PE) and female vaginal penetration difficulties (VPD) are problems that may concurrently impair the couple's sexual relationship. We have studied the correlation between PE and VPD in the female partner, in a cross-sectional study of 125 heterosexual couples (male age 35.01±10.63; female age 32.36±10.07). VPD included tampon insertion, gynecological examination, inserting self-finger or partner-finger and penile-vaginal intercourse. Female sexual function index (FSFI) and a validated PE questionnaire were used to measure the female sexual function and PE in their male partners. We found that female partners of men with anteportal ejaculation were found to experience significantly more VPDs, especially with regard to difficulties in penile penetration and tampon use. The intensity of pain in VPD was higher in females whose male partners presented anteportal ejaculation. No significant correlation was found between total male PE score and the total FSFI or separate domains of female sexual function. The results suggest that female VPD and male anteportal ejaculation are interrelated. Such severe couple sexual problems should be addressed in parallel. Further research is required to study the causation of PE and VPD.

Studies on sperm chromosomes in patients with severe male factor infertility undergoing assisted reproductive technology treatment.

The aim of the study was to determine the rate of chromosome abnormalities in testicular sperm after intracytoplasmic sperm injection due to severe male factor infertility. The study groups included patient with non-obstructive azoospermia (n=9), obstructive azoospermia (n=10), Klinefelter's syndrome (n=5) and normal controls (n=6, groups I-VI, respectively). The mean serum levels of FSH 17.5+/-8.2 (P<0.05), 3.5+/-2.6, 29.8+/-13.0 (P<0.05) and 3.1+/-0.4 mIU/ml, respectively. The rates of chromosome abnormalities were 19.6% (P<0.001), 8.2% (P<0.001), 6.3 and 1.6%, respectively. Chromosomes X and Y were significantly more involved in the aneuploidy than chromosome 18 in groups I and II. The present findings demonstrate a linkage between gonadal failure (high serum FSH levels) and sperm chromosome abnormalities. Our findings may explain the increased incidence of perinatal sex chromosome abnormalities found in severe male factor patients. Patients with non-mosaic Klinefelter's syndrome have comparable risk for sex chromosomes aneuploidy as the rest of the patients with azoospermia. Therefore, genetic screening during pregnancy or before embryo replacement should be carefully considered in severe male factor patient following in vitro fertilization (IVF).

In-vitro characterization of dihydrotestosterone-induced, epidermal growth factor-induced and basic fibroblastic growth factor-induced modifications in the growth dynamics of the human prostate-cancer cell-line lncap, du145 and pc3.

The influence of dihydrotestosterone (DHT), the epithelial growth factor (EGF) and the basic fibroblast growth factor (bFGF) was investigated on LNCaP, DU145 and PC3 cell growth, which represents the ratio between cell gain (cell proliferation) and cell loss (cell death). In the present study, cell growth was assessed by means of the computer-assisted microscope analysis of Feulgen-stained nuclei combined with the mathematical Delaunay triangulation and Voronoi paving techniques, which enabled the cell colony patterns, i.e. their density and level of organisation, to be determined. The results from a previous study (Janssen et al, Prostate, in press) combined with those of the present one show that DHT was found to activate proliferation of the LNCaP model, as evidenced by increase in size of colonies, increase in number of cells within colonies, increase in cell colony density and, accordingly, decrease in mean segment length value (which is the distance between adjacent cell nuclei). Using the same criteria, DHT was found inhibitory on growth of DU145 cell line, and devoid of significant effect on PC3 cell line. Basic FGF was found to be a powerful stimulator of growth of PC3 cell Line and to induce a weaker stimulation of DU145 cell line. On LNCaP cell line, it increased the size of colonies without increase of the number of cells per colony. This feature can be explained by a decrease in cell colony density. With respect to the same colonies, the proliferation index (percentage of cells in the S+G2 phases of the cell cycle) was found similar to that of the controls. This suggests that the increase in the size of the colonies is due to a difference of spreading of the cells on their supports. EGF had no significant effect on LNCaP and PC3 models, and was decreasing cell density of DU145 colonies.

Reconsidering the necessity of ipsilateral adrenalectomy during radical nephrectomy for renal cell carcinoma.

OBJECTIVES: Ipsilateral adrenalectomy is traditionally advocated as part of radical nephrectomy performed for renal cell carcinoma. The current study addresses the controversy of whether ipsilateral adrenalectomy should be performed routinely during radical nephrectomy. METHODS: A total of 225 patients were treated surgically for renal cell carcinoma over an 18-year period. Of these patients, 158 underwent nephrectomy and simultaneous ipsilateral adrenalectomy and the other 67 had sparing of the ipsilateral adrenal gland. A retrospective analysis of the medical records and assessment of the clinical and the pathologic data were performed. Rates of survival and progression were evaluated in a subgroup of 109 patients, further subdivided into 54 patients who underwent concomitant adrenalectomy and 55 patients with the ipsilateral adrenal preserved during surgery. RESULTS: Histopathologic abnormalities were detected in seven adrenal specimens (4.4%); however, only 3 patients (1.9%) had involvement of the adrenal by renal cell carcinoma. All cases of adrenal involvement were detected by the preoperative imaging modalities. Ipsilateral adrenalectomy did not improve the outcome in comparison to adrenal preservation. CONCLUSIONS: In view of the rarity of ipsilateral adrenal metastasis, the questionable prognostic merits of concomitant adrenalectomy, and the availability of accurate imaging modalities, we conclude that ipsilateral adrenalectomy is not necessary in the majority of the patients undergoing radical nephrectomy for renal cell carcinoma.

Sperm chromosome abnormalities in men with severe male factor infertility who are undergoing in vitro fertilization with intracytoplasmic sperm injection.

OBJECTIVE: To investigate the potential paternal contribution to the risk of fetal chromosomal anomalies after intracytoplasmic sperm injection (ICSI). DESIGN: Spermatozoa isolated from testicular tissue and ejaculated specimens of consenting patients undergoing testicular biopsy and ICSI were analyzed for chromosomes X, Y, and 18 by FISH. SETTING: Assisted reproductive technology program. PATIENT(S): Consenting patients undergoing testicular biopsy and ICSI, severe oligozoospermic patients, and normal fertile donors. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The rate of chromosome abnormalities in testicular sperm with regard to the type of azoospermia and ejaculated sperm compared to healthy men. RESULT(S): The mean serum levels of FSH in the groups with nonobstructive azoospermia (n = 9), obstructive azoospermia (n = 10), severe oligozoospermia (n = 9), and the normal donors (n = 6) were 17.5 +/- 8.2 (P<.05), 3.5 +/- 2.6, 14.6 +/- 3.5 (P<.05), and 3.1 +/- 0.4 IU/mL, respectively. The corresponding rates of sperm chromosome abnormalities among these groups were 19.6% (P<.001), 8.2% (P<.001), 13.0% (P<.001), and 1.6%, respectively. The corresponding rates of disomy among these groups were 7.8% (12 of 153 spermatozoa), 4.9% (18 of 367), 6.2% (109 of 1,751), and 1% (5 of 500 spermatozoa), respectively. Errors in chromosomes X and Y were significantly more common than in chromosome 18. CONCLUSION(S): The present findings demonstrate a linkage between gonadal failure (high serum FSH levels) and the occurrence of sperm chromosome aneuploidies. Our findings may explain the increased incidence of sex chromosome abnormalities found after IVF in the severe male factor patient population. Genetic screening during pregnancy or before embryo replacement should be considered carefully.

Sperm chromosome analysis and outcome of IVF in patients with non-mosaic Klinefelter's syndrome.

OBJECTIVE: The aim of the study was to determine the potential risk for fetal chromosomal anomalies in non-mosaic Klinefelter's syndrome patients undergoing IVF and intracytoplasmic sperm injection. DESIGN: Individually collected spermatozoa were isolated from wet testicular tissue preparations and fixed on glass slides using micromanipulation. Their nuclei were analyzed for chromosomes X, Y, and 18 by fluorescent in situ hybridization. SETTING: Assisted reproductive technology program. PATIENT(S): Consenting patients with non-mosaic Klinefelter's syndrome undergoing testicular biopsy and IVF (fresh specimens) or following such treatment (cryopreserved specimens). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The rates of numerical chromosome abnormalities for chromosomes X, Y, and 18 among spare testicular sperm and the pregnancy outcome following treatment. RESULT(S): Testicular sperm were found in 8 of 20 patients. Four couples became pregnant following embryo replacement. Sperm chromosomes were analyzed in five patients. One hundred and five sperm of 112 analyzed (93.7%) were normal with X to Y ratio of 50:55 (NS) respectively. Among the 112 sperm tested, seven (6.3%) demonstrated chromosomal abnormalities, of which five were related to the sex chromosomes and two to chromosome 18. One set of triplets, one set of twins, and two singletons (four males and three females) with normal karyotypes were born. CONCLUSION(S): Most of the testicular sperm retrieved from Klinefelter's syndrome patients demonstrates a normal pattern of sex chromosome segregation. Therefore, the risk of transmitting numerical sex chromosome abnormalities is relatively low and probably comparable with the rates found in other severe male factor infertility patient groups.

Outcome of in vitro fertilization and intracytoplasmic injection of epididymal and testicular sperm extracted from patients with obstructive and nonobstructive azoospermia.

OBJECTIVE: To evaluate IVF outcome after epididymal and testicular sperm retrieval in patients with obstructive or nonobstructive azoospermia. DESIGN: Retrospective clinical analysis. SETTING: Public university-affiliated IVF unit. PATIENT(S): One hundred twenty-three azoospermic patients (178 cycles). INTERVENTION(S): Sixty-three patients (103 cycles) with obstructive azoospermia (group 1) underwent either epididymal or testicular sperm retrieval, and 60 patients (75 cycles) with nonobstructive azoospermia (group 2) underwent testicular sperm retrieval combined with IVF treatment. Mature oocytes were fertilized using intracytoplasmic sperm injection. After sperm preparation, supernumerary spermatozoa were cryopreserved. MAIN OUTCOME MEASURE(S): Oocyte fertilization rate and clinical pregnancy rate (PR). RESULT(S): The oocyte fertilization rate was 48.4% (534/1,104) in group 1 and 41.5% (312/751) in group 2 (not significant [NS] difference). A total of 100 cycles (97.1%) and 62 cycles (82.7%) in the obstructive and nonobstructive groups, respectively, had embryos for replacement (NS difference). The clinical PRs per ET cycle were 24% (24/100) and 17.7% (11/62) in the two groups, respectively. Oocyte fertilization rates, when fresh (46.4%) or frozen-thawed (41.8%) spermatozoa were used, were not significantly different in the two groups. The PR when fresh sperm were used was 23.6% (30/127), versus 14.3% (5/35) when frozen sperm were used (NS difference). The PR for women aged < or = 35 years was similar to that for women >35 years of age (20.7% or 29/140 and 18.2% or 4/25, respectively). CONCLUSION(S): Epididymal and testicular sperm obtained in azoospermic patients can fertilize oocytes successfully and may lead to high fertilization rates and PRs. Freezing of these spermatozoa does not reduce the outcome of treatment significantly.

Difference in glycohistochemical lectin staining of collagen fibers in the corpora cavernosa of normal and impotent men.

The objectives of this study were to investigate the value of glycohistochemical staining with three lectin types specific to a particular glycan structure (Arachis hypogaea [PNA], Triticum vulgare [WGA], and concanavalin A [Con A]) as a method of defining possible changes in the collagen structure in the corpora cavernosa in potent and impotent men. The study group consisted of 4 normal potent men and 22 men with various etiologies of impotence. The quantitative histochemical measurements were performed by means of a cell image processor. Two variables for each of the three types of lectins were studied. These were the mean optical density (MOD), which relates to glycohistochemical staining intensity, and the labeling index (LI), which is positively related to the percentage of immunostaining. Only WGA staining made it possible to discriminate significantly between the normal and pathological groups under study. The two parameters (LI, MOD) were significantly higher in the case of WGA staining in the normal group (P = 0.004 and 0.013, respectively). In contrast, only the mean LI value, in the case of the psychogenic and venogenic patients, reached a level of statistical significance (P = 0.005 and 0.001, respectively), when it increased from PNA through WGA to Con A histochemical staining. The two variables (LI, MOD) changed markedly from PNA through WGA to Con A in the arteriogenic patients (P = 0.003 and P < 0.001, respectively). WGA is of diagnostic value in distinguishing between normal and abnormal collagen in the corpora cavernosa. The difference in the lectin staining of the other groups, particularly the arteriogenic group, may be attributed to alterations in the glycosylation of the procollagen that are probably due to changes in the partial pressure of oxygen (PO2) level, an important cofactor in normal glycosylation. WGA staining may therefore be used as a marker to distinguish true psychogenic patients from those with organic diseases. Moreover, it may be used as an additional parameter in selecting the best candidates for penile revascularization.

Radiofrequency interstitial tumor ablation (RITA) is a possible new modality for treatment of renal cancer: ex vivo and in vivo experience.

Small renal tumors are increasingly diagnosed and are frequently treated by nephron-sparing surgery. Tumors can be ablated by radiofrequency (RF) energy, which allows the operator to create very localized necrotic lesions. Radiofrequency interstitial tumor ablation (RITA) has been used in human kidneys in an ex vivo experiment to assess the necrotic lesions produced in a model close to physiologic conditions and then in three patients with localized renal cancer prior to radical nephrectomy. In the ex vivo model, four freshly removed kidneys were treated. Bipolar RF energy was delivered by a generator connected to two needles introduced parallel to each other into the renal parenchyma. A thermocouple was inserted between the two active electrodes. The renal artery at physiologic conditions was maintained at a constant temperature of perfusion of 37 degrees C by a computer-assisted Hot-line monitor. Two lesions were produced in each pole of each kidney including the cortex and the medulla. In an initial human study focusing on safety, feasibility, and pathology, three patients were treated by RITA with bipolar and monopolar energy. One patient with a peripheral 2-cm upper-pole tumor was treated percutaneously under ultrasound guidance with local anesthesia only 1 week prior to surgery. The other patients, with 3- and 5-cm tumors, were treated during surgery under general anesthesia just before nephrectomy. Ex vivo, the maximum temperature at the active needles ranged from 84 degrees C to 130 degrees C with 10 to 14 W applied during 10 to 14 minutes. Lesions were on average 2.2 x 3 x 2.5 cm.3 Microscopic examination showed stromal edema with intensive pyknosis. No damage was seen to adjacent untreated tissue. In the in vivo procedure, tolerance of RTA as an anesthesia-free procedure was excellent. The size of the observed lesions was comparable to the forecast size depending on the needle deployment. No side effects were noted, and no adjacent structures were affected by the RF ablation. These preliminary studies demonstrate the ability of RITA to produce localized extensive necrosis in kidney parenchyma and tumors safely under local anesthesia. Further studies could evaluate this new minimally invasive treatment in small kidney tumors considered for nephron-sparing surgery.

Neck muscle resistance to head impact.

The role of neck muscles in the body's response to the "whiplash" type of motion which occurs during frontal impact has been studied. This type of motion was simulated by a sudden backward pull of a subject's head. Head and neck response to low-level acceleration has been researched by recording the externally applied force, the head accelerations in the median sagittal plane, and the electrical activity in the sternomastoid muscle (EMG) as functions of time. The resultant acceleration-time curve and recorded EMG have been analyzed, with numerical values of applied resistance to the external force recorded. An analog computer model was built incorporating resistance developed by two main variable: 1) the elasticity coefficient; 2) the active damping factor. Together these two variables, combined with a resistance function, enable us to measure the resistance of the head/neck response. Using this model, variations in magnitude of these two components were studied under six varying conditions of impact: 1) length of warning time; 2) type of instruction given to the subject; 3) amount of previous experience on the part of the subject in similar situations; 4) anticipation of impact by the subject; 5) magnitude and kind of impact; 6) presence or absence of a preload.

[Primary retroperitoneal extra-gonadal germ cell tumor].

Malignant retroperitoneal tumors are relatively rare. The most likely diagnosis by a surgeon encountering a retroperitoneal mass is metastatic disease, but primary retroperitoneal malignant disease or benign tumor should also be considered. The most common primary retroperitoneal tumors are lymphoma and sarcoma. Primary extragonadal germ cell tumors constitute 1-2% of all germ cell tumors, most of which are found in the mediastinum and retroperitoneum. We report the successful treatment of a 20-year-old man whose primary retroperitoneal extragonadal germ cell tumor was treated by chemotherapy and surgery.

[Artificial sphincter for urinary incontinence].

During the past 4 years 21 patients underwent implantation of the model AS-800 artificial urinary sphincter, 4 of whom underwent simultaneous implantation of an inflatable penile prosthesis. The mean age was 48 years (range 33-73). Incontinence was neurogenic in 12 (57%) and a complication of urologic surgery (mainly prostatectomy) in 9 (43%). In 8, in whom intermittent self-catheterization was planned, the sphincter cuff was implanted around the bladder neck, and in the other 13, around the bulbar urethra. The immediate postoperative course was uneventful in 18 (85%), but 2 (10%) had urinary tract infection and 1 had urinary retention. During a mean follow-up of 20 months (range 1-36), 19 (90%) were found to be continent (in 2 of them the cuff had had to be changed to a smaller size due to tissue atrophy), and 1 had suffered from urgency incontinence which disappeared with anticholinergic medication. In 2 with incontinence due to neurogenic bladder, the sphincter had became infected and had had to be removed; 1 of these 2 had undergone simultaneous augmentation cystoplasty. This experience resulted in a change in our policy: we now implant the sphincter and perform augmentation cystoplasty in 2 separate stages. We find implantation of the artificial urinary sphincter very effective treatment for urinary incontinence.

[Endometriosis of the bladder].

We report a case of endometriosis of the bladder in a 32-year-old healthy woman suffering from longstanding suprapubic pain, and urinary urgency and frequency. The disease, which is uncommon, usually has a high morbidity rate and is difficult to diagnose. A high level of suspicion is necessary for diagnosis, since neither the clinical presentation, nor imaging procedures are pathognomonic for endometriosis.
